Struct Gain 

pub struct Gain(/* private fields */);

Relative loudness adjustment for audio clips.

Use Gain with PcmClipBuf::with_gain to make a clip louder or quieter before playback.

with_gain is intended for const clip definitions, so the adjusted samples are precomputed at compile time with no extra runtime work.

You can set gain by percent or by dB:

• Gain::percent where 100 means unchanged and values above 100 are louder.
• Gain::db where positive dB is louder and negative dB is quieter.

This is different from Volume used by max_volume, initial_volume, and set_volume, which set the absolute playback loudness behavior for the whole player.

See the audio_player module documentation for usage examples.

Implementations

impl Gain

pub const MUTE: Self

Silence.

pub const fn percent(percent: u16) -> Self

Creates a gain from percentage.

100 is unity gain. Values above 100 boost the signal.

See the audio_player module documentation for usage examples.

pub const fn db(db: i8) -> Self

Creates gain from dB with a bounded boost range.

Values above +12 dB clamp to +12 dB. Values below -96 dB clamp to -96 dB.

See PcmClipBuf::with_gain for usage.
