Dear Great Max-lovers,
I have a simple question which I want to get a thorough understanding of pfft~ and realtime convolution in Max/MSP.
If I design a FIR filter, I usually use buffir~ object but the buffir~ limits the number of taps.
For a longer FIR filter (such as a room IR), I want to make a pfft~ based fast convolution.
I know that I can use HISSToolBox for this purpose ... but I want to try and design my own one.
In my first trial, I compared buffir~ and pfft~ for a short FIR (2048 taps), expecting that those two would generate same results.
But the results were quite different.
If one of you could let me help to debug this and remove this difference, it would be helpful for me to move forward.
Many thanks in advance.
