I've been having problems understanding how to convolve in max msp.

Do you just input the IR signal? or input the IR and an input signal into the left inlet of the pfft~ object?

I have a lot more questions but I think this needs to be asked first.

I am a beginner!!

If not where do these signals go?

THIS type of convolution wont really work with pfft, because it is too short.

mirroring an impulse response required to do each sample of A with each sample of B.

there is a third party deconvolution object, you might use this. (building a mirrored

file is the same process than using it later as filter or reverb.)

Would I use fft~ and ifft~ objects to make the IR as a reverb plug-in?

Maybe this would be easier than trying to include the input signal at the beginning

i am not sure how to write your own using ifft or pfft object, but i thin i can foresee that it will eat up too much CPU anyway.

what will work as an example is to implement it using buffir~.

but of course that has a certain sample limit as well, and wont do much more than a cheap sounding 2-band EQ or one first reflection for a verb. :)

is there a reason why you want to do your own code in MSP? i think its easier to use soundhack, peak, or matlab.

the download for those HISS tools is still dead ... anyone?

alex harker has made an impulse convolver as part of his suite of objects announced in this thread

i think in the help files there's a reverb via convolution example

I have decided to use the fft~ and ifft~ objects. Which seems to be working okay. However the output signal produced is slightly distorted and quiet... any tips for getting rid of them?

PLEASE HELP I CAN"T CONVOLVE :(
