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

<div class="refsect1">
<a id="idm281472890207784"></a>
<h2>Description</h2>
<p>
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.
