<h2><a class='anchor' name='description'>Description</a></h2>
<p>Band Limited ImPulse generator. All harmonics have equal amplitude. This is the equivalent of 'buzz' in <em>MusicN</em> languages.
<p><em>Synth-O-Matic</em> (1990) had an impulse generator called blip, hence that name here rather than 'buzz'.
<p>It is improved from other implementations in that it will crossfade in a control period when the number of harmonics changes, so that there are no audible pops. It also eliminates the divide in the formula by using a 1/sin table (with special precautions taken for 1/0). The lookup tables are linearly interpolated for better quality.<div class='warning'><span class='warninglabel'>WARNING:</span> This waveform in its raw form could be damaging to your ears at high amplitudes or for long periods.</div><h2><a class='anchor' name='classmethods'>Class Methods</a></h2>
