I'm working on a stereo system for my motorcycle helmet so I can listen to music from my iPod while I'm motoring down the road. 5 watt amplifiers provide the music power I need, problem is I have to constantly diddle the volume of the MP3 player to adjust for wind noise. Seems straight forward enough to convert wind noise to DC using a mike and amp and integrator, but I need help with making a LINEAR voltage controlled volume control to use between the iPod and the amp. Thanks for any help or suggestions anyone can offer.
