Struct Envelope 

pub struct Envelope {
    pub attack_secs: f32,
    pub release_secs: f32,
    pub hold_secs: f32,
    /* private fields */
}

Amplitude envelope follower with attack, hold, and release stages.

Fields

attack_secs: f32

Attack time constant in seconds.

release_secs: f32

Release time constant in seconds.

hold_secs: f32

Hold time in seconds before release begins.

Implementations

impl Envelope

pub fn new( attack_secs: f32, release_secs: f32, hold_secs: f32, sample_rate: f32, ) -> Self

pub fn process(&mut self, input: f32) -> f32

Process one sample, return the envelope level.

pub fn process_buffer(&mut self, buf: &[f32]) -> Vec<f32>

Process a buffer, returning the envelope for each sample.

pub fn reset(&mut self)

Reset the envelope state.

pub fn level(&self) -> f32

Current envelope level.
