The mixing process is a crucial step for the production of a hit song. While not sitting alongside our engineers, you will have the opportunity to add any information you think is necessary to achieve the desired result. References to other popular songs will be very useful to accommodate your needs. The online mastering process is not included.

We at MastAndMix have the equipment and the know-how to make your mix a great track. As well as in the mixing process, we give you the opportunity to send us all the informations useful to get the desired end result, as if you were sitting next to us.

Online Stem Mastering

Online Stem Mastering Service

Stem mastering allows you to work in different ways on groups of separate tracks (vocals, kick, snare, bass, other drums, other instruments). The stem mastering allows you to work more accurately on individual instruments (or groups of instruments) without changing the whole track in its entirety (e.g. compress the snare, but not the guitar or voice).
