ISP_IFPTRACK

Pitch track based on instantaneous frequency.

Contents

Syntax

[p,m,S] = ifptrack(d,w,sr,fminl,fminu,fmaxl,fmaxu)

Description

Track pitch based on instantaneous frequency. It looks for adjacent bins with same inst freq.

Input

d:
Input waveform.
w:
STFT DFT length (window is half, hop is 1/4).
sr:
Sample rate.
fminl, fmaxu, fmaxl, fmaxu:
Define ramps at edge of sensitivity.

Output

p:
Tracked pitch frequencies.
m:
Tracked pitch magnitudes.
S:
The underlying complex STFT.
