| WIN | 'BH92' |
|
The spectral window to apply to the data. |
| NOLAP, OLAP | -1 | none | The segment overlap (%). |
| NFFT | -1 | none | The number of samples in each short fft. |
| FREQVEC | -1 | none | Vector of frequencies where to calculate the spectrogram according to the Goertzel Algorithm (optional). By default, FFT algorithm is applied; only if this parameter is set then the Goertzel Algorithm is used. |
| NORMALIZE | 0 |
|
Normalize the spectrogram by the median power spectral density. |
