FAQ Stereo Mastering

Mastering (also audio mastering) is the (artistic) final processing of sound recordings and the last step of music production before the creation of the recorded sound carrier.

In the mastering process, the mastering engineer usually receives a mix of the track as a stereo file, which he imports into his DAW (digital audio workstation). Here he first gets an overview of the sound, as well as the technical and musical state of the song.
