The MusicBrainz Server field specifies what MusicBrainz server to use, currently there is only one but it is expected there will be mirror servers available in the future.

The Do not match online if already have a MusicBrainz Unique id option allows you to skip over tracks that have already had a Unique id. This is very useful if you reload records that you have already analysed, so you do not re-analyse them which could take some time if you are loading many records, it also allows you to skip over records you have just analysed if the online MusicBrainz match has timed out and you need to rerun it. This option is not enabled by default because you may want to re-analyse records because of improvements in your Metadata, which may give a more accurate match.

When Jaikoz finds potential matches for a track it doesn't have all the album information required to calculate exactly the rating a match should be given unless the album is in the Jaikoz album cache. For example it will have the album name but the not list of countries the album has been released in. To get this information it has to do another query for each album and this would slow down matching because MusicBrainz only allows one query per second so by default Jaikoz only retrieves the full album information for the track with the best rating although Jaikoz caches album information so it doesnt have to lookup the same album more than once in a Jaikoz session Enabling the Retrieve extended release details for more accurate ratings option will retrieve the extra album information for all potential matches, this will make matching slower but more accurate.

If Prefer releases that have been used by other tracks is enabled, releases that have been used by other tracks will have their rating increased by the Release has been used by other tracks score in the Match Score preference. Enabling this option helps minimize the number of albums tracks are spread over.

Musicbrainz categorizes all releases into either Official, Promo, Bootleg or Pseufo Release - most releases are Official. IfPrefer offical releases is enabled, Official releases will have their rating increased by Release is an Official Release score in the Match Score preference. Enabling this option helps prevents incorrect matching to live bootleg tracks.

If Prefer releases of the following types is enabled all the release types checked below it will cause tracks with releases of one of the checked types to have their rating increased by the Release is one of the preferred release types score in the Match Score preference. This option can be used to favour original abums, singles or compilations.

The selected Preferred Country of release will give tracks with releases in this country a rating increase by the Release released in preferred country score in the Match Score preference.

The Track Duration must be within this number of seconds options lets you specify that the duration of any matching tracks must be within x seconds of the actual duration for this track. Matches can be upto x seconds shorter or longer to account for slight differences in encoding or possibly song versions.

If the Possible matches must be within track duration option is enabled then no track will be returned based on a metamatch unless its track duration is within the range specified, if it is disabled then these track will still be returned as long as their total metamatch score is high enough. This option does not effect tracks matched based on their PUID.

Jaikoz find the best few ten possible matches for a track then calculates a rating out of 100 for each track, and the highest rating track is selected by the Autocorrecter if its rating is above the minimum rating accepted. You can decide how the rating is calculated by adjusting how the rating is allocated. Some ratings are not used if the associated checkbox is not enabled in the Match Preferences, for example the Release is an Offical release rating is only used if you have enabled the Prefer official releases in the Match Preferences.

The Do not match if unable to Acoustic Id Match option will only match tracks that have an acoustic id. This increases accuracy but reduces the number of matches.

The Minimum rating required if meta match only option allows you to balance the number of matches against accuracy. If your track has no acoustic id the match is done purely on the Metadata, the higher this setting the more likely it is that any match made will be correct, but less tracks will get matched at all. If your track has an acoustic id this setting is ignored because acoustic ids are so accurate it is very likely that if an acoustic match is made it will be for the correct track (even if it is not for the exact version), and forcing a check on Metadata as well would throw away accurate matches for tracks with poor or incorrect Metadata. The default value is 70.

If the Acoustic Id match must also have minimum meta rating option is enabled then matching tracks matched by their acoustic id must also have a Metadata match higher then the value in Minimum rating required if have an Acoustic Id Match. This option is not enabled by default.

If the Prefer to use acoustic id if exists even if rating is less than metamatch option is enabled Jaikoz will always use match based on MusicIp Id over a metamatch regardless of which has the best score. Using a MusicIP id is safer than a metamatch for identifying the correct title because it does not rely on your file having correct Metadata. But when a track appears on multiple releases metamatches can be better at ensuring all tracks from one release are all tagged against the same release.

This lists most of the values that can possibly be populated by MusicBrainz upon a successful match, this includes text fields and Artwork. By default all fields are populated on a MusicBrainz match if MusicBrainz has a value, but you can select to only populate the field if it is empty , or never to populate it.

When matching cover art Jaikoz will attempt to finest the highest quality image it can from a variety of sources, the image is added to the audio file automatically but will like all tasks the image will not be saved until you save changes.

A release may have multiple release events, these consist of a Country and a Release Date. The When selecting year and country of release prefer to use option lets you specify what is more important - the country or the date of release.

The Translate foreign artist names to english where possible uses the english version of latin names where possible. this is useful if youre system is Englisg/latin based but you are have some tracks by non lation artists such as Chinese or Japanese which would be difficult to use otherwise.

If you successfully create an Acoustic Id (MusicIP PUID) for a track and you have successfully found a match on MusicBrainz, and your track has a Music Brainz Unique File Id, you can submit the pairing to MusicBrainz the database. You should only submit a pairing if you have confirmed that the pairing has been correctly and identified and you should not submit the same pairing more than once.

Musicbrainz has a Folksonomy cloud that can be used to tag artists, releases and tracks with anything you like. Jaikoz uses this to add genres at releases and track level. Because genres are subjective this feature is going to become more useful as more people submit their genres, so please give it a go. Jaikoz also uses the folksonomy cloud to fix the genre field when correcting songs from Musicbrainz.

Musicbrainz can store a list of the release you own and inform you of new releases by your favourite artists. Submitting releases can be done via the website but Submit Musicbrainz Collection provides an easier way to submit all the releases loaded in Jaikoz in one go.
