// Notes about sceAtrac buffer management
//
// sceAtrac decodes from a buffer the game fills, where this buffer is one of:
// * Not yet initialized (state NO DATA = 1)
// * The entire size of the audio data, and filled with audio data (state ALL DATA LOADED = 2)
// * The entire size, but only partially filled so far (state HALFWAY BUFFER = 3)
// * Smaller than the audio, sliding without any loop (state STREAMED WITHOUT LOOP = 4)
// * Smaller than the audio, sliding with a loop at the end (state STREAMED WITH LOOP AT END = 5)
// * Smaller with a second buffer to help with a loop in the middle (state STREAMED WITH SECOND BUF = 6)
// * Not managed, decoding using "low level" manual looping etc. (LOW LEVEL = 8)
// * Not managed, reserved externally - possibly by sceSas - through low level (RESERVED = 16)
