This PDF contains all the things you need to know before mastering.

File Format

Stereo WAV or AIFF is preferred.


24 bit or 32 bit float.

Sample Rate

44.1 kHz or higher. Do not sample rate convert the mix yourself.


The mix should peak below 0 dBFS.

Plug-ins On the Master Bus

If you are using plug-ins on the master bus then please make one version with, and one without, plug-ins. Limiting or clipping the master bus should always be avoided.


Do not fade out the file yourself but tell me where the fade should begin and end.


Make sure you include the whole of the start and the end of the song when exporting.

Alternative Versions

Extended, edit, singback, etc. must all be otherwise identical to the main version.

Red Book Master CD or DDP Image

A downloadable DDP image is the preferred format used for CD replication. A DDP can contain ISRC and other codes. A Red Book Master CD is a physical alternative to a DDP.

ISRC - International Standard Recording Code

If your music is to be sold on iTunes, you need ISRCs. If your music is being played on the radio, ISRC is an advantage for identification purposes.

You get the first part of the ISRC from your local department of IFPI. The full code consists of the items below, and each song will be assigned a unique ISRC:

QZ-ABC-18-001-01 (country-record label-year of registration-release-track)

Gracenote CD Database

For iTunes and similar software to show the correct title and track names automatically, you need to submit your CD to Gracenote. Read more about how to submit your CD to the Gracenote Database.
