// 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)
//
// This buffer is generally filled by sceAtracAddStreamData, and where to fill it is given by
// either sceAtracGetStreamDataInfo when continuing to move forwards in the stream of audio data,
// or sceAtracGetBufferInfoForResetting when seeking to a specific location in the audio stream.
//
// State 6 indicates a second buffer is needed. This buffer is used to manage looping correctly.
// To determine how to fill it, the game will call sceAtracGetSecondBufferInfo, then after filling
// the buffer it will call sceAtracSetSecondBuffer.
// The second buffer will just contain the data for the end of loop. The "first" buffer may manage
// only the looped portion, or some of the part after the loop (depending on second buf size.)
//
// Most files will be in RIFF format. It's also possible to load in an OMA/AA3 format file, but
// ultimately this will share the same buffer - it's just offset a bit more.
//
// Low level decoding doesn't use the buffer, and decodes only a single packet at a time.
//
// Lastly, sceSas has some integration with sceAtrac, which allows setting an Atrac id as
// a voice for an SAS core. In this mode, the game will directly modify some of the context,
// but will largely only interact using sceSas.
//
// Note that this buffer is THE view of the audio stream. On a PSP, the firmware does not manage
// any cache or separate version of the buffer - at most it manages decode state from earlier in
// the buffer.
