Extract ID3 / audio metadata
Read the descriptive tags (title, artist, album, cover art, ...) mediabunny finds in an audio or video container. ID3v2/v1, MP4 atoms, Vorbis comments and more, whichever the file has.
Runs on your device. The file is never uploaded.
Extract ID3 / audio metadata prints the descriptive tags mediabunny finds in a container, one name and value per line, with dates in ISO form. Embedded pictures are summarised by count, kind, MIME type and byte length rather than written out as files. Duration, bitrate and codec are not reported, and nothing here writes to the file you dropped.
Questions
What tags does it read?
Whichever descriptive tags mediabunny finds in the container, so ID3v2 and ID3v1 in MP3, atom metadata in MP4, Vorbis comments in Ogg and FLAC, and the equivalents elsewhere. Every field that has a value is listed as a name and value pair, with dates printed in ISO form. You get the tags the file carries, not a fixed list of fields with blanks.
Does it show cover art?
It reports the images without giving you the files. Embedded pictures are summarised on one line: how many there are, and for each one its kind, its MIME type and its size in bytes. The image data itself is not written out as a downloadable file, so if you need the artwork you will have to carve it from the container.
Does it report duration, bitrate or codec?
No. This reads the metadata tags only. Technical properties of the streams are a different question, and this tool does not answer it. What the tags do give you is often what a case turns on: a title, an artist, an encoder name, a creation or tagging date.
Why did the metadata read fail?
Because the container did not open. The message includes the underlying reason in brackets and notes that this reads MP3, MP4, WebM, Ogg, WAV and FLAC containers. Common causes are a truncated file, a renamed file that is not audio, and a raw stream with no container. Check what the file is with Detect file type.
What does "no metadata tags found" mean?
That the container parsed but carried no tag fields and no embedded images. Plenty of files are like this: transcodes, recordings straight off a device, and anything that has been through a scrubber. It is not evidence the file was cleaned, though a file that should have tags for its origin and does not is worth noting.
Can I remove these tags?
Not with this tool, which only reads and never writes a file. Metadata scrubber is the one that strips metadata. If the file is evidence, keep the original untouched and work on a copy, since removing tags rewrites the container and therefore changes every hash you have recorded for it.
