Detecting whether reverb is present I have two different audio short samples of an instrument playing. If one of the samples has a reverb effect applied, how easy is it to detect which sample has reverb? Is this possible?
A reverb effect usually includes an added, delayed version of the original signal.

Calculate an autocorrelation. If there is significant amount of power at delays larger than what you'd expect for a normal-sized room (say, 1/5 of a second), that'd be a good indication.
