From NCH Software:
TwelveKeys is an aid to assist musicians in learning and transcribing music recordings. It is able to accurately detect notes in both simple single instrument recordings as well as complex polyphonic compositions. Features: ~ Analyses and graphs monotone and polyphonic audio recordings ~ Play your recording and watch the notes go past in real time ~ Rip files from CDs ~ Configurable settings to get the clearest graphs possible ~ Support for foot pedals to allow hands free operation ~ Slow down or speed up recordings without changing the pitch ~ Tone enabled piano keyboard to assist in identifying notes ~ Stereo channel separation ~ Ability to loop a section of the recording ~ Quick and easy operation.
The program is not highly complicated, have not used it properly yet but intend to try it out shortly. The secret of success is either highly complicated for the professionals or basic for those who are amateurs.
Have not tried it properly yet so cannot venture an opinion, will offer a summary if you would like one at a later stage.
An excellent work and deserves all the success you should receive.;
