Note that in WaveLab Elements 8, “mixing” would be done in the Audio Montage, which is limited in comparison to the “full” WaveLab 8. WaveLab is not really a multi-track environment, so make sure you can do what you intend before you purchase. WaveLab Elements 8 can have a maximum of 3 tracks (stereo or mono), whereas WaveLab 8 is unlimited.
