I would so love to share some in depth observation or revelation of usefulness that would leave all that read these words with a smile. Hopefully by the time time I finish writing this entry, I will stumble upon something down those lines but in the mean time I will offer a brief update on my wanderings.

Though no one like a quitter, I did take a small break from my break from mixing bands. Actually, it does not really count because I'm not against mixing, just trying to see if I can both survive and not tour at the same time. Anyway, off to Santa Monica to fill in for my good friend Craig Overbay who mixes Weezer.

The morning radio shoot was not a major enough of an event to fly Craig down from Seattle so I got the honors to fill in and actually quite enjoyed it. Here is a live video from the radio show:

Cool how the Rat made it in, not so cool that the camera has trouble finding a focus. For those of you who may not be familiar with Weezer's actual Pork and Beans video, it is really cool! They went and found the people that did the most popular YouTube videos, flew them all out to the same place and filmed a Weezer video based on the YouTube videos. This site has a link to the Weezer video and then links to the original video from which Weezer built it. It is worth a watch as some of them are really funny!

I received an email asking Rat was ok with a post on MetaFilter and to be honest, I had not heard of it before. Anyway, I guess I am in the minority there cause after the post went up, I got a bunch of emails from people who saw it.

What else, oh! I went to see Radiohead at the Santa Barbara Bowl and they were touring with the new L'Acoustics K1 system.

Here you can see 4 K1 subs per side at the top of the array, 8 K1's per side, 3 dV-Dosc per side and 3 clusters four SB 28's configured 3 forward and 1 facing backward in each. Also there are some assorted deck fills. As expected, the system was clean, clear and impressive, nothing surprising other than how darn great it sounded! I want one! This is destined to be the sound system by which all others will be judged.

While in the sound side of things and in web cruising video mode, check out this video EAW made covering the MicroWedge features. Love to hear comments on it.

On a less cheery note Dolby has announced that their state of the art processors http://www.dolby.com/professional/live_sound/Products/lake_processor.html

will be discontinued and users have less than 30 days to place all orders for any units that they will ever need for ever and ever.

Since its introduction, the Dolby Lake Processor has helped the world’s top touring sound companies and performing arts centers to improve the performance of their systems and has been widely recognized as the state of the art:

As Dolby looked to the future, we observed an accelerating shift toward integrated speaker processing, equalization, and digital audio networking into amplifiers and powered speakers. As a result of these observations, Dolby and Lab.gruppen developed a program to take advantage of this trend by creating an amplifier that integrated DLP technology. So the Lab.gruppen PLM 10000Q Powered Loudspeaker Management system with “DLP inside” was launched to great success—and we understand that more models will be introduced soon.

With the success of the Lab.gruppen project, and to align Dolby with our future corporate strategies, we have decided to exit the Live Sound business. As a result, we are announcing the final production run of the DLP, after which we will discontinue its manufacture. We have allowed the next 30 days (through September 30, 2008) for you to calculate your needs and to place final orders. This final production run will be set to fill the open orders we have as of the close of business on that date. Delivery schedules may vary from our previous norms, so please plan accordingly.

Dolby is committed to supporting both the DLP and Lab.gruppen’s efforts for the future. We will provide our standard warranty coverage and one-year of software maintenance on this last run of DLPs (see the attached Warranty Statement and End User License Agreement for these details). Dolby is no longer developing new features for DLP or Lake Controller software after release 5.1.

We would like to thank you for your support and hard work as we built this business. Your dedication and enthusiasm for the Dolby and Lake brands was a key component of the success we achieved. We are gratified to know that DLP technology will live on through our partnership with Lab.gruppen and we wish each of you much success in the future.

All I can say is Yikes! So glad that Rat Sound went with XTA processors, and my heart goes out to the companies that are mind crunching the decision of whether to stock up or liquidate their DLP inventory.

Stepping back and looking at the bigger picture, as drastic as this notice seems, it does highlight something interesting. Just as the Line Array caused a monumental shift in pro audio, I believe we are at the doorstep of another massive shift and the days of the "dumb amp" in cutting edge audio is over. These new generation of smart amps are incredible. Things like being able to sense the impedance profile of the speakers connected to it and tell you if the system is wired wrong and what type and how many of each speaker type is connected to the amp is just the beginning! Exciting stuff so perhaps rather than loose too much sleep over last years processor, may as well start diving into next years Procamplifier.

