Classes
struct	SampleEdit
	A state structure for a GUI sample editor. More...
struct	Song
	Represents a complete song, which is a collection of SongParts. More...
struct	SongPart
	Represents one of the 8 channels (tracks) in a song. More...
struct	SongRange
	A metadata structure to keep track of parsed sections of the song data. Used to avoid re-parsing the same data from the ROM multiple times. More...
struct	SongSpcBlock
	Represents a block of binary data destined for the APU (SPC700) RAM. This is the intermediate format used before writing data back to the ROM. More...
struct	SpcCommand
	The core data structure representing a single command in a music track. A song track is a doubly-linked list of these commands. More...
class	Tracker
struct	ZeldaInstrument
	Defines an instrument for a song, mapping to a sample and ADSR settings. More...
struct	ZeldaSfxInstrument
	Defines an instrument for a sound effect. More...
struct	ZeldaWave

Detailed Description

Contains classes and functions for handling music data in Zelda 3.

Based off of the Hyrule Magic tracker code, this system is designed to parse the game's complex, pointer-based music format into an editable in-memory representation and then serialize it back into a binary format that the SNES Audio Processing Unit (APU) can understand.
