## shiftin

shiftin — Shifts the contents of an audio variable into a 1-dimensional array.

## Description

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

## Syntax

    kout[] shiftin asig

## Performance

kout[] -- output array, needs to be at least ksmps numbers long.

asig -- input audio

## Examples

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