Struct AudioFrame 

pub struct AudioFrame {
    pub data: Bytes,
    pub sample_rate: u32,
    pub channels: u8,
    pub duration_ms: u32,
}

Available on crate feature audio only.

The canonical audio buffer — raw PCM-16 LE samples with metadata.

All adk-audio components produce and consume AudioFrame values, eliminating format negotiation between pipeline stages.

Example

use adk_audio::AudioFrame;

let silence = AudioFrame::silence(16000, 1, 100);
assert_eq!(silence.sample_rate, 16000);
assert_eq!(silence.channels, 1);
assert_eq!(silence.duration_ms, 100);

Fields

data: Bytes

Raw PCM-16 LE sample data.

sample_rate: u32

Sample rate in Hz (e.g. 16000, 24000, 44100, 48000).

channels: u8

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

duration_ms: u32

Duration in milliseconds, computed from data length.

Implementations

impl AudioFrame

pub fn new(data: impl Into<Bytes>, sample_rate: u32, channels: u8) -> AudioFrame

Create a new AudioFrame from raw PCM-16 LE data.

Duration is computed automatically from the data length, sample rate, and channel count.

pub fn samples(&self) -> &[i16]

View the raw data as a slice of i16 samples.

pub fn silence(sample_rate: u32, channels: u8, duration_ms: u32) -> AudioFrame

Create a silent AudioFrame of the given duration.

Trait Implementations

impl Clone for AudioFrame

fn clone(&self) -> AudioFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioFrame

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

Formats the value using the given formatter.

impl PartialEq for AudioFrame

fn eq(&self, other: &AudioFrame) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
