Struct EnvelopeAutomaton 

pub struct EnvelopeAutomaton { /* private fields */ }

An envelope automaton that generates time-varying control signals.

The envelope progresses through stages (Attack, Decay, Sustain, Release, etc.) and outputs a value that can be mapped to a parameter. The stage curve controls the shape: 1.0 = linear, >1.0 = exponential, <1.0 = logarithmic.

Implementations

impl EnvelopeAutomaton

pub fn adsr( name: &str, attack: f64, decay: f64, sustain: f64, release: f64, ) -> Self

Create a new ADSR envelope.

pub fn ar(name: &str, attack: f64, release: f64) -> Self

Create a new AR envelope (suitable for percussion).

pub fn asr(name: &str, attack: f64, sustain: f64, release: f64) -> Self

Create a new ASR envelope (suitable for organ sounds).

pub fn ahdsr( name: &str, attack: f64, hold: f64, decay: f64, sustain: f64, release: f64, ) -> Self

Create a new AHDSR envelope with an additional hold stage.

pub fn with_curve(self, curve: f64) -> Self

Set the stage curve exponent (1.0 = linear).

pub fn with_range(self, range: Range) -> Self

Set the output range.
