Struct StereoMultiMixer 

pub struct StereoMultiMixer<T: Float> { /* private fields */ }

Upmix/downmix a stereo signal to an (even) multi-channel signal

When spreading out, it rotates the input by various amounts (e.g. a four-channel signal would produce (left, right, mid, side)), such that energy is preserved for each pair.

When mixing together, it uses the opposite rotations, such that upmix → downmix produces the same stereo signal (when scaled by .scaling_factor1()).

Implementations

impl<T: Float + FromPrimitive> StereoMultiMixer<T>

pub fn new(channels: usize) -> Self

Create a new mixer with the specified number of channels (must be even)

pub fn stereo_to_multi(&self, input: &[T; 2], output: &mut [T])

Convert a stereo signal to a multi-channel signal

pub fn multi_to_stereo(&self, input: &[T], output: &mut [T; 2])

Convert a multi-channel signal back to stereo

pub fn scaling_factor1(&self) -> T

Scaling factor for the downmix, if channels are phase-aligned

pub fn scaling_factor2(&self) -> T

Scaling factor for the downmix, if channels are independent
