synths.lib

This library contains a collection of synthesizers. Its official prefix is sy.

A simple percussion instrument based on a "popped" resonant bandpass filter. popFilterPerc is a standard Faust function.

popFilterDrum(freq,q,gate) : _;

Where:

A simple synth based on a sawtooth wave filtered by a resonant lowpass. dubDub is a standard Faust function.

dubDub(freq,ctFreq,q,gate) : _;

Where:

A simple trombone based on a lowpassed sawtooth wave. sawTrombone is a standard Faust function.

sawTrombone(att,freq,gain,gate) : _

Where:

Simplest string physical model ever based on a comb filter. combString is a standard Faust function.

combString(freq,res,gate) : _;

Where:

A simple drum using additive synthesis. additiveDrum is a standard Faust function.

additiveDrum(freq,freqRatio,gain,harmDec,att,rel,gate) : _

Where:

freq: the resonance frequency of the drum
freqRatio: a list of ratio to choose the frequency of the mode in function of freq e.g.(1 1.2 1.5 ...). The first element should always
gain: the gain of each mode as a list (1 0.9 0.8 ...). The first element
harmDec: harmonic decay ratio (0-1): configure the speed at which
att: attack duration in second
rel: release duration in second
gate: trigger signal (0 or 1)

An FM synthesizer with an arbitrary number of modulators connected as a sequence. fm is a standard Faust function.

freqs = (300,400,...);
indices = (20,...);
fm(freqs,indices) : _

Where:

freqs: a list of frequencies where the first one is the frequency of the carrier
indices: the indices of modulation (Nfreqs-1)
