Select the track that you would like to mute by clicking on the waveform. The waveform consists of the visual representation of the audio files' frequencies. It looks similar to a wave, with peaks and valleys. Split tracks contain two audio files that typically correspond to left and right tracks. In some multichannel audio files, up to seven tracks occur.
Depress the "Mute" button, icon or radio using your left mouse button in the "Track Control Panel." On a Macintosh system, the main mouse button works for this process. This panel appears to the left of each audio track. It typically contains information about the bitrate and frequency of the audio recording.
Play the track to confirm that the split track has been muted.
