Struct SampleBuffer 

pub struct SampleBuffer {
    pub samples: Vec<f32>,
    pub channels: u16,
    pub sample_rate: u32,
    pub frames: usize,
    pub path: String,
}

A decoded audio buffer stored as interleaved f32 samples.

Fields

samples: Vec<f32>

Interleaved samples (mono or stereo).

channels: u16

Number of channels (1=mono, 2=stereo).

sample_rate: u32

Original sample rate in Hz.

frames: usize

Total number of frames (samples / channels).

path: String

File path this was loaded from.

Implementations

impl SampleBuffer

pub fn load_wav(path: &Path) -> Result<Self, BufferError>

Load a WAV file into memory as f32 samples.

pub fn sample_at(&self, frame: f64) -> f32

Get a mono sample at a given frame position (linear interpolation). If stereo, returns the average of both channels.

pub fn load_wav_reader<R: Read + Seek>(reader: R) -> Result<Self, BufferError>

Load a WAV from any Read + Seek source (e.g. an in-memory Cursor<&[u8]>). This is used by the CLAP plugin to decode audio that was embedded at build time.

pub fn duration_secs(&self) -> f32

Duration in seconds.

Trait Implementations

impl Clone for SampleBuffer

fn clone(&self) -> SampleBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SampleBuffer

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

Formats the value using the given formatter.
