I don't mean to sound like a wowser or a troll, as this sounds like kind of a cool project, but ahh, I'd say stick with the headphones.

It's bad enough that people want to start blasting synthesized engine sounds out of (thankfully) quieter electric and hybrid vehicles. just a thought -m _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
