- * 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.
