Struct AudioChunk 

pub struct AudioChunk {
    format: AudioFormat,
    samples: Vec<f32>,
    pts: MediaTime,
    duration: MediaDuration,
}

One timestamped chunk of normalized f32 audio.

Sample buffer is interleaved (planar-per-frame): [L₀, R₀, L₁, R₁, …] for stereo. Mono is [s₀, s₁, …]. Duration is derived from samples.len() / channels / sample_rate.

Fields

format: AudioFormat

samples: Vec<f32>

pts: MediaTime

duration: MediaDuration

Implementations

impl AudioChunk

pub fn new( format: AudioFormat, samples: Vec<f32>, pts: MediaTime, ) -> Result<Self, AudioChunkError>

Validate + construct. Fails when channel count is zero, sample rate is zero, or samples.len() isn’t a multiple of channels.

pub fn format(&self) -> AudioFormat

Format of the carried samples.

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

Borrow the normalized f32 sample buffer.

pub fn frame_count(&self) -> usize

Number of frames (samples-per-channel) in the buffer.

pub fn pts(&self) -> MediaTime

Presentation timestamp — when this chunk’s first sample occurs on the media timeline.

pub fn duration(&self) -> MediaDuration

Derived duration of the chunk.

pub fn peak(&self) -> f32

Convenience: peak |sample| over the buffer. Used by histogram quantization (M-MEDIA.8) and capture-side regression checks.

pub fn rms(&self) -> f32

Convenience: root-mean-square over the buffer. Used by histogram quantization.

Trait Implementations

impl Clone for AudioChunk

fn clone(&self) -> AudioChunk

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AudioChunk

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AudioChunk

fn eq(&self, other: &AudioChunk) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
