public final class ID3v1Filter

extends BinaryFilter

implements RandomAccessFileSource

Extract metadata from an ID3v1 tag

It's a 128-byte block at the end of a file.

May appear on MP3, Ogg, Flac, and other files.

Note that it is unsupported with streams, at least for now. This is because of the overhead required in scanning to the end of the file.

                    java.text.ParseException

Note that the caller must already have called this.getByteStream() to obtain the raw data for the tag.

This module creates the document from the parsed ID3V1 metadata.