And for the smaller companies? Well, expect a lot of cool used amps and processors to show up over the next few years as we audiots make this painfully expensive step forward into yet another new realm.

Other news and such, I had the pleasure of seeing Jack Johnson

and Bob Dylan as well, as I got out and about and I really need to figure out a new system to remind me to bring my camera. The whole "attach it to the Peppers laminate plan just does not work well anymore.

So I found this interesting

http://www.audioprointernational.com/news/625/JBL-rocks-Rio-with-Gabisom

and I was happy in that one of the larger festivals in the world has adopted the double hung PA concept and an honor that something I spent so much effort on, is catching on. And saddened a bit as well that the company did the press releases as if they had come up with the concept on their own. Which is entirely a feasible possibility as the idea of a side by side PA makes a lot of common sense. Had I not been at that same festival:

http://www.google.com/search?sourceid=navclient&ie=UTF-8&rlz=1T4FUJA_en___US237&q=Gabisom+Rock+in+Rio+Vertec+Dave+Rat

on the last Peppers tour while touring with a double hung PA, I discussed the concept with that same company, it's feasibility and advantages. Otherwise, I would have given them the benefit of the doubt that they stumbled on the same idea. That is not to say that the Peppers tour was the only time versions of a dual system have been implemented, though to the best of my knowledge, the Peppers tour was the first time it was implemented to increase the headroom and clarity of a large scale line array system.

Me? well, I have been reading emails and notes an such sent to me but lax on responding much. So strange how time slows down and all the gaps fill when I stop moving around the world quickly. The question I so often heard, "Where do you get all the time to write the blog?" is now one I find myself asking.

Speaking of time and being honored, I am taking the time to travel up to AES as I have been asked to speak on a workshop forum discussing microphone techniques.

http://www.aes.org/events/125/livesoundseminars/session.cfm?code=L8

Fair enough, I can handle talking about that and what is really cool is that I will be on the forum with none other than Dan Healy. Some may ask "Who is this Dan Healy guy?" Well, Dan not only mixed the Grateful Dead for many years but also was involved in developing the "Wall Of Sound" PA.

Seven months home and the rhythms of tour are as clear in my recollection as the food I ate 7 weeks ago tuesday and even if I mind-smunch my brain deep enough to retrace my steps, I could not possibly recall more than rudimentary guesses as the sensations and aromas have long ago drifted into oblivion. Where does my time go? And why do I let running around in daily circles sponge my life away into gas receipts. How is that important? Yet the desire to get there or here can seem so desirable and crucial and looking back all I see are tail lights and patches and broken things and a few smiles at the moments when I broke free of the pattern. Oh to look forward to a magnetic future that pulls happiness from the monotony. A single phone call holds the power to shift drudgery into closed-eye bliss or to obliterate euphoria into a slap-stinging reality of the past haunts I've created. Run away! but I wont as I have chosen to stay. I have stepped off the moving ship that allowed me to live in the disconnected reality of motion. Sir Isaac Newton, the falling apple on the head guy, once said "an object in motion will stay in motion till acted upon by an outside force and an object at rest is bored." Or something like that. Do we watch the movie or do we strive to be actors? Ooooh! The beauty of disconnected observation. And ooooh, the temptation of jumping into the limelight of celebrity attention. Each with their downfalls both so alluring depending on the moment. Claps and cheers for those who ramp up and are willing to crawl out of their defeats on the way to success. Boos and hisses for those that crawl shifty behind deception to force their greedy goals. Am I wrong to remember gas was $1.50 a gallon when "we" (in the soft and broad unfortunate form) elected that slurring annoyance? Ah, but is it so wrong that the spiraling bumblefuck around us is reinforcing we humans into getting our shit together and bumping up our minimization of crapping on the earth about us? Ah the "Barney Syndrome," the purple dinosaur so bent on happy-cheery and perfect it invigorates resentment in even the most kind hearted observer. A peon propped into power so bent on ass kissing his indebtedness away to the string-pullers that all he touches begins to decay, creates the Barney syndrome in reverse. Here we sit at a hopefully a zero crossing upward as the natural oscillation from dark to light, fight to fun and falling to climbing enters the next stage. Speaking of the cycles and competitions of life, check this out. I would like to say nothing makes me cry but I have spent too many plane flights with sunglasses on watching sappy movies to say that with any integrity, anyway, this video made me smile with watery eyes so I figured I would subject you 'all to it as well:

