pub fn set_sample_rate(&self, sample_rate: f32)

Set the envelope sample rate, required before playback

pub fn set_attack(&self, duration: Duration)

Set the envelope sample rate, required before playback

pub fn set_decay(&self, duration: Duration)

Set the envelope decay time

pub fn set_sustain(&self, sustain: f32)

Set the envelope sustain time

pub fn set_release(&self, duration: Duration)

Set the envelope release time

pub fn volume(&self) -> f32

Get the current volume multiplier

pub fn tick(&self)

Update the envelope, pushing its state forwards by 1 sample

pub fn note_on(&self)

Trigger the envelope by setting its stage to the Attack phase. Does not change the current volume, only the stage.
