Struct AudioTranscodeParams 

pub struct AudioTranscodeParams {
    pub input_layout: AudioLayout,
    pub output_layout: AudioLayout,
    pub input_sample_rate: u32,
    pub output_sample_rate: u32,
    pub target_bitrate_bps: u32,
    pub gain_linear: f32,
    pub normalise_loudness: bool,
}

Parameters that govern how a single audio stream is transcoded.

Fields

input_layout: AudioLayout

Input channel layout.

output_layout: AudioLayout

Desired output channel layout.

input_sample_rate: u32

Input sample rate in Hz.

output_sample_rate: u32

Desired output sample rate in Hz.

target_bitrate_bps: u32

Target audio bitrate in bits per second.

gain_linear: f32

Linear gain to apply during transcode (1.0 = no change).

normalise_loudness: bool

Whether to normalise loudness to EBU R128.

Implementations

impl AudioTranscodeParams

pub fn stereo() -> Self

Create default params for a stereo stream.

pub fn mono_downmix() -> Self

Create params for a mono downmix.

pub fn is_passthrough(&self) -> bool

Returns true when the output layout and sample rate match the input and no gain or loudness normalisation is applied — i.e. pure passthrough.

pub fn is_valid(&self) -> bool

Returns true if the configuration is logically valid.