And out of the ramble and into midst lets go for a wander to see what we can find in the world of France. Meet Christian Heil, the big kahuna creator of the modern line-array sound system configuration. For those of you outside the audio realm and maybe some within, in the mid to late 90's a PA created by a French company called L' Acoustics began gaining considerable traction on large tours with a system called V-Dosc. Immediately all the major players in the speaker building industry started coming up with reasons the line-array systems do not work and are inferior. Then they realized that there profits were in jeopardy so they all copied it. Today, with only three manufacturers that I know of,

I tour well. Perhaps naturally nomadic or maybe just that I have spent much of my adult life traveling between hotel rooms. Either was, landing myself down in one place for more than a few months is an incredibly challenging process. First there was the hazy shock of solid ground, the realities of washing my own clothes and figuring out the proper food purchase to consumption ratio. The glory of a full fridge followed by the dread of tossing away piles of rotted food only to be followed by scouring the kitchen for something edible. Then sets in the dreaded weight of repetitive patterns. Drive to work, wash car, clean house, being at various places at certain times. All the while fighting the sensation of collapsing freedoms. I tell myself it will be ok once I get used to, I tell myself that tour looks so shiny from a stationary standpoint and try and keep the downsides in focus so I do not slip away into "grass is greener on the other side" envy.

As I navigate the doldrums and desirable aspects of the non roadie lifestyle, the bright spots of my days pull me like magnets past the trenches. One of those magnets is surfing so I would like to introduce you to a few friends that form the core crew. Meet Randy, John, Mac and Ray with whom I spend the crack of dawn surveying the waves before diving into the icy waters. I would like to thank John for the loaner of the rattle snake skin hat for the photo op.

And No Wave Dave who's ability to focus right in on what I call "poking the bear" is a constant source of smiles.

And Gene whom I hold I hold personally responsible for getting me hooked on surfing and spending my mornings hanging out with this motley crew.

Gene and Dave are not part of what they term the "goofy hat wearers." Clearly, I have no issue with it. Speaking of snakes, snaking is a term used to refer to the act of taking off on a wave in front of someone which you can see occurring to Gene in the photo below. You may also notice Gene entering "the bear pose," a clear indication that he is less than pleased with the maneuver.

And to better enjoy the adventure in wave, hey, why not make something a bit different and fun? Hmmmm, how about a custom Surfboard? Well, upon searching through my computer I seemed to have an abundance of a certain logo so.....

I sent out the graphics to Ray and had some silk printed and the Blinky (William Dennis) at Ventura Surf Shop made it up for me. Thank You, the board rocks!

Moving on to another source of smiles, here is a picture of a speaker I made with my mom on Christmas day. Together we worked in my garage just hanging out and though I am not a celebrator of corporate holidays, this was one the best Christmases ever. It is a 6 feet long polished aluminum tube with progressively dense filler and an open back. The tweeter is a bundle of 6 microphone capsules. The sound is amazingly clear and open.

Oh, and I have another way cool aluminum tube speaker coming. Just thinking about that zone and rhythm of building creations in the garage makes me happy.

First in line of the source of "making home being worth while though is being soccer coach for AYSO U12 girls team and going to softball games to watch shorty #1 and #2 rock out on their sports skills.

MicroWedge 12 is out and about and in bloggery modern networking tradition, I even persuaded EAW to embrace an "Official MicroWedge Myspace Page."

http://www.myspace.com/microwedge

How many wedge's have their very own myspace site? Ha ha! Al in good fun and I made a little slide show as well.

