I'm running a project related to psychoacoustic and I want to be able to Increase/Decrease the number of Acoustic Event (or acoustic emission) of crack sounds, during the mastication process of some crispy products (i.e. for an acoustic wave in the time domain, the signal crosses a preset threshold a certain number of times. To calculate the number of acoustic event you'll just have to count the number of peaks that are above this preset threshold).

So I want to modify the original sound of mastication (sounds are mainly cracks and snaps) and replay it to subject’s ear in “real-time”.

Delay between original sound and the modified one has to be imperceptible to subject. That's why I need to perform effects in real-time.

I want to apply this effect, in Real-Time, on audio input, without affecting the length of the original sound (duration), the pitch, the timbre and the loudness.

Is there any effect available that I could use for my application?

What is the maximum delay tolerable, between original sound and modified feed back, I can have in such way that the delay is imperceptible to subject (normal human being)?

Is it even possible?

How to Increase/Decrease number of Acoustic Event (acoustic emission) in Real-Time?
