<p>trhighest —
Extracts the highest-frequency track from a streaming track input signal.

<div class="refsect1" title="Description">
<a id="id3300614"></a>
<h2>Description</h2>
<p>
The trhighest opcode takes an input containg TRACKS pv streaming signals (as generated,
for instance by partials) and outputs only the highest track. In addition it outputs
two k-rate signals, corresponding to the frequency and amplitude of the highest track
signal.
