Write a fsig to a PVOCEX file (which in turn can be read by pvsfread or other programs that support PVOCEX file input).

Syntax

pvsfwrite fsig, ifile

Initialization

fsig -- fsig input data.

ifile -- filename (a string in double-quotes) .

Examples

Here is an example of the pvsfwrite opcode. It uses the file pvsfwrite.csd. This example uses realtime audio input.
