music.IteratorSynth

class music.IteratorSynth(**statevars)

Bases: CanonicalSynth

A synthesizer that iterates through arbitrary lists of variables.

Inherits from CanonicalSynth.

It adds no attributes of its own.

Examples

>>> isynth = M.IteratorSynth()
>>> isynth.fundamental_frequency_sequence = [220, 400, 100, 500]
>>> isynth.duration_sequence = [2, 1, 1.5]
>>> isynth.vibrato_frequency_sequence = [3, 6.5, 10]
>>> sounds = []
>>> for i in range(300):
...     sounds += [isynth.renderIterate(tremolo_frequency=.2*i)]
>>> import music.core.io
>>> music.core.io.write_wav_mono(M.H(*sounds), "./example.wav")

__init__(**statevars)

Initializes the synthesizer with given state variables.

Parameters:

**statevarsdict

Arbitrary keyword arguments for state variables.

Methods

__init__(**statevars)	Initializes the synthesizer with given state variables.
absorbState(**statevars)	Absorb state variables.
adsrApply(audio_vec)	Apply ADSR envelope to the audio vector.
adsrSetup([A, D, S, R, render_note, adsr_method])	Setup ADSR parameters.
iterateElements()	Iterates through the sequences of state variables.
rawRender(**statevars)	Render the sound without applying ADSR.
render(**statevars)	Render a note with given parameters.
render2(**statevars)	Render the sound and apply ADSR.
renderIterate(**statevars)	Renders a sound iteration with the given state variables.
synthSetup([table, vibrato_table, ...])	Setup synth engine.
tremoloEnvelope([sonic_vector])	Calculate the tremolo envelope.
