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.

Trait Implementations

impl Automaton for EnvelopeAutomaton

type Internal = (EnvelopeStage, f64, f64)

The automaton’s internal state, carried across step invocations.

type Action = EnvelopeAction

An optional action type driving state transitions on each step.

fn step( &self, internal: &mut Self::Internal, current: &ParamValue, time: Time, action: &Self::Action, ) -> ParamValue

Advances the automaton by one step, producing a new output value.

fn initial_internal(&self) -> Self::Internal

Returns the automaton’s initial internal state (at time zero).

fn name(&self) -> &str

Returns the human-readable name of this automaton.

fn reset(&self) -> Self::Internal

Resets the automaton to its initial internal state.

impl Clone for EnvelopeAutomaton

fn clone(&self) -> EnvelopeAutomaton

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EnvelopeAutomaton

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
