* Overview
***************************************************************************/
// A typical XMA2 file contains these RIFF chunks:
//
// 'fmt' or 'XMA2' chunk (or both): A description of the XMA data's structure
// and characteristics (length, channels, sample rate, loops, block size, etc).
//
// 'seek' chunk: A seek table to help navigate the XMA data.
//
// 'data' chunk: The encoded XMA2 data.
//
// The encoded XMA2 data is structured as a set of BLOCKS, which contain PACKETS,
// which contain FRAMES, which contain SUBFRAMES (roughly speaking). The frames
// in a file may also be divided into several subsets, called STREAMS.
//
// FRAME: A variable-sized segment of XMA data that decodes to exactly 512 mono
// or stereo PCM samples. This is the smallest unit of XMA data that can
// be decoded in isolation. Frames are an arbitrary number of bits in
// length, and need not be byte-aligned. See "XMA frame structure" below.
//
// SUBFRAME: A region of bits in an XMA frame that decodes to 128 mono or stereo
// samples. The XMA decoder cannot decode a subframe in isolation; it needs
// a whole frame to work with. However, it can begin emitting the frame's
// decoded samples at any one of the four subframe boundaries. Subframes
// can be addressed for seeking and looping purposes.
//
// PACKET: A 2Kb region containing a 32-bit header and some XMA frames. Frames
// can (and usually do) span packets. A packet's header includes the offset
// in bits of the first frame that begins within that packet. All of the
// frames that begin in a given packet belong to the same "stream" (see the
// Multichannel Audio section below).
//
// STREAM: A set of packets within an XMA file that all contain data for the
// same mono or stereo component of a PCM file with more than two channels.
// The packets comprising a given stream may be interleaved with each other
// more or less arbitrarily; see Multichannel Audio.
//
// BLOCK: An array of XMA packets; or, to break it down differently, a series of
// consecutive XMA frames, padded at the end with reserved data. A block
// must contain at least one 2Kb packet per stream, and it can hold up to
// 4095 packets (8190Kb), but its size is typically in the 32Kb-128Kb range.
// (The size chosen involves a trade-off between memory use and efficiency
// of reading from permanent storage.)
//
// XMA frames do not span blocks, so a block is guaranteed to begin with a
// set of complete frames, one per stream. Also, a block in a multi-stream
// XMA2 file always contains the same number of samples for each stream;
// see Multichannel Audio.
//
// The 'data' chunk in an XMA2 file is an array of XMA2WAVEFORMAT.BlockCount XMA
// blocks, all the same size (as specified in XMA2WAVEFORMAT.BlockSizeInBytes)
// except for the last one, which may be shorter.
// MULTICHANNEL AUDIO: the XMA decoder can only decode raw XMA data into either
// mono or stereo PCM data. In order to encode a 6-channel file (say), the file
// must be deinterleaved into 3 stereo streams that are encoded independently,
// producing 3 encoded XMA data streams. Then the packets in these 3 streams
// are interleaved to produce a single XMA2 file, and some information is added
// to the file so that the original 6-channel audio can be reconstructed at
// decode time. This works using the concept of an XMA stream (see above).
//
// The frames for all the streams in an XMA file are interleaved in an arbitrary
// order. To locate a frame that belongs to a given stream in a given XMA block,
// you must examine the first few packets in the block. Here (and only here) the
// packets are guaranteed to be presented in stream order, so that all frames
// beginning in packet 0 belong to stream 0 (the first stereo pair), etc.
//
// (This means that when decoding multi-stream XMA files, only entire XMA blocks
// should be submitted to the decoder; otherwise it cannot know which frames
// belong to which stream.)
//
// Once you have one frame that belongs to a given stream, you can find the next
// one by looking at the frame's 'NextFrameOffsetBits' value (which is stored in
// its first 15 bits; see XMAFRAME below). The GetXmaFrameBitPosition function
// uses this technique.
// SEEKING IN XMA2 FILES: Here is some pseudocode to find the byte position and
// subframe in an XMA2 file which will contain sample S when decoded.
//
// 1. Traverse the seek table to find the XMA2 block containing sample S. The
// seek table is an array of big-endian DWORDs, one per block in the file.
// The Nth DWORD is the total number of PCM samples that would be obtained
// by decoding the entire XMA file up to the end of block N. Hence, the
// block we want is the first one whose seek table entry is greater than S.
// (See the GetXmaBlockContainingSample helper function.)
//
// 2. Calculate which frame F within the block found above contains sample S.
// Since each frame decodes to 512 samples, this is straightforward. The
// first frame in the block produces samples X to X + 512, where X is the
// seek table entry for the prior block. So F is (S - X) / 512.
//
// 3. Find the bit offset within the block where frame F starts. Since frames
// are variable-sized, this can only be done by traversing all the frames in
// the block until we reach frame F. (See GetXmaFrameBitPosition.)
//
// 4. Frame F has four 128-sample subframes. To find the subframe containing S,
// we can use the formula (S % 512) / 128.
//
// In the case of multi-stream XMA files, sample S is a multichannel sample with
// parts coming from several frames, one per stream. To find all these frames,
// steps 2-4 need to be repeated for each stream N, using the knowledge that the
// first packets in a block are presented in stream order. The frame traversal
// in step 3 must be started at the first frame in the Nth packet of the block,
// which will be the first frame for stream N. (And the packet header will tell
// you the first frame's start position within the packet.)
//
// Step 1 can be performed using the GetXmaBlockContainingSample function below,
// and steps 2-4 by calling GetXmaDecodePositionForSample once for each stream.
