Mix & Master FAQ
What do I need mastering for?
Mastering is important to give your song the necessary loudness and balance. During mastering, I always do my best to bring out that certain something extra from your track.
What do I do if I still don't like the mix/master after all the revisions?
Of course, I always try my best to fulfill your wishes regarding mixing/mastering. However, please remember that my personal perception always plays a role in the process. It's best to listen to my references before purchasing to better assess if you like my mixing/mastering style :)
5 extra revisions cost 29.95€.
What do I need to consider when recording/exporting my tracks?
It's best to sort all tracks in the project by their function, e.g. Hook Mains, Part Mains, Doubles, Adlibs, etc., and name them accordingly so that I know what's what. This makes my job much easier and also ensures that I understand your vision! Also, you shouldn't record your tracks too loudly so that they don't clip.
