AudioExplorer's Audio Window

 

The Audio Window is used for interactive analysis of an audio waveform and for playback/record.

It consists of three integrated sub-panels:

 

The waveform display is fully zoomable.  Spectral content of selections made in the waveform are shown  in the piano or frequency displays.
Frequency is displayed as piano notes or as a needle graph.  During audio record/playback, the audio spectral content is displayed real-time.
The Note Map panel is fully zoomable.  During audio playback, a cursor marks the current position in the music.
