I've made use of micro echo-chambers by placing the mic into a large coffee mug... to get an AM-radioo style vocal effect. It did the job.
It's here, on the song Porch Party Wine http://www.myspace.com/benthebutcher

He's a good dude. He used to run a massive complex in Finsbury Park under Sweet Georgia Brown's, where we had a little studio stuck on the side.

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.


I really like this idea. A variant of this is running a send of whole mix through a live or dead studio room or impulse response file thereof.

I now have it in my contract that at least one element of a mix will go across the hall into the tiled bathroom!!
Super 70 studio is in an old high school and the boys room is right across from us and as we only have 3 rooms on our wing we have it to ourselves most times.

Been putting a pa speaker there and a 57 for vocals or drums and it sounds great.

Also been recording guitar amps in the hallway close mic'd facing the bathroom with a 57 facing into the bathrroom about 1 foot in...sounds amazing.

Anyone in need of a really long reverb?

Acoustic scientists emerged from the Inchindown oil storage tanks, an underground fuel depot constructed during World War II, with proof that a gun-shot fired inside the tunnel resonates for a full 112 seconds.

That is great. Would love to go in there someday.

I always thought it would be neat to try to build a huge anechoic chamber, like the size of a football stadium or bigger to get acoustic delay without echo. There's probably an easier way to do it, but that was my idea.

I think such a line delay would be a very useful tool. You should add a huge HVAC system, so you can fine-tune the delay time by cooling the place down (or by turning up the heat).

I believe he came over to build our studio just after he'd finished Sweet Georgia Brown's and the massive complex, which, if I remember correctly, was called Unit 11.


I've been away from the forum for a while and it's great to be back.

Hi Guys,

Sander here from the Netherlands.

Just registered myself here to add some special idea to this topic.. of which I'm pretty sure least 50% of you have never heard of before :D

It is in reply to what Tom wrote about his stadium Idea.. yes Tom, there might in the near future be a better idea, but you've got to go "ultra-sonic" for it.

check this out: http://patents.justia.com/patent/20140369513

And: http://www.ecolivegreen.com/products-ecolivegreen.html

I stumbled upon it, basically, because this guy was just 1 year earlier with his patent.. I had the same idea, but was unfortunately not near in a position to properly work it out ; not even close to a test model, but pretty sure it must work.

How's that for a reverb chamber!! Hope this inspires folks who finds this thread, I would never have been in for such an idea for $$, I'm just too d*mn curious if this would work and if so.. how does it sound?? What are the possibillities??

Imagine creating your own reverb box inside a tank.. man, that would be awesome

Hey, I know it's not the same but you can download the impulse files from here (you can use it with ReaVerb, of course):

In case that someone's interested, Trevor Cox (the guy who made the measurement) wrote about it on his blog:
