synths.lib
This library contains a collection of synthesizers. Its official
prefix is sy.
(sy.)popFilterPerc
A simple percussion instrument based on a "popped" resonant bandpass filter.
popFilterPerc is a standard Faust function.
Usage
popFilterDrum(freq,q,gate) : _
Where:
- freq: the resonance frequency of the instrument
- q: the q of the res filter (typically, 5 is a good value)
- gate: the trigger signal (0 or 1)
(sy.)dubDub
A simple synth based on a sawtooth wave filtered by a resonant lowpass.
dubDub is a standard Faust function.
Usage
dubDub(freq,ctFreq,q,gate) : _
Where:
- freq: frequency of the sawtooth
- ctFreq: cutoff frequency of the filter
- q: Q of the filter
- gate: the trigger signal (0 or 1)
(sy.)sawTrombone
A simple trombone based on a lowpassed sawtooth wave.
sawTrombone is a standard Faust function.
Usage
sawTrombone(att,freq,gain,gate) : _
Where:
- att: exponential attack duration in s (typically 0.01)
- freq: the frequency
- gain: the gain (0-1)
- gate: the gate (0 or 1)
(sy.)combString
Simplest string physical model ever based on a comb filter.
combString is a standard Faust function.
Usage
combString(freq,res,gate) : _
Where:
- freq: the frequency of the string
- res: string T60 (resonance time) in second
- gate: trigger signal (0 or 1)
(sy.)additiveDrum
A simple drum using additive synthesis.
additiveDrum is a standard Faust function.
Usage
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- freqe.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)
(sy.)fm
An FM synthesizer with an arbitrary number of modulators connected as a sequence.
fm is a standard Faust function.
Usage
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)
