| #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_GET_GAIN | ( | x | ) |
Gets the decoder's configured gain adjustment.
| [out] | x | opus_int32 *: Amount to scale PCM signal by in Q8 dB units. |
| #define OPUS_GET_LAST_PACKET_DURATION | ( | x | ) |
Gets the duration (in samples) of the last packet successfully decoded or concealed.
| [out] | x | opus_int32 *: Number of samples (at current sampling rate). |
| #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.
| [out] | x | opus_int32 *: pitch period at 48 kHz (or 0 if not available) |
| #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))
| [in] | x | opus_int32: Amount to scale PCM signal by in Q8 dB units. |
