How to use Audio ranges for audio redaction
Open the Audio Tab next to the Timeline. Here you can see a waveform of the audio in your video/audio file.
There are two ways to create an Audio range (an audio range is a portion of audio that is selected for redaction).
Pause the video/audio file. Click Redact audio from the Audio Toolbar (bottom left in the Audio Tab). The video will begin to play. An orange bar (Audio range) will simultaneously be created on the audio waveform.
Click on the waveform and drag forwards to the point where you want to redact.
All Audio ranges are shown with exact timestamps in the Audio Ranges Panel on the right-hand side (to open, click Audio ranges, under Transcript, right).
Click, hold and move any orange bar on the waveform to adjust its position. You can also click and drag the Audio range ends to make them longer or shorter.
Also in the Audio Toolbar
Review redacted audio (Headphones button, bottom left) - used to preview your audio redaction. It will invert the audio, so that whilst you watch the video/listen to the audio file, you will only hear the selected Audio ranges and the rest of the video will be mute. This is extremely useful for ensuring that all parts of the audio that you need are fully selected for redaction.
Keyboard shortcut: A
Arrows - to go to skip to the start/end of Audio ranges.
Redact audio - to start/stop an Audio range.
Keyboard shortcut: G
Delete - to delete an Audio range (this cannot be undone).
Keyboard shortcut: backspace
Audio only mode - this temporarily dismisses the visual part of the video, and brings up the Transcript, so that you can focus solely on Audio redaction. Click Video mode to go back to editing both video/audio at the same time.
