Resynthesis – making small samples longer

There are a variety of ways to do time stretching without changing pitch (i.e. elongate a tail).

You could use FFT to create a phase vocoder. There is a phase vocoder example in the FFT chapters in the MSP Tutorials. There is also this article on building a better phase vocoder in MSP:

Or see Jean-François’ FFT/Jitter examples for ideas for how to build a phase vocoder using Jitter:

Another time stretch technique you could use is granular synthesis. You may want to check out this thread:

Also, there is a third party external for Max that actually uses the same time stretch algorithm as Ableton:

infinite reverb with a long envelope is a personal love of mine to extend too short envelopes, but that might be too artifical…;-)

Tonight is premiere of Salomé in Stuttgart, I’ll look for it later and create a little M4L device…;)
