Does the idea of Audio Files (not to large) appeal to you in the aid of mechanical diagnosis?
What I had in mind is possibly members sending in a recording of conditions that produce a noticeable noise.
This could be accomplished via freeware/shareware available to download off the web for free, a recorder such as hand held cassette($20) or something more sophisticated such as a MiniDisk player/recorder ($200) and a microphone. Then via the software, the audio could be converted into a wav file (for example) that can be listened to by you after uploaded to the web.
Basically, would this method help and would you guys be receptive to the idea???
