Functions | |
SPAN_DECLARE (int) plc_rx(plc_state_t *s | |
Release a V.8 context. | |
SPAN_DECLARE (plc_state_t *) plc_init(plc_state_t *s) | |
Initialise a PLC context. | |
Variables | |
int16_t | amp [] |
int16_t int | len |
|
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. |
|
Maximum allowed pitch (200 Hz) |
|
Minimum allowed pitch (66 Hz) |
|
Maximum pitch OLA window |
|
Initialise a PLC context. Initialise a packet loss concealer context.
|
|
Release a V.8 context. Process a block of received audio samples for PLC.
