| #define CORRELATION_SPAN 160 |
The length over which the AMDF function looks for similarity (20 ms)
| #define PLC_HISTORY_LEN (CORRELATION_SPAN + PLC_PITCH_MIN) |
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.
| #define PLC_PITCH_MAX 40 |
Maximum allowed pitch (200 Hz)
| #define PLC_PITCH_MIN 120 |
Minimum allowed pitch (66 Hz)
| #define PLC_PITCH_OVERLAP_MAX (PLC_PITCH_MIN >> 2) |
Maximum pitch OLA window
