A group of audio tracks used in a recording can be mixed and possibly edited in a different way. For example, the volume or tone of individual tracks may be altered, or effects may be applied to them. The result is often labelled on a track list as a remix, mix, dub or version, and should always be given a new recording in MusicBrainz.

|Status: This page describes an active style guideline proposal and is not official.|
JIRA ticket http://tickets.musicbrainz.org/browse/STYLE-208
This proposal implements the changes to recordings discussed in the three recordings meetings held during January 2013. The meetings were open to all of the MusicBrainz community, and issues were discussed thoroughly, so any criticism of this proposal should hopefully be focused on the wording, and not the principles.
This proposal replaces the current Recording Style Guideline with the new revision in the section below.
- 1 Name
- 2 Artist
- 3 Using Recordings
- 4 Merging Recordings
- 5 Specific types of recording
- 6 Examples
See the title guidelines for how to enter the recording's title.
The artist should usually be the same as the first release of the recording.
A recording is a set of one or more audio tracks, which may have been mixed or edited, but have not been mastered for a release. In many cases, a released track will feature the original recording produced from a performance. However, there are some important cases to consider where this is not true - these are discussed in the following section.
Different performances of the same work should always be given separate recordings, no matter how similar they may sound. This applies to both studio performances and live performances.
Audio recordings of the same performance from different sources will always have different audio. A new MusicBrainz Recording should be created for each track created from different audio recordings.
A group of audio tracks used in a recording can be mixed and possibly edited in a different way. For example, the volume or tone of individual tracks may be altered, or effects may be applied to them. The result is often labelled on a track list as a remix, mix, dub, overdub or version, and should always be given a new recording in MusicBrainz.
An existing recording can itself be edited to produce a new recording. For example, a "radio edit" or "single edit" may be produced by removing an intro or outro, verses, bridges or interludes to shorten the existing recording, and/or by censoring some of the content. Other examples include an edit using only a section of a recording or an "extended edit" which repeats parts of an existing recording to increase the duration.
Where a fade is added to the first or last section of an existing recording, this is not an edit, as the section is not removed.
Number of Audio Channels
It may be the case that very similar released tracks have different numbers of audio channels. The most common audio channel configuration is stereo (two channels; left and right). However, there are several common audio channel configurations used in recordings, including mono (one channel), quadraphonic (four channels) and surround sound (various multi-channel configurations).
These different configurations should generally be distinguished by using separate recordings. However, the original multi-channel recording should be used when multiple channels have been combined into a single channel without actually creating a new mix from the source audio tracks. A similar exception should be made where a mono channel has been split into two stereo channels - for example, in Duophonic recordings.
In addition to the above guidelines, it is extremely important to take the following into consideration when thinking of merging recordings.
Recordings with Different Durations
Recordings of different durations can be merged, as long as there is no evidence to suggest that differences in mixing or editing have caused the change in lengths.
Variations in the length of silence at either end of tracks is not a reason to keep recordings separate, since no changes have been made to the audio itself. Similarly, different volume fades at either end of multiple tracks are not reasons to maintain separate recordings - they are considered mastering differences unless they cause the structure of the song to change. The same is true for variations in playback speed between recordings.
Recordings with Different Mastering
As mentioned in Recording, in MusicBrainz, mastering is a process that is applied to recordings to prepare them for release in a particular format. This means that tracks should not use separate recordings because of mastering differences.
Following on from this, separate recordings should not be created for remastered tracks, since remastered tracks generally feature the original recording with different mastering applied. Remastering should be described using the Remaster Relationship Type between releases, or in the release annotation where tracks are mastered differently across a release. The exception to this is where a track labelled as a remaster is in fact a remix - in this case, follow the remix guidelines above.
Recordings with Conflicting Relationships
Generally, don't merge recordings if they have conflicting relationships. However, if you're certain that two recordings are the same and relationships are wrong, merge the recordings and correct the relationships.
Specific types of recording
For live recordings, enter the song name as the recording title and "live" as the recording disambiguation comment. If the date and/or location is known, this should also be added to the disambiguation comment following the same format as used on live bootlegs.
- Train in Vain (live, 1998-12-14: Telewest Arena, Newcastle, UK)
- Wake Up (live, Los Angeles, CA, USA)
- The Dance (live, 2002)
- Candle in the Wind (single edit) (live)
- When The Beatles' studio albums were originally released as CDs in 1987, they were remastered from the original mixes with the exception of Help! and Rubber Soul, which were remixed. A Day in the Life is used on both the 1967 and the 1987 stereo releases of Sgt. Pepper's Lonely Hearts Club Band, while the Yesterday from the original stereo release of Help! is a different recording to the Yesterday remix from the 1987 CD release.
- The original recording Don't Push appears on tracks which vary in length from 3:45 to 3:55 because they have been mastered at different speeds. Therefore, the pitch of the audio is different on these tracks, but because there is no difference in mixing they are considered the same recording. The album version, Don't Push, appears on many releases at different levels of loudness, with differences in dynamic range and with different tonal qualities. However, again there is no evidence that this was the result of mixing and therefore these different tracks are one recording.
- The tracks on the 1973 stereo edition of Pink Floyd's The Dark Side of the Moon all use different recordings to the 1973 quadrophonic edition of the same album, since each version was mixed independently for different numbers of audio channels.
- Four different studio recordings of the song Punky Reggae Party were released by Bob Marley & The Wailers. The B side of the 12" "Jamming" single and the B side of the 7" "Jamming" single are shortened edits of the A side of the 12" "Punky Reggae Party" single, reducing the length of the original from 9:18 to 6:52 and 4:25 respectively. The B side of the 12" "Punky Reggae Party" single is a different mix, with many of the vocals removed and other effects applied during the mix.
- Glenn Gould has performed and recorded at least two different interpretations of Bach's Goldberg Variations. As these are two different performances, there is a separate recording for each; the 1955 performance and the 1981 performance. Although these recordings have similar lengths and relationships, they should definitely not be merged.
