Struct PeakEnvelopeFollower 

pub struct PeakEnvelopeFollower { /* private fields */ }

Peak envelope follower with independent attack/release time constants, as used for audio dynamics processing (compressors, limiters, VU-style level meters).

Implementations

impl PeakEnvelopeFollower

pub fn new(attack_samples: f32, release_samples: f32) -> Self

attack_samples / release_samples: the time constant, in samples, for the envelope to rise / fall 1 - 1/e (~63%) of the way to a step change in input level.

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

Processes one input sample and returns the updated envelope value.

pub fn reset(&mut self)

Resets the envelope to zero.
