Description:
Tracks sinusoidal partial in an audio file and returns an SDIF sound description file.
- FileName : the pathname of the sound file (Aiff) to be analysed
- begin-t : begin time of analysis (s)
- end-t : end time of analysis (s)
- max-partials : the maximum number of simultaneous partials
- amp-treshold : Amplitude treshold of analysis (-120 -> 0 dB)
- analysis-type : type of analysis (harmonic or inharmonic).
- analysis-params : parameters for tracking
- for inharmonic partial tracking :
- Relative frequency derivation (mc) (default 20)
- Constant frequency derivation (Hz) (default 0.0)
- Relative amplitude derivation (%) (default 50)
- Source partial neighbors (default 1)
- target partial neighbors (>= source partial neighbors) (default 3)
- time gap to connect over (s) (default 0.017)
- frequency gap to connect over (mc) (default 50)
- minimum partial length (s) (default 0.009)
- for harmonic partial tracking : an SDIF f0 analysis file (automatically generated if nil)
- windowsize : the number of samples of the analysis window
- fftsize : the number of points of fft
- step : the number of samples between two successive analysis windows
- windowtype : the shape of the analysis window
- smoothing-enveloppe : smoothing enveloppe attack and release times (s) (default '(0.0 0.0))
