Description

Writes stereo audio data to an external device or stream.

Syntax

outs asig1, asig2

Performance

Sends stereo audio samples to an accumulating output buffer (created at the beginning of performance) which serves to collect the output of all active instruments before the sound is written to disk. There can be any number of these output units in an instrument.

The type (mono, stereo, quad, hex, or oct) should agree with nchnls But as of version 3.50, Csound will attempt to change an incorrect opcode to agree with the nchnls statement. Opcodes can be chosen to direct sound to any particular channel: outs1 sends to stereo channel 1, outq3 to quad channel 3, etc.

Examples

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