Struct Adsr 

pub struct Adsr {
    pub node: GraphNode,
    /* private fields */
}

An ADSR node that will create an envelope to modulate the amplitude of its input

Fields

node: GraphNode

The node that can be routed into the audio graph

Implementations

impl Adsr

pub fn new( context: &dyn Context, channel_count: usize, sample_rate: usize, ) -> Self

Create a new ADSR node

pub fn note_on_at_time(&mut self, time: Timestamp)

Trigger a note on at a particular time

pub fn note_off_at_time(&mut self, time: Timestamp)

Trigger a note off at a particular time

pub fn set_attack_time(&mut self, attack_time: Duration)

Set the attack time

This is the time from the note on until the gain reaches unity

pub fn set_decay_time(&mut self, decay_time: Duration)

Set the decay time

This is the time after the end of the attack time to reach the steady-state sustain level

pub fn set_sustain_level(&mut self, sustain_level: Level)

Set the sustain level

This is the level that will be sustained after the attack and decay phase until a note off

pub fn set_release_time(&mut self, release_time: Duration)

Set the release time

This is the time after a note off until gain of 0 is reached

pub fn set_adsr( &mut self, attack_time: Duration, decay_time: Duration, sustain_level: Level, release_time: Duration, )

Convenience method to set the attack, decay, sustain, and release in one go
