AudioExplorer's Spectrum Window

 

In batch mode, AudioExplorer can prepare spectra at configurable time-slices spanning the entire audio file. 

The Spectrum Form allows you to view these spectra in series, providing statistical and visually representations of the frequency distribution at each time slice.

 

Toggle between logarithmic and linear displays, and lock/unlock axes. View the sample content and distribution of any spectrum.
View data as frequencies (Hz) and as notes.
Select and view spectra corresponding to any time in the audio file.
