Acoustic echo chambers

Postby Terry McInturff on Wed Mar 04, 2009 7:17 pm

Does anyone here make use of true "echo chambers"?

I used to live across a gravel road from an 80 ft tall grain silo. I buried lines across the road and stuck a 3-way JBL stage monitor in there. Then by climbing old rusted rungs that were cemented into the block Id climb up in order to adjust the two mics I had in there. Pre-delay via my old echoplex.

The sound was something Id like to have acess to again! But no more climbing those rungs at 2AM, no thank you! Oh to be 23 again.......

How about it...any micing of bathrooms, entrance halls, and the like? I remember going to the Field Museum and spending as much time listening to the entrance area as I did looking at the first few displays.

Respect for the silo setup. Did you use it as a regular send and return for mixes ? The little experimenting I've done with this has left me thinking its only worth using large spaces, and obviously that depends on location. A friend of mine used to park in a huge underground carpark, so when I met him after work we'd get blasted down there, and I'd slam the car door at least ten times just to hear this cavernous reverb tail, it was lush. In theory, some of these spaces could easily be hooked up as online chambers, upload a file, press the paypal button and you get a silo/carpark/cathedral fx returned in a few minutes. Heck, I have cheap digital reverb and photoshop, why didn't I think of this before ?

Thats funny, there is a silo in Montreal that can be remotely accessed for audio!

I did use it as send/return for mixes, but I often printed FX back then too (still do if its a pivotal part of the performance).

I remember being jazzed when I got my first DDL (effectron) intending to use it for predelay, but went right back to the wobbly old dark echoplex. "Genius moments" (ie love it that night, hate it next morning) would ocassionally involve wanking around with the s-o-s, moving the head around etc. Some of it actually sounded beautifully cruel and was used.

I couldnt use the silo when it rained (had a tin roof) and the ocassional pickup truck passing by made it to the track.

Ive had fun with tiled bathrooms and even stuck a tiny speaker into an open clothes dryer and miced it.

The ductwork in my basement can sound wonderfully gross, if I hi-pass it it has made it to tape but probably only so I could say that I did it.

I like to use our live room as an echo chamber (when mixing). It's aproximately 55m2 and 6m high. The top half of the room has quite a reverb tail. It sounds nice (very live, not too bright). Ideally, I set up two speakers and two spaced omnis about four or five meters from the speakers. I like to swap the LR on the returns from the sends. With a little predelay from a copicat or echoplex I preffer it to the emt 140 or bx20.


Uhm... Here's a picture of the room:

Amazing. Its a remarkably nice reverb considering its a random industrial shape, I became quite convinced it was real after I got some construction work sounds on the tail end! But after two processed files, now I keep getting "file not found on server" when it returns the file...

i have an echo chamber...nothing too terribly fancy, just a 300 sq foot shoebox shaped room with 4 rows of metal shelving to add some "plate" sound to it.

i too add some pre-delay via an analog deck.

it works on some stuff and it doesn't work for some stuff...it just depends...but it's cool!

Using one right now. At KDVS (Davis, CA) we have bands play live on the air and use the hallway as a reverb chamber. We have a rolling unit consisting of 2 speakers and an amp tied to an office chair. It sounds really, really good.

Has anyone been in the parking garage across the street for the century theater in Evanston? Those stair wells are insane. I wish I could bottle it.

I use my bathroom, Its pretty much the most awkward sounding reverb I have ever heard and I absolutely love it.

I concur! That is a pretty spectacular photograph. Very nice for a living room in my personal opinion; my home is itty-bitty. Yes, I know that I'm posting in an older thread, but I was looking up info on echo chambers, soundproof rooms, etc. -- and this is what I just so happened to stumble upon. . . and I thought I'd comment. =P Besides, I'm wanting to do some construction on my home to create a small recording studio -- something that could accommodate sound curtains, among miscellaneous audio equipment. Thought the people on this forum could provide some good advice. =)

The atmosphere kind of reminds me of a small gymnasium. As a kid, I remember the sound in those school gyms having a particularly great echo. Obviously, certain room obstructions would alter the sound, but you get the idea. Was that room custom built or altered to have a particular "sound?" I'm pretty intrigued. Peace, everyone! :smt006

Hi!

I'm glad you like the room. It's very comfortable to record in. Bands feel at ease from the first hour. My idea when building the studio was to have a medium/large recording room with good acoustics and natural reverberation that would compliment drums, horn sections, strings, vocals... (Well, everything, I guess!). My experience recording in Spanish indie/budget studios had been very frustrating (specially with drums). Welsh recording engineer Huw Price exposed me to the importance of great rooms (and a lot more!) . His explanations really hit home when I heard a vintage gretsch drum kit being played in a recording studio called Kirios outside Madrid (Kirios had an orchestral sized room with another adjoining live room and a control room built by Eastlake in the late seventies, early eighties. The main live room was built in the sixties. The control room had a lovely vintage Neve. Couldn't find any pictures that did justice to that beautiful recording room...). Brazil was built entirely from scartch inside an industrial unit/ warehouse type space by Stephen Pickford aka Fritz from eHz. I had a basic layout idea (big live room downstairs, control room upstairs) and knew that I wanted the recording room to sound live but still be able to record an entire band by putting down rugs and placing panels in strategic places. Fritz built a beautiful sounding studio. Years later I brought him back to install the Westlake speakers in the control room and turn a booth into a dead room, a way of working (live room and dead room combination) that I was first made aware of through this wonderful web page. I have found that this set up is ideal for many recording situations. It has changed my life really. We also have a kitchen/stairwell that we use as a second chamber when mixing (or third recording room). It has even longer decay than the live room and can sound darker when mic'd with m130s. A lot of the time it's a self powered floor monitor at the bottom with the beyers in Blumlein configuration at the top of the stairs. I always use tape predelay when I can. A Memory Man pedal can sound great as well!

I did this once.
Put the amp on one side, put the mic facing upwards in the tub. Good slapback thing came out of that.

On a similar subject, has anyone ever mic'd a non-reverberant room and pumped a mix into it. I did this once in my living room because I was working with a recording where all of the sources were recorded separately and the percussion was put on last. It made for a nice cohesive sounding mix that I wasn't really able to get before. It also added a bit of a bottom that the mix didn't have before.
