Peter Meerwald 555388ebba remap: Add special remapping case which just re-arranges channels ... Input channels may just be copied to output channels, no mixing; this avoids the generic (slow) matrix remapping code in cases where channels are dropped or reordered. This makes use of the remap struct state introduced earlier. on Intel Core i7-870 @ 2.93 GHz (GCC 4.6, 64-bit): Checking special remap (s16, stereo rearrange) func: 126117 usec (avg: 1261.17, min = 1150, max = 2111, stddev = 117.332). orig: 190509 usec (avg: 1905.09, min = 1807, max = 2402, stddev = 100.984).
