Struct AudioParams 

pub struct AudioParams {
    pub sample_rate: u32,
    pub channels: u16,
    pub sample_format: SampleFormat,
    pub bitrate_bps: Option<u64>,
    pub frame_size: Option<u32>,
    pub loudness_lufs: Option<f32>,
}

Audio stream encoding / decoding parameters.

Fields

sample_rate: u32

Sample rate in Hz (e.g. 48_000 for broadcast audio).

channels: u16

Number of audio channels (1 = mono, 2 = stereo, 6 = 5.1, …).

sample_format: SampleFormat

Sample format (default: SampleFormat::F32).

bitrate_bps: Option<u64>

Target or measured peak bitrate in bits per second, if known.

frame_size: Option<u32>

Frame size (samples per channel per frame), if fixed by the codec.

For example, Opus uses 20 ms frames at 48 kHz → 960 samples.

loudness_lufs: Option<f32>

Normalisation loudness target in LUFS, if known (e.g. −23 LUFS for EBU R128).

Implementations

impl AudioParams

pub fn new(sample_rate: u32, channels: u16) -> Self

Creates minimal AudioParams with sample_rate and channels.

Defaults: sample_format = SampleFormat::F32, other fields None.

pub fn is_valid(&self) -> bool

Returns true if the parameters are logically valid.

pub fn frame_duration_secs(&self) -> Option<f64>

Returns the duration of a single frame in seconds, or None if no fixed frame size is set.

pub fn with_sample_format(self, fmt: SampleFormat) -> Self

Builder-style setter for sample format.

pub fn with_bitrate(self, bps: u64) -> Self

Builder-style setter for bitrate.

pub fn with_frame_size(self, samples: u32) -> Self

Builder-style setter for frame size.

pub fn with_loudness(self, lufs: f32) -> Self

Builder-style setter for loudness target.

Trait Implementations

impl Clone for AudioParams

fn clone(&self) -> AudioParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioParams

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

Formats the value using the given formatter.

impl PartialEq for AudioParams

fn eq(&self, other: &AudioParams) -> 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.
