Macros¶

#define OPUS_SET_GAIN(x)
Configures decoder gain adjustment. #define OPUS_GET_GAIN(x)
Gets the decoder's configured gain adjustment. #define OPUS_GET_LAST_PACKET_DURATION(x)
Gets the duration (in samples) of the last packet successfully decoded or concealed. #define OPUS_GET_PITCH(x)
Gets the pitch of the last decoded frame, if available. #define OPUS_SET_OSCE_BWE(x)
Enables blind bandwidth extension for wideband signals if decoding sampling rate is 48 kHz. #define OPUS_GET_OSCE_BWE(x)
Gets blind bandwidth extension flag for wideband signals if decoding sampling rate is 48 kHz. #define OPUS_SET_IGNORE_EXTENSIONS(x)
If set to 1, the decoder will ignore all extensions found in the padding area (does not affect DRED, which is decoded separately). #define OPUS_GET_IGNORE_EXTENSIONS(x)
Gets whether the decoder is ignoring extensions.

#define OPUS_GET_GAIN( x)¶

Gets the decoder's configured gain adjustment.

Parameters

#define OPUS_GET_IGNORE_EXTENSIONS( x)¶

Gets whether the decoder is ignoring extensions.

#define OPUS_GET_LAST_PACKET_DURATION( x)¶

Gets the duration (in samples) of the last packet successfully decoded or concealed.

Parameters

#define OPUS_GET_OSCE_BWE( x)¶

Gets blind bandwidth extension flag for wideband signals if decoding sampling rate is 48 kHz.

Parameters

#define OPUS_GET_PITCH( x)¶

Gets the pitch of the last decoded frame, if available. This can be used for any post-processing algorithm requiring the use of pitch, e.g. time stretching/shortening. If the last frame was not voiced, or if the pitch was not coded in the frame, then zero is returned.

This CTL is only implemented for decoder instances.

Parameters

#define OPUS_SET_GAIN( x)¶

Configures decoder gain adjustment. Scales the decoded output by a factor specified in Q8 dB units. This has a maximum range of -32768 to 32767 inclusive, and returns OPUS_BAD_ARG otherwise. The default is zero indicating no adjustment. This setting survives decoder reset.

gain = pow(10, x/(20.0*256))

Parameters

#define OPUS_SET_IGNORE_EXTENSIONS( x)¶

If set to 1, the decoder will ignore all extensions found in the padding area (does not affect DRED, which is decoded separately).

#define OPUS_SET_OSCE_BWE( x)¶

Enables blind bandwidth extension for wideband signals if decoding sampling rate is 48 kHz.
