HRTF filter updates:
- Bass compensation gain corrected (which was set too low), now the
sound should be even more transparent
- A (unified) dual axes active matrix decoder with adaptive steering
- capable of decoding matrix surround encoded inputs, with stereo rear
- capable of decoding matrix encoded rear center
- Purely stereo mixing without unneccessary rear filter calculations
- The decoding structure message is moved, because at the old place it
gave incorrect messages.
