Mixing Tracks in Sound Composer

This procedure shows how to mix tracks in a Sound Composer Project.

Mixing tracks in the Sound Composer module allows you to control the gain of each track in the entire sound project, which can be useful in various application. For instance, you can interactively evaluate the perception effect of each source by listening while changing the gains.

Creating a dataset of sounds with different gains for the same source to be used later in a Jury Listening Test project is also seamless with the Mix table for Sound Composer.

To Mix Tracks in Sound Composer:

Prerequisites: You need a Sound Composer project including several tracks.
  1. Click located in the upper right corner of the Sound Composer Window to open the Mix table for Sound Composer.

    • save the Sound Composer project to save those changes in the *.scn file,
    • save a track to save the gain adjusted from the Mix table in the *.trk file.
  4. Click to name the sound resulting from the mix with the current settings (gain and mute state) and to display its waveform in a new window.
  5. Click to save the sound resulting from the mix with the current settings (gain and mute state) as a mono *.wav file.
