MIMO-XTC-SH

Animated gif overview over the MIMO crosstalk canceler in spherical harmonics for acoustically coupled spherical loudspeaker arrays from my DAGA08 talk. Using these filters, the membrane velocities decomposed into spherical harmonic patterns can be individually controlled. (click on original!)

Dolby surround sound formats

When we designate the maximum number of speakers/channels for each format, such as 5.1 or 6.1, we're referring to the number of front, center, rear, and possibly center-rear speakers (the .1 refers to the subwoofer) that the format can use. Stereo, a.k.a. 2.0, is a two-channel format. Check out the diagram to see how they are set up in a room.
