Pre-Configured Profiles

The Spectrogram & Parameters Viewer comes with the following pre-configured profiles.

Default

The default profile, using a spectrogram and waveform plot, and the Sectioner windows.

FFT_1Hz

This profile analyses the signal using a 1Hz band width FFT, displaying the spectrogram frequency scale in Hz.

FFT_1Hz_Bark

This profile analyses the signal using a 1Hz band width FFT, displaying the spectrogram frequency scale in Bark.

FFT_22Hz FFT_Speech_F0

This profile analyses the signal using a 90Hz band width FFT, and calculates the fundamental frequency using the f0 autocorrelation method.

FFT_Speech_FOR

This profile analyses the signal using a 90 Hz band width FFT, and calculates both the fundamental frequency using the autocorrelation method, as well as calculating the formants.

Spectrum_Band_Level

This profile analyses the signal using a 22 Hz band width FFT, and then calculates the RMS value in 10 bands between 0 and 8000 Hz.

Spectrum_Bands_2CB

This profile is the same as Spectrum_Band_Level, except that the bands are manually defined.

Wavelet_Amplitude

This profile displays a spectrogram calculated with a wavelet amplitude spectrum.

Wavelet_Phase

This profile displays a spectrogram calculated with a wavelet phase spectrum.
