![]() ID3v2.3 – an improved version of ID3v2, uses 4 characters for frame identifiers (the original version used 3 characters) and has more predefined frames.ID3v2.2 – the first version of ID3v2, now obsolete.In general, there are 3 versions of ID3v2: Furthermore, new types of fields could be easily defined without changing the existing specification. There were more predefined fields, including fields for lyrics and album art. Now a field could contain up to 16 MB of data, so a big novel would easily fit. Length of fields (frames) in ID3v2 became variable. ![]() This made it suitable for streaming media. ID3v2 was appended at the beginning of an MP3 file. ID3v1 was added at the end of an MP3 file to ensure compatibility with older players. While the same name suggests a further improvement of ID3v1, the format is completely different. In 1998, several contributors created a new specification of ID3 tags, now known as ID3v2. This layout was quite rigid, so you could not save 20 characters of a title and use the remaining 10 characters for the artist field.Ī year later, in 1997, Michael Mutschler decided to take 2 bytes from the comment field and store the track number. The original ID3 tag version (ID3v1) included the following fields:ģ more characters were used for the header of the ID3 data block. This enhancement was later called ID3 tag and became a de facto standard for saving meta-information in MP3 files. This allowed saving 128 characters of text inside the audio file, which was way better than just 8 characters in filenames. A small (128 bytes) chunk of data was appended at the end of an existing MP3 file. In 1996, an enhancement was suggested by Eric Kemp. However, filenames in MS-DOS and early versions of Windows could have only 8 characters. One can think of saving some basic details (at least title and artist) as filenames. No textual information could be stored inside MP3 files themselves, which meant no artist, no title, no album, and so on. Although technically the MP3 format was quite perfect, there could be a difficulty identifying particular MP3 files. Soon after its release, a problem was discovered. It is part of the MPEG (Moving Picture Experts Group) standard. The MP3 format was made publicly available in 1993. All supported tag formats are processed in the same way, so you can easily rename or tag a mixed group of files. Later, support for other popular formats was added, and now the program also works with OGG, WMA, APE, FLAC, AAC, MPC, WV, M4A, MP4, WAV files. As its name suggests, mp3Tag Pro was initially created to handle MP3 tags.
