AudioFormat

Enum AudioFormat 

Source
#[non_exhaustive]
pub enum AudioFormat { U8, S16, S32, F32, U8Planar, S16Planar, S32Planar, F32Planar, }
Expand description

Raw PCM sample format.

Mirrors the WebCodecs AudioData.format enum so callers can pass microphone or speaker buffers across the FFI boundary unchanged.

Interleaved variants pack samples as [c0_s0, c1_s0, c0_s1, c1_s1, ...]. Planar variants pack as [c0_s0, c0_s1, ..., c1_s0, c1_s1, ...].

See https://developer.mozilla.org/en-US/docs/Web/API/AudioData/format.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

U8

§

S16

§

S32

§

F32

Default: matches libopus’s native interleaved layout.

U8Planar

§

S16Planar

§

F32Planar

Implementations§

Source§

impl AudioFormat

Source

pub fn bytes_per_sample(self) -> usize

Bytes used per single-channel sample.

Source

pub fn is_planar(self) -> bool

Whether channels are stored planar (each channel contiguous) rather than interleaved.

Source

pub fn is_float(self) -> bool

Whether the underlying sample type is floating-point.

Source

pub fn as_interleaved_f32<'a>( self, data: &'a [u8], channels: u32, ) -> Result<Cow<'a, [f32]>, AudioError>

Convert a raw PCM buffer in this format to interleaved f32 in [-1.0, 1.0].

Returns a Cow::Borrowed when the input is already interleaved f32 (and the byte buffer is aligned), avoiding an allocation. Otherwise returns a Cow::Owned holding the converted samples.

Source

pub fn from_interleaved_f32( self, samples: &[f32], channels: u32, ) -> Result<Vec<u8>, AudioError>

Convert interleaved f32 PCM to this format’s raw byte representation. Returns owned bytes; integer formats clamp out-of-range samples rather than wrapping.
