STRETCHA is an extreme time stretching plugin for sample files, playing them up to 100 times slower for drone and ambient effects.
STRETCHBPM is for adjusting a WAV sample loop to a new tempo, by setting original and target BPM.
CHIPPER is specialised in stretching or squeezing drum loops. It is a loop slicer intended for tempo adjustment with some extra effects, like playing only parts of the loop or playing the loop slices backwards without reversing the sound.
The plug-ins are available together in one pack as 32-bit VST plug-ins for €6.50.
