Types

type Tag

type Tag struct {
	Title  [30]byte
	Artist [30]byte
	Album  [30]byte
	Year   [4]byte
	// The track number is stored in the last two bytes of the comment field.
	// If the comment is 29 or 30 characters long, no track number can be stored.
	Comment  [30]byte
	ZeroByte byte
	Track    byte
	Genre    byte
}

type TagPlugs

type TagPlugs struct {
	Title  [60]byte
	Artist [60]byte
	Album  [60]byte
	// 0=unset, 1=slow, 2= medium, 3=fast, 4=hardcore
	Speed uint8
	// A free-text field for the genre
