Mastering means optimizing your final mix for a special usecase or musical style.
From 30 years of experience, mixing and testing my productions in the clubs and festivals, I know how authentic Techno- and Clubmusic has to sound like.
By request, I will get back to you with my impression concerning your mix and if I would recommend any changes to get a better result after mastering. This feedback is free of charge.
You deliver your final mix (premaster) as a Wave file (44,1/48KHZ and 16/24bit) and when the master is ready, I will send a password protected "wetransfer link" to you.
Once the payment is done, you will receive the password to download your master (also in MP3 if requested) ready to be played in the clubs or released on platforms like Beatport, Spotify etc .
You have 2 revisions included, in case you want any changes after.
