User Guide/Workspace/Application and Setup Tree/Signal Analysis and Display/Profile

A profile is a specific graphical and analysis parameter setup for a particular viewer. They are stored in the Workspace file and can be edited in the Application & Setup Tree. Each viewer application comes with a number of pre-configured profiles. Profiles can be copied, renamed and deleted. In order to create a new profile, copy an existing profile and then make the necessary changes to it's name and settings.

Pre-configured Profiles

STx comes with a number of pre-configured profiles.

Waveform & Segmentation Viewer

Default

The default profile, with one line.

3_Rows

This profile displays the selected signal (segment or sound file) in three rows.

Spectrogram & Parameters Viewer

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

Spectrum_Bands_2CB Wavelet_Amplitude Wavelet_Phase
