Since 1991


We provide 2 different online mastering services: Stereo and Stem. Stereo Mastering is the more traditional, where a simple stereo audio file goes through the process of correction, equalisation, enhancement and compression. Stem Mastering is for when multiple sub-mixes are available (individual mixes for drums, bass, guitars, synths, vocals etc.) and it allows for even greater results, giving the mastering engineer additional control over the main balance of the mix.


Everything that a professional mastering engineer would normally do. It just so happens I am actually a PROFESSIONAL mastering engineer so I know how to do stuff.
