Available on crate feature dep_kira only.
Expand description

Configures a compressor.

Fields§

§threshold: Value<f64>

The volume above which volume will start to be decreased (in decibels).

§ratio: Value<f64>

How much the signal will be compressed.

A ratio of 2.0 (or 2 to 1) means an increase of 3dB will become an increase of 1.5dB. Ratios between 0.0 and 1.0 will actually expand the audio.

§attack_duration: Value<Duration>

How much time it takes for the volume attenuation to ramp up once the input volume exceeds the threshold.

§release_duration: Value<Duration>

How much time it takes for the volume attenuation to relax once the input volume dips below the threshold.

§makeup_gain: Value<Decibels>

The amount to change the volume after processing (in dB).

This can be used to compensate for the decrease in volume resulting from compression. This is only applied to the wet signal, nto the dry signal.

§mix: Value<Mix>

How much dry (unprocessed) signal should be blended with the wet (processed) signal.

Implementations§

§

impl CompressorBuilder

pub fn new() -> CompressorBuilder

Creates a new CompressorBuilder with the default settings.

pub fn threshold(self, threshold: impl Into<Value<f64>>) -> CompressorBuilder

Sets the volume above which volume will start to be decreased (in decibels).

pub fn ratio(self, ratio: impl Into<Value<f64>>) -> CompressorBuilder

Sets how much the signal will be compressed.

A ratio of 2.0 (or 2 to 1) means an increase of 3dB will become an increase of 1.5dB. Ratios between 0.0 and 1.0 will actually expand the audio.

pub fn attack_duration( self, attack_duration: impl Into<Value<Duration>>, ) -> CompressorBuilder

Sets how much time it takes for the volume attenuation to ramp up once the input volume exceeds the threshold.

pub fn release_duration( self, release_duration: impl Into<Value<Duration>>, ) -> CompressorBuilder

Sets how much time it takes for the volume attenuation to relax once the input volume dips below the threshold.

pub fn makeup_gain( self, makeup_gain: impl Into<Value<Decibels>>, ) -> CompressorBuilder

Sets the amount to change the volume after processing (in decibels).

This can be used to compensate for the decrease in volume resulting from compression. This is only applied to the wet signal, nto the dry signal.

pub fn mix(self, mix: impl Into<Value<Mix>>) -> CompressorBuilder

Sets how much dry (unprocessed) signal should be blended with the wet (processed) signal.
