Jaikoz is a computer program used for editing and mass tagging music file tags. Jaikoz was the first tagger available that could perform acoustic fingerprint matching automatically without user intervention--the majority of taggers only provide a metadata lookup and, because of the inaccuracy of this method, requires the user to confirm modifications. Accuracy is determined by the completeness of the database being used and the quality of the recording. Jaikoz uses the MusicBrainz service. It generates fingerprints (TRM Recognizes Music-hashes) of your files and compares them with the data from the MusicBrainz server.

Jaikoz also provides a novel-matching algorithm that compares the metadata files to each other, and performs an analysis on the sameness of values. If sufficiently similar, the values are changed to the most popular value. This mechanism allows automatic correction of typos. For example, if there were fifty records with the artist name "The Beatles" and ten with the artist name "The Beetles," the sameness of the two values would indicate they were the same and all values would be modified to the most popular (the correct) value "The Beatles."

Jaikoz provides a unique user interface--a split-datasheet view of the metadata, allowing data to be compared before and after editing and quick editing of all metadata, not only the most common metadata fields.

Jaikoz is developed in Java and, hence, is available for most operating systems.
