What's the best (free, online) music transcription program? Not notation software, but transcription (or pitches) from audio recordings.

I’m transcribing a very complicated folk tune, full of intricate, fast ornaments. I’m able to do it, and I’m using Express Scribe among other things to slow it down while maintaining pitch. But I can’t help but think on the mechanical level that there are programs that could just spew out the frequencies without me doing that grunt work, especially since it’s a single-line solo recording and the guy sings pretty crisply (of course I know I’ll have to do a lot of clean-up in the notation). I Googled and see a few online (ie seventh string)... but not sure about it. Does anyone have experience with them?

I also have Finale, but it seems that only works with MIDI/synth input, which I don’t have set up at the moment. Plus, if already knew the notes to play them on the keyboard I’d just write it down!

Thanks.
