|
|
=====================================
|
||
|
|
|
||
|
|
Predefined variables :
|
||
|
|
- P = number of partials
|
||
|
|
- T = number of frames
|
||
|
|
- p = current partial index [0, nPartials - 1] (av order)
|
||
|
|
- t = current frame index [0, nFrames - 1]
|
||
|
|
- a, amin, amax, amean = amplitude
|
||
|
|
- f, fmin, fmax, fmean = frequency
|
||
|
|
- h, hmin, hmax, hmean = phase
|
||
|
|
- v, vmin, vmax, vmean = selected magnitude (= a or f or h)
|
||
|
|
|
||
|
|
Predefined functions :
|
||
|
|
- A(p,t) = amplitude
|
||
|
|
- F(p,t) = frequency
|
||
|
|
- H(p,t) = phase
|
||
|
|
- V(p,t) = selected magnitude (= a or f or h)
|
||
|
|
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
- frequency-flatten spectrogram around F(pr,tr) reference frequency
|
||
|
|
f = f*F(pr,tr)/F(pr,t)
|
||
|
|
|
||
|
|
Ex: xj220b.ats : f = f*F(38,42)/F(38,t)
