Struct RmsEnvelopeFollower 

pub struct RmsEnvelopeFollower { /* private fields */ }

RMS envelope follower: a single-pole exponential moving average of instantaneous power, reported as an RMS level.

Implementations

impl RmsEnvelopeFollower

pub fn new(time_constant_samples: f32) -> Self

time_constant_samples: the time constant, in samples, of the underlying power averaging filter.

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

Processes one input sample and returns the updated RMS envelope value.

pub fn reset(&mut self)

Resets the running mean-square to zero.
