A labelcopy must be supplied, mentioning format (7″, 10″ or 12″) track titles and tracks per side. Please also mention the prefered RPM in which the audio should be cut, or specify if the engineer can decide depending on the total time and the Frequency-spectrum of the supplied audio.

Extra cutting instructions always need to be mentioned on the labelcopy.

To get the most out of your audio and the cut, please take the optimum and maximum timings in consideration.

Size RPM Optimum.Timing Max.Timing site
7″ 45 4:00 5:00 – 7:00
7″ 33 5:00 6:00 – 8:00
10″ 45 7:00 9:00 – 12:00

Exceeding these times and RPM can effect the quality of the audio. The longer the timings, the more consequences it will have for the sound quality (spectrum) and sound level. Please consider the spectrum for vinyl mastering.
