<p>trshift —
Streaming partial track frequency scaling.

<div class="refsect1" title="Description">
<a id="id3304127"></a>
<h2>Description</h2>
<p>
The trshift opcode takes an input containg a TRACKS pv streaming signal (as generated,
for instance by partials) and shifts all frequencies by a k-rate frequency. It can also, optionally,
scale the gain of the signal by a k-rate amount (default 1). The result is frequency shifting of
the input tracks.
