Not quite as good as "NoPingAtAll".

Looks like some tourture room from the 1500's

Did anyone record an impulse response for an Anechoic chamber?

If so, I can make an Anechoic chamber effect using a cut down version of Convo Boy.

Oh man...thanx dude...i needed a good laugh. If you don't understand a word...like Anechoic for example....look it up in the dictionary before proceeding.

If the chamber is really good, you will just get a impulse out as well

that question from a respected developer

like Stefan says: if the room is really anechoic the response and the impulse itself will be identical (apart from gain differences)

I'm sure he was joking

I considered this as well but am not sure...

lol, you're right though...it would be quite disturbing if he wasn't.

Now that is an assumption based on theory. As a physicist, I certainly respect the theory. However, making assumptions that the reality must conform to the theory can lead to a missed opportunity. I would expect a small Anechoic chamber to have a different frequency response at low frequencies compared to a large Anechoic chamber. At low frequencies the dimension of the room become dominant over the absorbent material. At higher frequencies, I would expect the distribution and type of absorbent material to dominate. So, I would be surprised if all Anechoic chambers produced either the same result or the perfect result expected above - I may be wrong.

I guess it is kind of unconventional to suggest measuring an IR in an Anechoic chamber - but therein lies the potential for an innovation.

I can't be the only one curious to find out.

P.S. I was joking about the cut down version of Convo Boy

yeah. it definitely wouldn't be just an impulse. theoretically, yes it would. but even an anechoic chamber isn't anechoic. it's just as good as we can manage to build.

if you look at it this way you're probably right - so your theory is that there is no perfect anechoic room in reality (just like there is no perfect vacuum in reality) - the so-called rooms have the numbers of occuring echoes just drastically reduced... - right?

Yes, but in an anechoic chamber no one can hear you boot the chorus.
