Audio metadata
Shows tags inside MP3, FLAC, OGG and Opus (artist, album, year, comments) — and strips them without re-encoding.
Parses audio metadata and shows what is stored. For MP3 — ID3v2 (TIT2 / TPE1 / TALB / TCON / TYER / COMM / USLT / APIC frames: title, artist, album, genre, year, comments, lyrics, cover art) plus legacy ID3v1 in the last 128 bytes. For FLAC — the VORBIS_COMMENT block (key=value list — typically artist / album / title / date / genre, plus the codec vendor string). For OGG Vorbis and Opus — the Vorbis comment packet that follows the identification packet. Stripping is byte-surgery without re-encoding: for MP3 the prefix ID3v2 header and suffix ID3v1 trailer are cut off; for FLAC the VORBIS_COMMENT block is replaced with an empty one (header + zero comments); for OGG the page containing the comment packet is overwritten with a minimal empty version and its CRC-32 (polynomial 0x04c11db7, per Ogg spec) is recomputed. The audio data is untouched, the file plays back the same. Useful before publishing a track from your local library, sending an mp3 from iPhone (Voice Memos leave GPS in comments), forwarding a podcast cut, or sharing a ringtone. Processing happens in the browser, the file never leaves your device.
