// Notes about sceAtrac buffer management
//
// sceAtrac decodes from a buffer the game fills, where this buffer has a status, 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)
//
// When streaming (modes 3-6), a game will call sceAtracGetStreamDataInfo to figure out what data
// to read and where to place it, and after doing that it'll call sceAtracAddStreamData with the amount
// of data it actually read. This will move the various pointers forward.
// Similarly, for a game to seek, it'll call sceAtracGetBufferInfoForResetting with a sample offset,
// and read that data into the buffer.
//
// 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.)
//
// TODO: What games use this?
//
// Most files will be in RIFF format.  It's also possible to load in an OMA/AA3 format file, but
// ultimately this works the same, just the loading process is a little different.
//
// 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. Also, our Atrac2 context implementation works like this.

// TODO: We should add checks that the utility module is loaded.
