Struct AudioTranscodeConfig 

pub struct AudioTranscodeConfig {
    pub input_codec: String,
    pub output_codec: String,
    pub bitrate_kbps: u32,
    pub sample_rate: u32,
    pub channels: u8,
    pub normalize: bool,
    pub target_lufs: f64,
}

Configuration for an audio transcode operation.

Fields

input_codec: String

Name of the input audio codec (e.g., "aac", "flac").

output_codec: String

Name of the output audio codec (e.g., "opus", "aac").

bitrate_kbps: u32

Target bitrate in kilobits per second. Ignored for lossless codecs.

sample_rate: u32

Output sample rate in Hz (e.g., 48000).

channels: u8

Number of output channels (1 = mono, 2 = stereo, 6 = 5.1, etc.).

normalize: bool

Whether to apply loudness normalisation.

target_lufs: f64

Target loudness in LUFS for normalisation (e.g., -23.0 for EBU R128).

Implementations

impl AudioTranscodeConfig

pub fn new( input_codec: impl Into<String>, output_codec: impl Into<String>, bitrate_kbps: u32, sample_rate: u32, channels: u8, ) -> Self

Creates a new config with the given codecs and basic parameters.

pub fn aac_stereo_256k() -> Self

Returns a config for AAC stereo at 256 kbps / 48 kHz.

pub fn opus_stereo_128k() -> Self

Returns a config for Opus stereo at 128 kbps / 48 kHz.

pub fn flac_lossless() -> Self

Returns a config for FLAC lossless stereo at 48 kHz.

pub fn with_normalization(self, target_lufs: f64) -> Self

Enables loudness normalisation with the given LUFS target.

pub fn is_lossless_output(&self) -> bool

Returns true if the output codec is lossless.

pub fn is_valid(&self) -> bool

Returns true if the configuration is considered valid.

A valid config has a non-empty output codec, a positive sample rate, and at least one channel.

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

Performs copy-assignment from source.

impl Debug for AudioTranscodeConfig

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