MacMobile http://www.francoborgo.info/MacMobile/Voice.html I used a LapelMic and iMic from Griffin Technology. At 60 mph voice recognition degrade quite a lot. Technical problems: 1- At higher speed, I record an audio record with Apple QuickTime. The sound recorded is almost only low frequency from wind noise. I would be happy if anybody could guide me to a simple High Pass Filter. 2- I would be even better to have a two microphones set for noise canceling. One oriented toward my voice and the other one to record ambient noise and then subtract the two. I heard that Logitech is selling one at 20$. I am not sure about the quality of this microphone and it’s noise canceling power. Any Suggestion ?
