Generation of Lt Rt
In the case when the playback system has analog or digital surround multi-channel capability, a down matrix from 5, 4, or 3 channel to Lt Rt may be desirable. In the case when the number of decoded audio channels exceeds 5, 4 or 3 respectively a first stage down mix to 5, 4 or 3 chs should be used as described above.
The down matrixing equations for 5-channel source audio to a two-channel Lt Rt playback system are given by:
Left left+0.7*center-0.7*(lt surround+rt surround)
Right=right+0.7*center+0.7*(lt surround+rt surround)
Embedded mixing to 2-channel
One concern arising from the proliferation of multi-channel audio systems is that most home systems presently have only two channel playback capability. To accommodate this a fixed 2-channel down matrix processes is commonly used following the multi-channel decoding stage. However, for music only applications the image quality etc. of the down matrixed signal may not match that of an equivalent stereo recording found on CD.
The concept of embedded mixing is to allow the producer to dynamically specify the matrixing coefficients within the audio frame itself. In this way the stereo down mix at the decoder may be better matched to a 2-channel playback environment.
CHS*2, 7-bit down mix indexes (MCOEFFS) are transmitted along with the multi-channel audio once in every frame. The indexes are converted to attenuation factors using a 7 bit LUT. The 2-ch down mix equations are as follows,
Left Ch=sum (MCOEFF[n]*Ch[n]) for n=1, CHS
Right Ch sum (MCOEFF[n+CHS]*Ch[n]) for n=1, CHS
where Ch(n) represents the subband samples in the (n)th audio channel.

/* You may be asking why I hard-code the instruction opcodes and don't
* use the normal VIS assembler mnenomics for the VIS instructions.
*
* The reason is that Sun, in their infinite wisdom, decided that a binary
* using a VIS instruction will cause it to be marked (in the ELF headers)
* as doing so, and this prevents the OS from loading such binaries if the
* current cpu doesn't have VIS. There is no way to easily override this
* behavior of the assembler that I am aware of.
*
* This totally defeats what libmpeg2 is trying to do which is allow a
* single binary to be created, and then detect the availability of VIS
* at runtime.
*
* I'm not saying that tainting the binary by default is bad, rather I'm
* saying that not providing a way to override this easily unnecessarily
* ties people's hands.
*
* Thus, we do the opcode encoding by hand and output 32-bit words in
* the assembler to keep the binary from becoming tainted.

/* The trick used in some of this file is the formula from the MMX
* motion comp code, which is:
*
* (x+y+1)>>1 == (x|y)-((x^y)>>1)
*
* This allows us to average 8 bytes at a time in a 64-bit FPU reg.
* We avoid overflows by masking before we do the shift, and we
* implement the shift by multiplying by 1/2 using mul8x16. So in
* VIS this is (assume 'x' is in f0, 'y' is in f2, a repeating mask
* of '0xfe' is in f4, a repeating mask of '0x7f' is in f6, and
* the value 0x80808080 is in f8):
*
* fxor f0, f2, f10
* fand f10, f4, f10
* fmul8x16 f8, f10, f10
* fand f10, f6, f10
* for f0, f2, f12
* fpsub16 f12, f10, f10

/**
* @file
* This is a demuxer for Sony OpenMG Music files
*
* Known file extensions: ".oma", "aa3"
* The format of such files consists of three parts:
* - "ea3" header carrying overall info and metadata.
* - "EA3" header is a Sony-specific header containing information about
* the OpenMG file: codec type (usually ATRAC, can also be MP3 or WMA),
* codec specific info (packet size, sample rate, channels and so on)
* and DRM related info (file encryption, content id).
* - Sound data organized in packets follow the EA3 header
* (can be encrypted using the Sony DRM!).
*
* LIMITATIONS: This version supports only plain (unencrypted) OMA files.
* If any DRM-protected (encrypted) file is encountered you will get the
* corresponding error message. Try to remove the encryption using any
* Sony software (for example SonicStage).
* CODEC SUPPORT: Only ATRAC3 codec is currently supported!
