About this tool
Audio Metadata Viewer is a free online tool. View duration, bitrate, codec and channel info of an audio file.
After uploading an audio file, the tool parses the metadata tag at the head of the file and displays all available information: title, artist, album, year, genre, track number, lyrics, cover picture, etc. Supports ID3v1/ID3v2 for MP3, iTunes tags for MP4, and Vorbis Comment for FLAC/OGG.
Metadata is stored in specific data blocks of audio files. ID3v1 is fixed to 128 bytes at the end of the file, and ID3v2 is of variable length at the beginning of the file. The tool reads these data blocks, parses the field encoding (ASCII, UTF-8, UTF-16), and extracts text and binary data (such as cover pictures).
It is suitable for checking whether the labels of music files are complete, correcting erroneous metadata, or extracting cover pictures. Some music players display information from these tags. The tool only reads and does not modify, ensuring file security.
