OPUS_GET_VOICE_RATIO

#define OPUS_GET_VOICE_RATIO

(

x

)

Gets the encoder's configured voice ratio value,

OPUS_SET_VOICE_RATIO

Parameters

[out]

x

int*: Voice percentage in the range 0-100, inclusive.

OPUS_GET_VOICE_RATIO_REQUEST

#define OPUS_GET_VOICE_RATIO_REQUEST   11019

OPUS_SET_FORCE_MODE

OPUS_SET_FORCE_MODE_REQUEST, __opus_check_int(x)

OPUS_SET_FORCE_MODE_REQUEST

#define OPUS_SET_FORCE_MODE_REQUEST   11002

OPUS_SET_VOICE_RATIO

#define OPUS_SET_VOICE_RATIO

(

x

)

Configures the encoder's expected percentage of voice opposed to music or other signals.

Note

This interface is currently more aspiration than actuality. It's ultimately expected to bias an automatic signal classifier, but it currently just shifts the static bitrate to mode mapping around a little bit.

Parameters

[in]

x

int: Voice percentage in the range 0-100, inclusive.

OPUS_SET_VOICE_RATIO_REQUEST

#define OPUS_SET_VOICE_RATIO_REQUEST   11018
