Mastering and post-production
The term “Mastering” comes from the period where analogue multitrack tape recordings where transferred onto vinyl records. During the Mastering , end mixes or any other existing mix, can still be enhanced. We strongly advise to do this if it is the intention to bring the recording on a CD together with others. Practically inaudible peeks can thus be removed from the signal, without important interference with the dynamics of the song, which thus sounds louder. If this is not done the track will sound a lot softer on the final CD. (this may be considerable ). Predominantly to this it will be played less by radio stations, because their equipment is tuned for a fixed volume.
Possible treatments are, for example: compression, limiting, EQ-ing, the cleaning of quiet passages and breaks, time-stretching in commercials in order to influence the length without changing the tone, mixing of numbers, editing of transitions, editing of intros and outros, fades (in, out, crossfades), the polishing out of disturbances and cracks in the signal, noise suppression, the order of the numbers and, of course, PQ – ISRC coding.
