Paul’s Extreme Sound Stretch
Paul from ZynaddsubFX has written a great tool that is suitable for extreme sound stretching of audio (like 50x) and for applying special effects by “spectral smoothing” the sounds. It can transform any sound/music to a texture.
- It produces high quality extreme sound stretching. While most sound stretching software sounds bad when trying to stretch the sounds a lot, this one is optimized for extreme sound stretching. So, the stretch amount is unlimited
- You can play the stretched sound in real-time (including the possibility to “freeze” the sound) or you can render the whole sound or a part of it to audio files
- Support for WAV and OGG VORBIS files
- It is a Free Software
