The fifth bit in c- should be used as an “experimental flag”.Īll other flags must be cleared. ID3v2 flags The sixth bit in b- indicates header if there are extended header followers. ID3v2 flags The seventh bit in a- indicates whether unsynchronization is used. ID3v2 version Followed by one ID3v2 flags, currently only 3 flags are used:

If software compatible with ID3v2.2.0 and lower encounters version 3 or higher, it should simply ignore the entire tag. All revisions are backward compatible, while major versions are not. The first byte is your major version, while the second byte is your revision number. The first three bytes are always ID3, indicating that it is an ID3v2 tag, followed by two version bytes. The bit order in ID3v2 is Most Significant Bit First (MSB).īyte order in multibyte numbers is most significant byte first (for example, 0x12345678 would be encoded as 0x12 34 56 78), also known as big-endian storage. TagInclude tag header, tag body(1 or n frame), optional padding. Tages the complete tag described in this document. The label has the following layout (shown in the schematic on the right): To facilitate detection, a fixed size of 128 bytes was chosen. The location of the tag, as the data calls it, may be because it has little chance of interfering with the decoder. By adding a small piece of extra data to the end of the file, you can make MP3 files contain information about the audio, not just the audio itself. A solution to this problem was presented in 1996 by Eric Kemp. original” (meaning this is the original document and not a copy). The MPEG Layer I, Layer II, and Layer III (MP3) audio format does not have a native way of preserving content information, except for some simple yes/no parameters like “private”, “copyrighted” and “family”.
