Struct FastLowpassNode 

pub struct FastLowpassNode<const CHANNELS: usize> {
    pub cutoff_hz: f32,
    pub enabled: bool,
    pub smooth_seconds: f32,
    pub coeff_update_factor: CoeffUpdateFactor,
}

A simple single-pole IIR lowpass filter that is computationally efficient

Fields

cutoff_hz: f32

The cutoff frequency in hertz in the range [20.0, 20480.0].

enabled: bool

Whether or not this node is enabled.

smooth_seconds: f32

The time in seconds of the internal smoothing filter.

By default this is set to 0.015 (15ms).

coeff_update_factor: CoeffUpdateFactor

An exponent representing the rate at which DSP coefficients are updated when parameters are being smoothed.

Smaller values will produce less “stair-stepping” artifacts, but will also consume more CPU.

The resulting number of frames (samples in a single channel of audio) that will elapse between each update is calculated as 2^coeff_update_factor.

By default this is set to 5.
