Struct ChannelMatrix 

pub struct ChannelMatrix { /* private fields */ }

Finite row-major channel mapping applied before sample quantization.

Implementations

impl ChannelMatrix

pub fn new( input_channels: usize, output_channels: usize, gains: Vec<f32>, ) -> Result<Self, PcmConversionError>

Builds a bounded row-major matrix with one row per output channel.

pub fn identity(channels: usize) -> Result<Self, PcmConversionError>

Builds an identity mapping for channels interleaved lanes.

pub fn mono_to_stereo() -> Self

Builds the canonical mono-to-stereo duplication mapping.

pub fn stereo_to_mono() -> Self

Builds an equal-amplitude stereo-to-mono downmix.

Each input is scaled by one half, so equal correlated channels retain their level without clipping solely because of the mapping.

pub fn input_channels(&self) -> usize

Returns the number of interleaved source channels.

pub fn output_channels(&self) -> usize

Returns the number of interleaved destination channels.

pub fn gains(&self) -> &[f32]

Borrows row-major output-by-input gains.
