Blip : UGen : AbstractFunction : Object

Band limited impulse oscillator.
Source: FSinOsc.sc

Description

Band Limited ImPulse generator. All harmonics have equal amplitude. This is the equivalent of 'buzz' in MusicN languages.

Synth-O-Matic (1990) had an impulse generator called blip, hence that name here rather than 'buzz'.

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.

WARNING: This waveform in its raw form could be damaging to your ears at high amplitudes or for long periods.

Class Methods

Blip.ar(freq: 440, numharm: 200, mul: 1, add: 0)

Arguments:

freq

Frequency in Hertz.

numharm

Number of harmonics. This may be lowered internally if it would cause aliasing.

mul
add
