A MusicBrainz Recording is defined as a unique mix, where a mix is the result of editing and mixing one or more stems.
A stem is one or more raw audio tracks, typically captured from a studio performance, but possibly created from other audio sources. See the Wikipedia article for more information.
For the purposes of MusicBrainz, mixing is defined as changing the volume of a particular stem relative to other stems. It also covers things such as volume fading, or muting a track completely.
Editing of stems generally takes place before mixing, and is more to do with changing the positioning and duration of each stem. Moving a drum solo from the end of one chorus to the end of the next is an example of editing. Shifting background vocals along a few seconds so that they start at a different point in the song is another example.
It should be noted that mixing and editing usually apply to stems rather than the whole song. These two processes take place before the completion of the song. Mastering is a related process that is applied to the whole song after completion, to prepare it for a particular release.
These are all different Recordings:
Please see the guidelines for recordings.
The title of the recording.
The artist(s) that the recording is primarily credited to.
An approximation to the length of the actual mix, calculated from the lengths of the tracks using the recording.
The International Standard Recording Code assigned to the recording.
