Description

This opcode will display a PVS signal fsig. Uses X11 or FLTK windows if enabled, else (or if -g flag is set) displays are approximated in ASCII characters.

Syntax

pvsdisp fsig[, ibins, iwtflg] 

Initialization

iprd -- the period of pvsdisp in seconds.

ibins (optional, default=all bins) -- optionally, display only ibins bins.

iwtflg (optional, default=0) -- wait flag. If non-zero, each pvsdisp is held until released by the user. The default value is 0 (no wait).

Performance

pvsdisp -- displays the PVS signal frame-by-frame.

Examples

Here is an example of the pvsdisp opcode. It uses the file pvsdisp.csd. This example uses realtime input, but you can also use it for soundfile input.
