Description

This opcode can be used to push data to an audio variable from a 1-dimensional array. The array needs to be at least ksmps numbers long, but can be longer. Data is shifted out circularly, with the writing position moving by ksmps positions every k-cycle. When the array gets emptied, the writing position wraps around to the beginning of the array again. Together with the shiftin opcode, it can form a FIFO queue.

Syntax

asig shiftout kIn[][, ioff]

Initialization

ioff -- initial read offset position (optional, defaults to 0).

Performance

kin[] -- input array, needs to be at least ksmps numbers long.

asig -- output audio

Examples

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