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. + + + +/*************************************************************************** + * XMA constants + ***************************************************************************/ + +// Size of the PCM samples produced by the XMA decoder +#define XMA_OUTPUT_SAMPLE_BYTES 2u +#define XMA_OUTPUT_SAMPLE_BITS (XMA_OUTPUT_SAMPLE_BYTES * 8u) + +// Size of an XMA packet +#define XMA_BYTES_PER_PACKET 2048u +#define XMA_BITS_PER_PACKET (XMA_BYTES_PER_PACKET * 8u) + +// Size of an XMA packet header +#define XMA_PACKET_HEADER_BYTES 4u +#define XMA_PACKET_HEADER_BITS (XMA_PACKET_HEADER_BYTES * 8u) + +// Sample blocks in a decoded XMA frame +#define XMA_SAMPLES_PER_FRAME 512u + +// Sample blocks in a decoded XMA subframe +#define XMA_SAMPLES_PER_SUBFRAME 128u + +// Maximum encoded data that can be submitted to the XMA decoder at a time +#define XMA_READBUFFER_MAX_PACKETS 4095u +#define XMA_READBUFFER_MAX_BYTES (XMA_READBUFFER_MAX_PACKETS * XMA_BYTES_PER_PACKET) + +// Maximum size allowed for the XMA decoder's output buffers +#define XMA_WRITEBUFFER_MAX_BYTES (31u * 256u) + +// Required byte alignment of the XMA decoder's output buffers +#define XMA_WRITEBUFFER_BYTE_ALIGNMENT 256u + +// Decode chunk sizes for the XMA_PLAYBACK_INIT.subframesToDecode field +#define XMA_MIN_SUBFRAMES_TO_DECODE 1u +#define XMA_MAX_SUBFRAMES_TO_DECODE 8u +#define XMA_OPTIMAL_SUBFRAMES_TO_DECODE 4u + +// LoopCount<255 means finite repetitions; LoopCount=255 means infinite looping +#define XMA_MAX_LOOPCOUNT 254u +#define XMA_INFINITE_LOOP 255u + + + +/*************************************************************************** + * XMA format structures + ***************************************************************************/ + +// The currently recommended way to express format information for XMA2 files +// is the XMA2WAVEFORMATEX structure.
