Description:
Tracks sinusoidal chords 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)
- markers : markers for analysis (text file). If nil, markers of filename are used.
- max-partials : the maximum number of simultaneous partials
- amp-treshold : Amplitude treshold of analysis (-120 -> 0 dB)
- analysis-type : type of analysis ('averaged-spectrum or 'inharmonic-partial-averaging).
for inharmonic partial averaging, connect partial connection parameters if needed :
- Relative frequency derivation (mc)
- Constant frequency derivation (Hz)
- Relative amplitude derivation (%)
- Source partial neighbors
- target partial neighbors (>= source partial neighbors)
- time gap to connect over (s)
- frequency gap to connect over (mc)
- minimum partial length (s)
- 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
