cudasliding — Perform sliding phase vocoder algorithm with simplified transformational FM using GPU hardware.
Perform sliding phase vocoder algorithm with simplified transformational FM using GPU hardware.
iwinsize -- The DFT size in samples. Need not be a power of two. ifftsize determines the number of analysis bins used.
ain -- input signal for transformation.
amod -- signal that modulates the analysed signal.
Here is an example of the cudasliding opcode. It uses the file cudasliding.csd.
