scisonify.core.envelope.EnvelopeADSR

class scisonify.core.envelope.EnvelopeADSR(attack_length=0.2, decay_length=0.1, release_length=0.2, note_length=1.0, start_amplitude=0.0, sustian_amplitude=0.8)

Attack-Decay-Sustain-Release Envelope Implementation, adapted from the C++ implementation by javidx9 (https://www.youtube.com/watch?v=OSCzKOqtgcA)

Parameters

attack_length: optional, float: Duration of “attack”
decay_length: optional, float: Duration of “decay”
release_length: optional, float: Duration of “release”
note_length: optional, float: The total length of a note
start_amplitude: optional, float: Initial amplitude for a note
sustian_amplitude: optional, float: Sustain amplitude for a note

__init__(attack_length=0.2, decay_length=0.1, release_length=0.2, note_length=1.0, start_amplitude=0.0, sustian_amplitude=0.8)

Methods

`__init__`([attack_length, decay_length, ...])
`get_amplitude`(time)	Returns the envelope amplitude at a given time step
`get_amplitudes`(times)	Returns all the amplitudes for an array of discrete times.