Also the official EAW MicroWedge site is up as well.

http://www.eaw.com/products/microwedge

So I head out to EAW about once a month for all kinds of secret designing and such. The all new EAW MicroWedge 15 that is smaller and sexier than the old one, an EAW MicroWedge 8 and Shhhhh.... rumor has it, if I was to spread rumors, that a speaker box like you have never seen of the ultra cool EAW MicroSub 15 could very well be in the pipeline. I so wish I could share the MicroSub 15 prototype pics as it is a design I have been working on for a long long time and finally unraveled the answer to what I believe to be is the most useful and versatile stage sub ever. And it looks cool too!

Ok, I will try and pick up my bloggery pace a bit from once a month but no guarantees other than I will be back.

Rock On!

Dave Rat

Well, it has been a bloggery while since my last post and not for forgetting, as I truly have been intending. Being in the sound company business is not for the faint hearted and winter time is the toughest of all when you depend on touring bands as your primary income.

Way back in 1980 I started Rat Sound with my friend Brian when we both worked at Hughes Aircraft. Prior to that I was recording bands and though we did not adopt the pet name Rat for a few more years, 1980 is really when it began. I had started at Hughes in Radar Systems Group testing components for jet planes like the F/A 18, F15 and F14 fighters. Got bored and worked it out so I was loaned to Space and Communications Group doing a similar but less monotonous gig for Telstar and Telsat satellites. Still bored I applied for a transfer and was picked up by the engineering department of Electo-Optical Group working on TOW Missile systems. Youngest guy in the department and the only one without a college degree, it was actually pretty darn fun, for while. Military government paperwork sucks! Meanwhile, nights and weekends I did rock shows, punk rock shows mainly with big band and 60 piece orchestras scattered amongst the sundays.

Every cent I had went to PA gear, I had no savings. Mid Reagan era military expansion filled my non-gig weekends with overtime at my day job. In November of 1980 a giant fork appeared in the road ahead. My vacation and sick leave time had been consumed by friday load-ins, rumors and memo's regarding various departments enacting mandatory overtime were abound and I was making as much money doing rock shows in two days as 5 days of my 7am to 3:30pm "real job" landed.

Career, medical benefits, retirement plan and some semblance of parental respect versus late nights, loading trucks, loud music and freedom. December 12th I gave 30 days notice. January 12th I was free. February 12th I was broke, hungry and selling off sound gear to buy food and gas. That was when I learned, the first time and then proceeded to learn every year there after. With a few exceptions, winter means starvation for furry little critters and touring sound companies. It is never a surprise, at least not anymore, but that does not change the fact that it is a challenge.

Now a days, it is different than it used to be. Now the threat of not eating is long gone while what remains is the necessary time, care and focus to navigate the ship through the low tide. So in short or in long, that is what has grabbed my focus and what I have been up to.

**** Sound Nerd Speak ****

MicroWedge update. First the official stuff. The new EAW MicroWedge 12's are done and the first delivery will be at Rat any day now (read "tomorrow"). Processor settings are done and super cool! There are three settings and they will be coded as colors.

White - The Flat Setting. I don't have the final spec yet but it was plus or minus a couple db throughout it's frequency range. This is a industry standard starting point so engineers can tailor the EQ to suit a wide variety of applications.

Gray - A 1 db per octave slope rolling off as frequency increases. A warmer setting that sounds more natural and requires less EQ to dial in.

Blue - We took several industry standard microphones, plotter their real world response and created a curve that counteracts the inherent peaks. It was surprising how similar the Neumann, Sennheiser, Shure and Audix responses were. The Blue setting is tailored to get very loud, not feedback and sound amazing with no external EQ and reproduces both music and live mics extremely well. True plug and play usability.

Now for the rumors. If I was to say, I would say that a new sleeker, smaller, louder MicroWedge 15 and more is hot the tails of the 12", though the Micro 12 was developed to go lower and get louder than the best 15" monitors out there already. I would also say that cool new tilt legs (The MicroLeg) are being developed and they allow the MicroWedge's to be utilized at various angles. Say bye bye audio blocks, say hello to optimum wedge angles!

Oh, and I wish I could show you the latest MicroSub prototype but that would ruin all the fun and anticipation. I will say that if it makes it through the maze to market, it is useful in ways unlike anything else out there and is something that the few monitor engineers I've shown it to already have all said they could use them right now.

