Audio : Duplicating an audio channel
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.
