Hi ya fokes! I'm not strong in sound formats [lol]but could you tell me how could i make a .mdi format out of mp3,wav ,audio etc .I am intereasted in a freeware,if there's any.Also some good sources (you've tried)where i could learn more about sound formats would be very appreciated. Thanks for your help.

There is no reliable audio -> MIDI converter. Many people have tried, but ultimately, the end result is extremely inaccurate, even with monophonic recordings. So, don't bother. If you absolutely need something transcribed, you'll need to learn how to do it yourself by ear.
