How to add audio tracks to a project

There are two ways to add new audio tracks to a project.
* In the main menu, the Project > Load Sound... option opens a panel to choose the audio file to import.
* In the left side of the audio section, a click on the symbol below, to the right of the Master Track name, opens a popup menu and allows you to Load a Sound Track... .

If you have already loaded tracks, a history of the previously loaded files will appears in this popup menu under the Load a Sound Track ... option.

Now it is possible to load several tracks on a project, let's talk about the Master Track functionality. The aim of the Master Track is to merge all the audio tracks, and see preview of what the final sound will look like. We can say that the Master Track is to the project preview, what the Tracks are to the layers.
