If I'm correct, an impulse is just a moment where the sample level goes from one to zero, causing a click? I'm interested in doing this still but the things I've found are a little bit technical (explanations, but no practice/application/instruction)... I'll keep looking.

Usually acoustic measurements are done with impulses, AFAIK. An ideal impulse actually has all frequencies in it, so it's useful for that kind of thing. Plus it's easy to differentiate between the initial signal and the room effects just based on time. .hc On Feb 8, 2007, at 3:13 PM, Kevin McCoy wrote: Thank you all for your responses - each was very helpful! I am particularly interested (mostly out of curiosity) in how to "measure" the room with convolution - would I blast some pink noise and then re-record it with a good microphone, and then perform a frequency analysis on that? I am sure I can look this up somewhere. Would this then yield the resonant frequencies in the room?
