Implementations

impl WavFile

pub fn parse(data: &[u8]) -> Result<WavFile, KernelError>

Parse a WAV file from a byte buffer

Validates the RIFF/WAVE header, locates the “fmt “ and “data” chunks, and extracts metadata.

pub fn sample_data<'a>(&self, source: &'a [u8]) -> &'a [u8]

Get a reference to the PCM data within the source buffer

pub fn to_audio_config(&self) -> AudioConfig

Convert this WAV file’s format info to an AudioConfig

pub fn duration_ms(&self) -> u64

Calculate the duration of the audio in milliseconds

pub fn total_samples(&self) -> usize

Calculate the total number of samples (all channels)

Trait Implementations

impl Clone for WavFile

fn clone(&self) -> WavFile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WavFile

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

Formats the value using the given formatter.