Speaking of useful, I was at the NAMM show and stumbled across a few items that I can not imagine how I have managed to live my life without. First we have what appears to be the ultimate PA speaker.

Not sure if it is a 5 way or a 7 way stack but wow, that is a high concentration of Piezo speakers.

Next in line, I find myself wondering "am I the last know?" and "how come everyone does not have one?" when I spotted this beauty:

That's right, a 7 string bass! Clearly marking the end of the 4 string era.

But wait, what do we have here? Is it? Yes! A guitarasurus!

So handy yet so eloquent. And if one is to rock a guitarasurus, one had better get an adequate guitar rig. Hence I present:

The ultimate rockers dream and sound guy's nightmare. "Yes, of course they are all plugged in, why else would I have brought what I need?"

And so it was and off till next time.

Dave Rat

Hours fill up faster than new ones can appear and I scribble little hieroglyphic notes of future events I wish to remember in places I hope not to forget. This is either the best time of my life or just another meandering plugging away in some pipe dream direction. I guess both are true and unlike the thrill of exhilarating adventures, at least the' right now' I live in wont have the hangover that follows overload fun excursions.

Challenge is the foundation of motivation. The knife that divides the complacent from the relentless. My sour reactions of being caught off guard catalyze into that desire smile of harnessing the energy to overcome the annoying. To try and stop time is to become lifeless. Growth or deterioration take your pick. Stagnation is celebration turned rancid. On some levels I could not be happier as my dreams unfold and my stumbles remind me that I am as disoriented, lost and confused as I have always been. It is amazing how chaos is just one phone ring away from from bliss. Yet in the slightly bigger picture, everything remains amazing. I hop out of bed for a while each day and try to remember to eat before my vision blurs and I wander about my night thought balancing life between shoring up the sand-castle walls against relentless waves and adding drip towers to the delicate city within. Speaking of shoring up walls, occasionally a rethink is in order and an open mind realizes that a new direction is better so back down away the walls need to go. Say bye bye wall!

And since we are at the beach building castles, let's have a Halloween party! Meet my niece Jessy, don't be scared, she is not a real lion:

And a few more of the various family and friend critters. Food attracts critters.

**** End Sound Joke of the Day ****

Easily the most sobering aspect of being home is the reality that behind the veil of the shiny lights, rock shows and music that makes us smile in our headphones. The music business is a ruthless cut throat industry peppered with wolves in sheep's clothing, poisonous ego's and finger pointing incompetence teetering on back room money deals and good 'ol boys patting each other on the back. Put another way, no real shocker here as the music business is just like churches, corporations, governments and just about any other organized human endeavor. Oh those silly humans, what do ya do about it? Cry? Ha ha! No way! Going to muscle it up, hang tight with the ones I trust and build up those sand castle walls with a smile fully knowing that it is just a matter of time before they are washed away someday, anyway.

Clearing my thoughts for more enjoyable train of though, let's go visit Gwen! A success story with a smile and 'way back when' I remember the day she pulls a cassette copy of the new and first No Doubt album out of her purse with an ear to ear smile. "We got signed and here is rough mixes of our album!" The excitement and a get to hear a quick listen. I just love how you never know what will happen next.

And next up.... Story and recommended reading of the day is do a Google search for "Steve Jobs Commencement Speech Harvard."

Do you Have the Time?

Ok, here is something that seems to perplex or be a bit of confusion with some of us sound nerds. There seems to be a bit of confusion floating around regarding whether sound signals travel faster in in snake cables or fiber optic cables and where the true and relevant sources of time lag lay in an audio system.

The sound signals travel at differing speeds depending on whether it is in the form of electricity, in the form of sound waves in air or passing through various commonly used bits of audio gear. To make things simple, I will just approximate a bit.

In 1.2 milliseconds of time:

#1 In air, sound will travel about 16 inches.

#2 Under water sound travel near 5 times faster and would cruise about 70 inches.

#3 In 1.2 milliseconds sound will just barely make it from the input XLR to the output XLR of a Yamaha PM5D digital console and you can make it a bit more than half way through a Digico D5 because it takes 2 milliseconds for a signal to escape a D5 once you put it in.

