Struct FileAudioSource 

pub struct FileAudioSource { /* private fields */ }

Test AudioSource that replays a fixture WAV in fixed-size chunks.

Samples are converted to f32 in [-1.0, 1.0] regardless of the fixture’s bit depth, so a single fixture can stand in for any capture-side input rate the pipeline needs to exercise.

Implementations

impl FileAudioSource

pub fn from_path(path: impl AsRef<Path>, chunk_frames: usize) -> Result<Self>

Loads a WAV file and prepares it for chunked playback.

chunk_frames is the number of frames (not samples) returned per AudioSource::next_chunk call — i.e. for stereo at chunk_frames = 1024, each chunk contains 2048 interleaved samples.

pub fn from_samples( samples: Vec<f32>, sample_rate: u32, channels: u16, chunk_frames: usize, ) -> Self

Builds a fixture source directly from an in-memory sample buffer. Useful for synthesising test signals (sine waves, silence, …) without hitting disk.

Trait Implementations

impl AudioSource for FileAudioSource

fn next_chunk(&mut self) -> Option<Vec<f32>>

Returns the next chunk of interleaved samples, or None when the source is exhausted.

fn sample_rate(&self) -> u32

The source’s sample rate in Hz.

fn channels(&self) -> u16

Channel count (1 = mono, 2 = stereo, …).
