Types

type Parser

type Parser struct{}

Parser parses ID3v2 and ID3v1 metadata from MP3 files.

Supported formats:

• ID3v2.4 (preferred, released 2000)
• ID3v2.3 (common, released 1999)
• ID3v2.2 (legacy, released 1998)
• ID3v1 (fallback, at end of file, released 1996)

The parser uses io.ReaderAt for efficient random access without loading the entire file into memory.

func (*Parser) Parse

func (p *Parser) Parse(r io.ReaderAt) ([]parser.Directory, *parser.ParseError)
