Duplicating an audio channel
Audio files sometimes separate the vocal sound from the background
audio and put them in different channels. Duplicating an audio channel
allows you to mute the other channel.
To duplicate an audio channel, click the Sound Mixer button in the
toolbar. Click the Attribute tab and select Duplicate audio channel.
Choose which audio channel to duplicate this may be Left or Right.
In recording voice-overs using the microphone, it will be recorded
on one channel only. You can improve the audio volume by using
this feature to duplicate across channels.
