About Extract Audio Metadata
Extract common audio metadata across MP3 (ID3v2/ID3v1/GEOB), WAV/BWF/BW64 (INFO/bext/iXML/axml), FLAC (Vorbis Comment/Picture), OGG (Vorbis/OpusTags), AAC (ADTS), AC3 (Dolby Digital), WMA (ASF), plus best-effort MP4/M4A and AIFF scanning. Outputs normalized JSON.
Input: binary bytes (text input uses UTF-8; a file retains its original bytes). Output: structured JSON.
Format reference: Extract Audio Metadata background and specification

Before interpreting the result
Extractors find patterns; a matching address or identifier is not proof that it exists or is reachable. Inspect the sample and matching options to understand false positives.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
