Streaming partial track mixing.

<a id="id3303448"></a>
<h2>Description</h2>
<p>
The trmix opcode takes two inputs containg TRACKS pv streaming signals (as generated,
for instance by partials) and mixes them into a single TRACKS stream. Tracks will be
mixed up to the available space (defined by the original number of FFT bins in
the analysed signals). If the sum of the input tracks exceeds this space, the higher-ordered
tracks in the second input will be pruned.

The example above shows partial tracking of an ifd-analysis signal, frequency
splitting and pitch shifting of the upper part of the spectrum, followed by
the remix of the two parts of the spectrum and resynthesis.
