It resynthesises the signal using linear amplitude and cubic phase interpolation to drive a bank of interpolating oscillators with amplitude and pitch scaling controls. Resyn is a modified version of sinsyn, allowing for the resynthesis of data with pitch and timescale changes. </p> </div> <div class="refsect1" title="Syntax"> <a id="id3163648"></a> <h2>Syntax</h2> <pre class="synopsis">asig <span class="command"><strong>resyn</strong></span> fin, kscal, kpitch, kmaxtracks, ifn</pre> </div> <div class="refsect1" title="Performance"> <a id="id3163667"></a> <h2>Performance</h2> <p> <span class="emphasis"><em>asig</em></span> -- output audio rate signal </p> <p> <span class="emphasis"><em>fin</em></span> -- input pv stream in TRACKS format </p> <p> <span class="emphasis"><em>kscal</em></span> -- amplitude scaling </p> <p> <span class="emphasis"><em>kpitch</em></span> -- pitch scaling </p> <p> <span class="emphasis"><em>kmaxtracks</em></span> -- max number of tracks in resynthesis.
