Functions | |
int | plc_rx (plc_state_t *s, int16_t amp[], int len) |
Process a block of received audio samples for PLC. | |
int | plc_fillin (plc_state_t *s, int16_t amp[], int len) |
Fill-in a block of missing audio samples. | |
plc_state_t * | plc_init (plc_state_t *s) |

int | plc_free (plc_state_t *s) |
|
The length over which the AMDF function looks for similarity (20 ms) |
|
History buffer length. The buffer much also be at leat 1.25 times PLC_PITCH_MIN, but that is much smaller than the buffer needs to be for the pitch assessment. |

Minimum allowed pitch (66 Hz) |
|
Maximum pitch OLA window |
