* More HRTF enhancementsGravatar henry2005-04-11
| | | | | | | | | | | | | | | | | | | | | - a passive locking mechanism to enable the matrix to switch between active and passive mode, which enhances the stereo image. - a center front cancellation algorithm that damps the cross-talk if the sound is coming predominantly from center (e.g. if there is dialogue). These two new features should enhance the quality of surround downmix noticeably. Also a correction to the active gain control is included. The previous implementation of Lt + Rt/Lt - Rt AGC should be fine in most cases, but the calculation was inconsistent (gain unitarity is not guaranteed to be preserved).

* HRTF filter updates:Gravatar henry2005-04-10
| | | | | | | | | | | | | | | | - 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.
