Description:
Calculates the FFT of a Sound file using SuperVP.
The results of analysis are stored in an SDIF file which pathname is returned.
- <infile> : pathname or SOUND object to be analysed
- <begin-time> : begin time of the analysis
- <end-time> : end time of the analysis
- <windowsize> : number of samples of the analysis window
- <fftsize> : number of points in fft
- <step> : number of samples between two successive analysis windows
- <windowtype> : shape of the analysis window
- <gabarit> : output fft format
0 = logarithmic amplitudes
1 = amplitude
2 = phase
3 = phase, amplitude
4 = frequency, amplitude
5 = real, imaginary
Note that only sdiffiles at gabarit 3 and 5 can be used to recalculate a sound file using IFFT.
- <out> : output file pathname
