Function audio_settings_jni_payload 

Source 
pub fn audio_settings_jni_payload(
    settings: &AudioSettings,
) -> Result<String, Error>
Expand description

Serialise AudioSettings into the JSON payload handed to the Android player over JNI.

Sanitises first (crossfade clamped, band vector normalised) so a malformed vector can never reach the Kotlin parser. JSON is used rather than a wide JNI signature so that adding a field does not change the method signature — the same approach load() already uses for subtitles.

The emitted keys are camelCase (serde) and volumeLevel is lowercase; the Kotlin side matches on those literals. Both are pinned by tests.
