PitchTracker
Extension
ExtensionDescription
Pitch follower with 3 different methods. Returns estimated frequency, estimated clarity (0 to 1 on kind acr and nsdf) and R0 (power of signal) Argument size must be bigger for detecting lower frequencies (At 44100 sample rate a size of 4096 is necesary for 34Hz frequency detection)
Class Methods
.kr
Arguments:
| in |
signal to get pitch from. |
| size |
size of buffer to perform autocorrelation. Must be power of two. Must be greater for detecting lower frequencies. |
| hop |
fraction of size that triggers a new analysis. |
| dfreq |
expected frequency (to accelerate analysis) only used if useef is 1. |
| thresh |
minimum level of valid peak (from 0 to 1) |
| kind |
kind of analysis, 0 ACR, 1 NSDF, 2 SDF(worst performant). |
| useef |
use dfreq value to accelerate peak searching (1) or not (0). |
| bufnum |
SndBuffer representing analysys. (-1 means no SndBuffer) |
| t_clear |
zeroes analysis buffer when is not 0. |
