The quality of echo cancellation in audio teleconferencing
could stand a lot of improvement. Imagine something similar
to a Polycom Soundstation but with five legs instead of
three (it would look like a big starfish). Equip it with USB and IEEE 1394 ports. Distribute several small microphones and
along the legs. Multiplex the acoustic input/
output streams onto the IEEE 1394. Connect to a Beowulf
cluster in an adjacent room. The Beowulf cluster cleans up
echos and employs beamforming and tags the resulting audio stream with information about the location of the speaker in
the room. Beamform the loudspeaker output so that multiple
semi-private conversations can take place. Use the Beowulf cluster for company R&D when no teleconferences are scheduled.

||This isn't geek, this is gibberish.
||OK, that's a little harsh. But
the references to Beowulf
clusters, IEEE 1394, and USB are
completely gratuitous (read:
stupid). The specification of 5
legs (rather than 3 or 15 or any
other number) is also gratuitous
and arbitrary (read: stupid).
||If you delete all that, what's
left is "use an array of
microphones, an array of speakers,
and beamforming to transmit
spatially keyed audio for
||Regardless, of the relevance of this idea HalfBakery is definitely the wrong place for it IMHO. Try ShouldExist if you want legitimate feedback.
||egnor: as I understand it, the big difference is that many of the ideas we come up with should not exist.
||i think of Halfbakery is a place to pose half-baked ideas. Meaning not fully thought through. It doesn't mean they can't be valid. Ideas you have off the top of your head valid, invalid, funny, serious, etc. This one looks like someone is trolling for Venture Capital. Plus the idea name sucks.
