ins

ins — Reads stereo audio data from an external device or stream.

Description

Reads stereo audio data from an external device or stream.

[Warning] Warning

This opcode is designed to be used only with orchestras that have nchnls_i=2. Doing so with orchestras with nchnls_i > 2 will cause incorrect audio input.

Syntax

ar1, ar2 ins

Performance

Reads stereo audio data from an external device or stream. If the command-line -i flag is set, sound is read continuously from the audio input stream (e.g. stdin or a soundfile) into an internal buffer. Any number of these opcodes can read freely from this buffer.

Examples

Here is an example of the ins opcode. It uses the file ins.csd.
