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. |
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.