#3 Perhaps surprisingly though, your audio signal will travel about 650,000 feet (124 miles) down a regular copper mic cable or snake because in copper electric signals travel about 2/3's the speed of light.

#4 Even faster, your audio will travel about a million feet (186 miles) down fiber optic cable but it can take over 630 micro seconds which is over 1/2 of the 1.2 milliseconds to convert from analog to digital for light at each end so you would not quite make it out of a fiber cable even an inch long but if you already started with a digital signal, figure the conversion to only takes about 10 microseconds from electric digital to light.

#5 You could probably put every piece of analog gear you have ever owned or own in series and run a hundred miles of mic cable and still have some extra time left over because most analog gear has almost on time lag..

So, where is time lost and how important is it? Mainly after it leaves the speakers is the big issue and secondly, before it hits the mic. From there it flies through analog gear so fast that it can be considered instantaneous for most purposes. It gets a bit more confusing with digital gear because the sound signal makes little 'pit stops' whenever it encounters a a 'digital to analog' or 'analog to digital' conversion. Also, unlike analog gear, once the signal is inside a piece of digital gear, the signal can slide behind in time further as you add processing to the signal, unless the manufacturer has implemented compensating delays that lock the delay time at the max processing time.

What does this mean, well, for the most part, the time delays we are talking about are so short that they can be discarded as irrelevant but... if you electrically are recombining signals, it is critical that they are not shifted in time unless you desire a phase shifter effect.

OK, enough for now and soon some more.

Dave Rat

Well, how about an update on the way of world of being home. I went for a visit to say hello to the Foo Fighters and crew at their rehearsal prepping for the Europe tour. They are one of the greatest bands all the way around. They rock, they are all super cool people, they have fun and their music is awesome, all good.

They have a pretty cool tour setup planned out and if you have not seen Foo Fighters live, I highly recommend you do. Next stop for me is AFI. I am trying not to tour and steering clear of mixing shows as best I can to stay focused on other things but when the call comes in to cover a gig, and it is just three shows and not far away, well, I could not help but say yes. Rat has been supply sound gear to AFI for several years now and this was my first real chance to meet and get to know them a bit better and it was all good.

**** Sound Nerd Speak ****

Next stop in my travels is EAW for some more design work on the new MicroWedge.

Every single detail is addressed and I absolutely love it, it is a dream come true as I have always envisioned the way that the product should be and finally I am surrounded by an infrastructure that not only "gets it" but also has the capability of implementing it. The reflectivity and hardness and texture of the external coating, the exact round over radius of every edge, the shape, feel and depth of the handle. The center of gravity, grill material, mounting and coating. The switch placement, fly hardware, feet material, shape, logo design and dimensions. Oh, and the sound aspects are even more detailed. Tune, test, refine, repeat. Even after dialing in the optimum coax component frame, come and driver, it was time to address the speaker dome (dust cap), material and shape and cone coatings, glue thickness, the internal damping material type, thickness and mounting. Tune, test, refine, repeat. Exciting stuff and all the while I refer back to stable reference points so I do not get lost in the sonic direction headed. And I carry my notes and refer back to the overall concept of the Micro Series. Non-processor dependant designs that naturally sound good without electronic enhancement. Electronic processing then can be added to further optimize the designs. Though the Micro's do have passive crossovers in them, in both old and new Micro's, the biamp switch completely removes the passive crossover from the circuit and allows direct connection from the amp to the drivers.

Oh, and as I have been asked to many times here in bloggery world, I have been approached about maybe teaching a seminar on sound subjects. Actually I have been approached several times from various entities and when things settle down a bit more for me I plan on speaking at a few colleges that and sound schools, but most recently was one that is a bit more open format. So let me ask you all this, if I was to teach a sound seminar, is there anyone that would be interested in coming to a sound seminar and if so, what topics or concepts would you be interested in?

