MS SongSmith doesn't provide transcription, either, but the underlying
processing could probably do it.   At least it sure seems like it.

If you haven't heard of SongSmith, it's an MS application whose
function is to automatically put a band or orchestra behind a vocal
track.  It's pretty awful at it, but there are a few websites that
have interesting collections of classic songs where the vocal/melody
was isolated and run through SongSmith, like this one:

Roxanne is classic.

I like "Creep" on here, too:

It seems like a transcription function would have to be under there
somewhere.

Thanks, problem solved.

There is already an application out there that does this: transcribe

Start with the basics. Hopefully, in 3..4 years you will be able to 
approach the problem.

I'm trying to get a signal being recorded from a microphone to be converted
to a list of musical notes played. 

I am new at this, and have gotten results from getting and audio signal
with pymedia or the sound card directly, then using Numpy's FFT I have
gotten what I think is a list of signal strengths at various frequencies.
It, however, does not seem to be verry accurate. 

I was wondering if this is the process to use, or I am on the wrong track
all together.
