If I played a CD, would Noteworthy give me the standard notation layout?
No. AFAIK, there is NO program that you can input multi-instrument wav or mp3 files hand have it output notation. OTOH, there are several programs that will convert a simple one-instrument wav file to midi....
I tried several such demo programs last year which didn't pan out. Even the best of them needed so much manual cleaning up (using a notation program) that it would have been far quicker to manually input things.
Also, the better programs take an incredible amount of time to "set up". You have to play the instrument into the program to "calibrate" things, much like the older (and some still current) voice recognition programs require. The programs need to create a basis by analyzing various pitches of notes at certain sound levels for beginning attack, sustain and decay so that it can correctly recognize the note pitch and duration.
Even with all that, I found that the accuracy of the output varied greatly upon the type of instrument. I compared results from concertina, piano, fiddle, and electronic keyboard by slowly playing a simple scale. The software outputted midi fairly well of the keyboard, fairly poorly of the concertina, poorer yet of the piano, and the fiddle was almost complete mush.
It seems that the problem has a lot to do with the overtones created by the instrument. For instance, trying to recognize the single note of middle C on the piano results in about 3 notes recognized (the octave above, the 5th above that, the octave above that). Recognizing the C a couple octaves lower results in about 10 notes (a lot more overtones). If you played consecutive notes the decay of previous ones gets in the way and causes all sorts of cleanup problems.
I found it near impossible to separate chords out as the overtones made hash out of the results. I can't imagine how a multi-instrument recording should come out when these programs have such underwhelming output using only single notes from a single instrument.
Has any one else had experience with sound recognition software? I'm sure things have progressed since I tried them out last year though at the rate they're going I'm afraid it'll be quite some time before we'll have a reasonably viable program.

I have wanted this for a long time. Someone told me that Cakewalk did that, but I was watching him try to play his instrument and have it output standard notation and he was having a hard time.
Also, I believe Cakewalk is a lot more expensive than Noteworthy.
I'm not very familiar with Cakewalk but would be very surprised if it has the capacity to recognize sound files and convert them to notation (or even midi). Cakewalk produces many software programs which go for as much as $700.
