Audio Editor Window
The Audio Editor window displays audio files graphically. It allows you to view, play back, and edit individual audio files.
The Audio Editor displays your audio in two views:
The Overview (1) serves to navigate in the project.
The Main View (2) is the area where you can edit your audio files.
You can select different display modes for the two views. For example, one of them can show the waveform, while the other one displays the spectrogram.
Clicking Sync with Other View at the bottom synchronizes the two Audio Editor views, so that they display the same part of the audio file.
