Now what should happen?

Will you hear the snare hit only?
Or
Will you hear exactly what you recorded with no additional reverberant effects?

I would plump for the latter myself...

This is where ARC comes in..

What you hear will probably depend on where it is in the room in relation to where your ear is and which direction the speaker, or your head, is pointing. In other words, it may sound different to either of the two possibilities you mentioned. The anechoic room, I think, will have an effect on the sound that gets from the speaker to your ear.

I have been inside both a reverb chamber and anechoic chamber when a starting pistol was fired. The pistol sounded like a cannon in the reverb room and a tiny pop-gun in the anechoic chamber - it didn't sound like a starting pistol in either.

No, it will not. It would if the sound could bounce on the walls, but it can't. So the only sound that will reach your ears is the sound travelling directly in the air between the source and the target (the ear). The phase and attenuation is a function of the relative position of the target and the destination.

hmmm... I think we need a splitting hairs VST for this one..

I think we all understand each other here, and before it gets tooooo out of hand, shall we just all agree that ARC takes a signal, and puts it out again, in a similar fashion to the way in which an anechoic room will leave a signal alone. (And yes, I've been in one too. Playing and recording drums in one is a quite unusual experience..)

well, I thought about learning to code myself - I think this one I could easily pull off as a first attempt - basically I have the algo already here...

Cue jokes about anechoic chambers and dead popes...

Forever,

there's an anechoic chamber literally 6 minutes walking distance from my flat. and a reverb room. it's freaky as hell being in one. not only from the springy mesh floor holding you above the floor absorbent cones, but the crazy way it feels that you can hear the blood going round your ears. not only is it anechoic but it's acoustically isolated from the world thanks to the massive springs that hold the room away from the ground, and the big air insulation gap between the two outer walls. freeaky as hell. probably the quietest place i've ever been..

haydxn, Is hell really freaky? Dante suggests it ain't, and The Bible says it isn't the place to be.

However, I agree that an anechoic room is rather bizarre..

Ofcourse not. I've never cared about the pope. I will most likely remember him as a twat. Really nice of him to tell people that condoms won't protect them against aids and so forth.

hehe you're probably right. Thinking about it, an anechoic wotsit is more important to me than any Pope dead or alive, and I only just heard about it (or not depending on who's right).
