cudasliding

cudasliding — Perform sliding phase vocoder algorithm with simplified transformational FM using GPU hardware. Experimental and only available as source code at the moment.

Description

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. It uses the file cudasliding.csd.

Example 1225. Example of the cudasliding opcode.
