Struct AudioBuffer 

pub struct AudioBuffer {
    pub sample_rate: u32,
    pub data: Vec<Vec<f32>>,
}

Planar f32 audio: one Vec<f32> per channel, all the same length.

Fields

sample_rate: u32

data: Vec<Vec<f32>>

Implementations

impl AudioBuffer

pub fn new(sample_rate: u32, channels: usize, frames: usize) -> Self

A silent buffer.

pub fn from_planar(sample_rate: u32, data: Vec<Vec<f32>>) -> Self

Build from planar channels. Shorter channels are zero-padded to the longest.

pub fn from_mono(sample_rate: u32, samples: Vec<f32>) -> Self

pub fn from_interleaved( sample_rate: u32, channels: usize, samples: &[f32], ) -> Self

pub fn to_interleaved(&self) -> Vec<f32>

pub fn channels(&self) -> usize

pub fn frames(&self) -> usize

pub fn duration_s(&self) -> f64

pub fn is_empty(&self) -> bool

pub fn mono_mix(&self) -> Vec<f32>

Average of all channels.

pub fn slice(&self, start: usize, end: usize) -> AudioBuffer

Frames [start, end), clamped to the buffer.

pub fn append(&mut self, other: &AudioBuffer)

Append another buffer with the same channel count (extra channels are dropped, missing ones are filled from the last channel).

pub fn peak(&self) -> f32

pub fn rms(&self) -> f32

pub fn scale(&mut self, g: f32)

Multiply every sample by g.

pub fn with_channels(&self, n: usize) -> AudioBuffer

Change the channel count: mono→N duplicates, N→mono averages, otherwise truncates or repeats the last channel.

pub fn resize(&mut self, frames: usize)

Resize every channel to frames, padding with zeros.

pub fn info(&self) -> BufferInfo
