MP3 Tag Editor

The MP3 Tag Editor enables accurate management of ID3 metadata for audio files. It reads ID3v2.3 and ID3v2.4 frames, validates inputs, and writes tag data without re-encoding the audio stream. Core capabilities include setting title (TIT2), artist (TPE1), album (TALB), year (TDRC/TYER), and genre (TCON), as well as track number (TRCK), comments (COMM), composer (TCOM), and album artist (TPE2). Optional features cover embedded cover artwork (APIC), unsynchronized lyrics (USLT), and language/key encoding selection to ensure Unicode compatibility. A batch-edit mode supports queuing multiple files with per-file validation and a consolidated export. The tool returns a change summary and generates a new MP3 alongside the original, or replaces the file if requested, preserving all non-tag data. It enforces length constraints, validates year formats, and checks artwork size/format to avoid tag corruption. The design targets professionals and enthusiasts who require reliable library tagging without altering audio content. Use cases include preparing a music catalog for streaming, organizing a podcast archive, or standardizing metadata across a label’s library.
