A clear track-index must be supplied with the master.

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 respect below timings:

Size RPM Optimum.Timing Max.Timing
7″ 45 4:00 5:00 – 7:00
7″ 33 5:00 6:00 – 8:00
10″ 45 7:00 9:00 – 12:00
10″ 33 9:00 11:00 – 15:00
12″ DJ 33 10:00 12:00 – 15:00
12″ DJ 45 8:00 9:00 – 10:00
12″ LP 45 9:00 12:00 – 18:00
12″ LP 33 18:00 21:00 – 32:00

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.

Audio Upload
Record Industry is also able to process audio supplied per FTP. The audio upload system is completely secured and protected against piracy. However, there are a few guidelines one has to follow to be able to use the system.

You report your company once via Once your initial enquiry has been authorised Record Industry Spain will contact you via email, assigning a password and login-name. You now have acces to the upload system.


The following file types can be uploaded:
Audio files (44,1 KHz up to 96 KHz) (16 up to 24 bit)
Wave files (44,1 KHz up to 96 KHz) (16 up to 24 bit)
AIFF files (44,1 KHz up to 96 KHz) (16 up to 24 bit)


    • All files per upload need to be of the same format. When there are several formats in one file, extra re-sample charges will be calculated.
    • It is possible to supply losless data compressions (RAR, ZIPP and ARJ)
    • Audiodata compressions like MP3, WMA etcetera are not accepted


For a cut at 45 RPM we need a loop of 180 BPM and and at 33 RPM we need a loop on 133,33… BPM.
The length of the loop must be about 20 sec.
The customer need to tell if he like the endless loop at the end of the audio or at the end of the lead-out groove.
