Hi there Antonio
I think you're maybe confusing 'bouncing to stereo' with 'mixdown'/'export audio'.
'Bouncing' tracks is, generally speaking, a throwback to the earliest multi-track (tape) recording decks. It was used to 'combine' two or more tracks to free up space for further recording. For example, if you were working with a four-track recorder and used three of the tracks to record bass, guitar and drums, you could, once you were happy with the mix, bounce the three tracks to the free track (or even to another recorder). In this example, your rhythm section would now only occupy one track, leaving the other three free to overdub vocals and solos etc.
The 'Mixdown' of a
completed project may well have been the final bounce to create a single stereo track ready for mastering or copying to an LP master.
Incidentally, you can perform both of these actions in SONAR.
However, if you are trying to end up with a mixed-down .wav file of your project
outside of SONAR, you can use any of the various the 'Export' options. Once you're happy with the mix of your project, select
File > Export Audio and select the options you require for the new audio file you will create. For example, if you wanted the resultant audio file to eventually be burned to CD, you might select a
Stereo Wave of the
Entire Mix at
44,100Hz/
16bit (the current standard for CD audio).
The beauty of exporting your mix in this way is that it isn't a 'destructive' process - in other words, none of your original project is altered in any way. This means you can go back and edit your project at any time, and even export the same project as different file types.
