The process here involves taking an impulse response (typically a recording of an impulse or sharp sound in a reverberating space) and an input signal, then for every sample of the input signal, playing a copy of the impulse response with its level multiplied by the value of that sample (positive or negative, so negative values would invert polarity). This would create a "wet" signal so you can mix it with the dry signal at whatever levels you please.

So yes, we are talking triggering waves at sample rate, which could amount to having hundreds of thousands of copies of the wave playing at once.



I think you should perform a search for "brute force convolution" and/or "realtime convolution" on the old site. There are some interesting examples that more or less accomplish what you want to do in a more efficient way than the one you are thinking of (having thounsands of copies of the wave player). And I haven´t tried, but maybe with the new ruby modules there´s a wav to perform FFT based convolution?

Why is it urgent? What are you trying to do?

Hi,... i need a module or code to make convolution of a wav ..to simulate techniques stereo


i mean... i have two signal ..one is a input signal and the other one is impulse response ...i need convolved both to obtain the response :idea:

Kathe,

Look for MYCO in the Synthmaker forum. There is a convolver on there..
Maybe someone can post the link to it, I am just rushing out the door or I would.. sorry..
