Struct EnvelopeFollower 

pub struct EnvelopeFollower { /* private fields */ }

Attack-release envelope follower producing a smooth modulation signal.

Implementations

impl EnvelopeFollower

pub fn new(attack_ms: f32, release_ms: f32, sample_rate: u32) -> Self

Create a new envelope follower.

attack_ms: Time to reach ~63% of a step increase. release_ms: Time to decay to ~37% of a step decrease.

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

Process one sample (provide absolute value of input).

Returns the current envelope value. NaN/inf inputs are treated as zero to prevent permanent envelope corruption.

pub fn process_block(&mut self, samples: &[f32]) -> f32

Process a block and return the final envelope value.

Useful when you only need the envelope at block boundaries.

pub fn set_times(&mut self, attack_ms: f32, release_ms: f32, sample_rate: u32)

Update attack/release times.

pub fn reset(&mut self)

Reset envelope to zero.

pub fn current(&self) -> f32

Get current envelope value without processing.
