Multichannel audio workflow

Multichannel Audio Workflow

You can use Adobe Audition to easily work with multichannel audio up to 32 channels. In the Waveform Editor, you can individually edit and process specific audio channels. You can also work with multichannel files in the Multitrack Editor as a single clip or with the channels split across multiple clips.

Waveform Editor

If you have multichannel audio or video files, you can edit each audio channel separately in the Waveform Editor by following these steps.

  1. Select File > Open. The opened file appears in the Files Panel.

  2. Expand the drop-down to see each of the channels within the file.

Multitrack Editor

To use multichannel audio or video files within a session, you can bring each of the channels of the file into the Multitrack Editor as one single multichannel clip (default behavior). You can also automatically split each channel or groups of channels into different clips by holding Alt (Windows) or Option (Mac) while dragging.
