Step-by-step explanation:
The sum of all channels in a session is usually referred to as the Master Track. It combines all the audio channels or tracks in a recording or mixing session to create a final mix.
For example, in music production software like Ableton Live or Pro Tools, the master track is where all the individual instrument and vocal tracks are routed to create a stereo or surround sound mix. The master track allows you to add effects, adjust volume levels, apply equalization, and apply overall mastering to the final mix.
In video editing software, the master track is where all the video and audio tracks are combined to create the final video.
When working in a digital audio workstation (DAW), each instrument or voice is typically recorded on a separate track or channel. These channels are then mixed together to create the final audio output, which is referred to as the master track or stereo mix.
