Part 1: What is Submix

An audio submix is an intermediate output track where you can group a set of related or connected audio clips or tracks so that the same effects or treatments can be applied to them simultaneously.

You could send recorded clips from the same musical instrument to one submix so they can be edited as a group. You could also send a group of related signals such as the components of a dialogue or background sound like footsteps, background music, the sound of moving cars, etc, to one submix so they can be processed for a more natural background sound in a video.

Once you are satisfied with the effects you've applied to your submixes, you can them route them to the master track to generate the final audio output. Most advanced multimedia editors like Premiere Pro make it easy to create a submix but will not allow for tracks to be recorded directly to a submix. That's because a submix is a feature for audio editing and mixing.

Premiere Pro also allows users choose how much of the signal of an audio track will be sent to a submix and in this way, lets users choose which sounds will be highlighted in the final audio track.

• Right click or control click the TRACK HEADER and in the context menu, select ADD AUDIO SUBMIX TRACK.

Once your submix has been created, it will appear as a new track to the right of your existing tracks panels and just before the master track in the AUDIO TRACK MIXER window.

• The first thing to do after creating the submix is to route/send the desired audio tracks to it. To do this, go to the panel for each track in the AUDIO TRACK MIXER and in the TRACK OUTPUT/SEND ASSIGNMENT menu which is set to MASTER by default, click the down arrow and select the SUBMIX as the output. Note that the submix itself is set to output to the MASTER TRACK.
• With all desired tracks sent to the submix, applying an effect to the submix will apply the effect to all the tracks routed or sent to the submix.
• Be sure to adjust the signal output dial for each track to choose how much of a track’s signal to send to the submix. This will let you achieve more nuanced effects and a more natural sound to your audio track.
