Struct Audio 

pub struct Audio {
    pub rate: u32,
    pub channels: Vec<Vec<f32>>,
}

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

Fields

rate: u32

channels: Vec<Vec<f32>>

Implementations

impl Audio

pub fn silence(rate: u32, channels: usize, frames: usize) -> Self

channels channels of frames samples of silence.

pub fn mono(rate: u32, samples: Vec<f32>) -> Self

pub fn frames(&self) -> usize

Samples per channel.

pub fn seconds(&self) -> f64

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

The average of all channels.

pub fn to_stereo(&self) -> Self

Mono is copied to both sides; more than two channels fold down to the first two.

pub fn gain_db(&mut self, db: f64)

Multiplies every sample by 10^(db/20).

pub fn mix_in(&mut self, other: &Audio, at: usize)

Adds other (same channel count) into self starting at frame at, growing as needed.

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

Pads (with silence) or truncates to frames.

pub fn read_wav(path: &Path) -> Result<Self>

Reads a WAV (PCM 8/16/24/32-bit or 32-bit float).

pub fn write_wav(&self, path: &Path) -> Result<()>

Writes a 32-bit float WAV.

impl Debug for Audio

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

Formats the value using the given formatter.

impl Default for Audio

fn default() -> Self

Returns the “default value” for a type.
