Struct AudioFrame 

pub struct AudioFrame {
    pub samples: Vec<u8>,
    pub sample_count: usize,
    pub sample_rate: u32,
    pub channels: usize,
    pub format: SampleFormat,
    pub pts: Option<i64>,
    pub duration: Option<u64>,
}

An audio frame containing decoded samples.

Audio frames store PCM samples in interleaved format for multi-channel audio. For example, stereo audio is stored as [L0, R0, L1, R1, L2, R2, …].

Fields

samples: Vec<u8>

Raw sample data (interleaved if multi-channel)

sample_count: usize

Number of samples per channel

sample_rate: u32

Sample rate in Hz (e.g., 48000 for 48kHz)

channels: usize

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

format: SampleFormat

Sample format

pts: Option<i64>

Presentation timestamp in sample units

duration: Option<u64>

Duration in sample units

Implementations

impl AudioFrame

pub fn new( samples: Vec<u8>, sample_count: usize, sample_rate: u32, channels: usize, format: SampleFormat, ) -> Self

Creates a new audio frame.

Arguments

• samples - Raw sample data (interleaved if multi-channel)
• sample_count - Number of samples per channel
• sample_rate - Sample rate in Hz
• channels - Number of channels
• format - Sample format

pub fn with_timing( samples: Vec<u8>, sample_count: usize, sample_rate: u32, channels: usize, format: SampleFormat, pts: i64, duration: u64, ) -> Self

Creates a new audio frame with timing information.

pub const fn total_samples(&self) -> usize

Returns the total number of samples (all channels combined).

pub fn byte_size(&self) -> usize

Returns the size in bytes of the audio data.

pub fn duration_seconds(&self) -> f64

Returns the duration in seconds.

pub fn to_f32(&self) -> CodecResult<Vec<f32>>

Converts bytes to f32 and returns a new Vec.

pub fn to_i16(&self) -> CodecResult<Vec<i16>>

Converts bytes to i16 and returns a new Vec.

Trait Implementations

impl Clone for AudioFrame

fn clone(&self) -> AudioFrame