**** End Sound Nerd Speak ****

What else? Well, there was an article on sound humans blogging http://www.nxtbook.com/nxtbooks/newbay/prosound_200709/index.php?startpage=0

If you are a subscriber to PLSN or FOH Magazine you can now vote for the awards. http://www.parnelliawards.com/vote.php

Though the whole concept of awards shows does not sit too well with me. I always get this feeling that the same insiders just gather round to pat each other on the back once a year. Oh boy look! The same people won 10 years in a row again! Hurray! Yet I also know that when do actually vote, I often find that I am not that familiar with the various categories and contenders and there is a temptation to vote for the one I have heard of, hence and most likely the reason that the outcomes are typically less than exciting. All that said, I do like the exceptions to the rule and in a way, it makes it all the more enjoyable when an outsider to the "good ol' boys" takes the prize.

Anyway, I will be headed out to Florida for LDI. You know that saying, "what comes around, goes around?" Well, back 2005 I wrote an article for FOH Magazine http://www.daverat.com/ldi.htm and the trimmed version is up online at http://fohonline.com/index.php?option=com_content&task=view&id=443&Itemid=1. As the twists of the world would have it, EAW is going to be one of the stages at SoundHenge also know as ET Live. Oh jees. Not only did ET Live they quote my article to promote the event (yes, they did ask first) as fate would have it, guess who they asked to mix on their stage this year? Most importantly, check out my hair cut in the quote photo.

**** Dormant Roadie Babble ****

So sorting through some pics and since Leeds was the last show I was pretty pre occupied with wrapping up odds and ends so not a lot of photos. I did find these. The magnetic attraction fire does seem to go quite well with music. Add in some food and it somehow highlights the human-ness of it all.

Oh and found this from Glasgow I think. Wow, this is one heck of a facility! "Man and woman make baby in shower." And even the slippery floor warning, so be careful.

So I am hanging out and a critter cruises by in the night in the back yard. The combination of curiosity and hunter instinct sets in and so I decide to trap whatever it is and wake up to find this little guy.

Cute little baby possum and very stinky as well. Well, I don't mind 'em running around so I did what any considerate person would do, I let him go in my neighbors yard.

Been getting a bunch o requests to take a look round the home I occupy so here are a few. I while back I bought some old recording studio sound baffles and combined them with some excess shirts from past tours and gigs I have done. This would be in the dining room. That purple shirt with the satan on it says Red Hot Chili Peppers, Nirvana, Pearl Jam." Imagine if that tour happened now how big it would be!!

My home office.

And as we head to the Rat Shop I find Ben de-prepping the Peppers FOH console as it re enters the rental inventory. All those wires were in the back of my board, yikes!

Dynamic vs. Compressed.

So a while back I was pondering mixing live shows, as I strangely so often do, and I started analyze the varying aspects of dynamics in live reverberant fields. Is there something more legitimate than personal preference that would add credibility to using compression? The studio humans and mastering labs use a tom of it, but comparatively us live engineers use fairly little. I know it works well to control the variations in the band's playing and helps with smoothing the sound but there is yet another advantage of compression that is not so readily apparent.

On the surface it is quite obvious that compression can be used on bass to reduce the differential between the louder and softer notes resulting in a more consistent sound. Same with vocals and I put comps on guitars as well. I even take it further and run kick and snare into a subgroup that has a bit of compression on it to keep the two locked in a bit more volume-wise to each other.

So what got me started again on this train of thought was not long ago I was listening to a super punchy horn loaded rig. Boom, crack, boom, crack, as the drums jump out at me and they do sound cool. But I also know from experience that the reverb decay time from the loud 'on top' super punchy sounds blurs the intelligibility of everything else. If an uncompressed snare is 10 db 'on-top' of the mix, then the correspondingly loud roar of the room-reverb-decay-level from that snare would hurt overall intelligibility long after the original snare hit has been heard and ended. Conversely, that means that if the instruments are all compressed to a fairly narrow volume range, they then would stay at an even level consistently above the room reverberation rather than the loud sounds setting off room reverberations louder than the following softer sounds.

What I am getting at here is that controlling the differential between the loudest and softest sounds not only improves intelligibility by reducing volume inconsistencies, it is also helpful in dealing with reverberant room acoustics. The sacrifice? Well, you loose some of that slam- hit eye-blinking impact. But hey, the upside is your mix will sound a bit more like an album, the audience will be able to hear the various instruments and vocals better especially in reverberant rooms, and you will be able to get more overall volume from the PA with less clip lights flashing.
