Editing Audio

To edit audio, do the following:

  2. Browse to an audio file, select it and click the "Open" button

Audacity displays a visual representation of the audio (known as a waveform) and has controls for zooming in and out of this representation allowing you to focus on particular portions of your audio track. Hold down your mouse button and drag across the waveform to select a portion of the audio. This selection can then be deleted or copied and pasted whereever else you put your cursor in the wave form. See screencast below for demonstration of basic editing techniques.
