Sure, but I'm not sure what I could do with it after I recorded it? I've actually made MP3s of our playing as a group before, too. But they are pretty big...couple of MBs.
I'm pretty bad at fiddle - I've only been playing since April. It's tuned the same as mandolin so I'm probably farther along than most would be at four months, but still pretty bad...
You have a recording of you playing whistle? I'd like to hear it!
