Description

Plugin opcode in cuda. This opcode is part of the plugin repository and has to be installed separately. The plugin repository can be found here: https://github.com/csound/plugins

Perform sliding phase vocoder algorithm with simplified transformational FM using GPU hardware.

Syntax

asig cudasliding ain, amod, iwinsize

Initialization

iwinsize -- The DFT size in samples. Need not be a power of two. ifftsize determines the number of analysis bins used.

Performance

ain -- input signal for transformation.

amod -- signal that modulates the analysed signal.

Examples

Here is an example of the cudasliding opcode. Play cudasliding.csd
