Oh well.
Right, but I need to have a hands free headset so I can listen to music, so it's not a second piece of hardware. Admittedly, I could put a piece of tape on the cord every inch and get the same effect... I wonder if there's some other application of sending out a chirp and recording it. Maybe the FR could use echo to characterize acoustic environments. Then it would know if you've left it in a drawer, pocket, car, concert hall, etc... There's also echo cancellation, which the FR desperately needs, and is a similar trick. > > So the theory seems plausible. When I get my Freerunner (when are they back > in stock?!) I'll have to do some testing. Thanks for the input, folks. You could probably develop it on a linux laptop and alsa. For this app, the main difference between the platforms is that the FR doesn't have a floating point unit, and it uses a different microphone jack. -Rusty > > -Charles > > > > ------------------------------------------------------------------------ > > _______________________________________________ > Openmoko community mailing list > community@lists.openmoko.org > http://lists.openmoko.org/mailman/listinfo/community _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
