TwelveKeys is a music transcription software that helps musicians learn and transcribe recordings. It is designed to assist in recognizing different notes, rhythms, and chords to improve the learning process.

This amazing music software comes with a variety of features that make transcription easier than ever. For one, it analyses and graphs monotone and polyphonic audio recordings. You can also play your recording and watch the notes go past in real-time! Moreover, TwelveKeys provides you with the ability to rip files from CDs, and configurable settings to get the clearest graphs possible.
For enhanced usability, this music software has support for foot pedals to allow hands-free operation. You can also slow down or speed up recordings without changing the pitch, and use the tone-enabled piano keyboard to assist in identifying notes. Other features include stereo channel separation, the ability to loop a section of the recording, and quick and easy operation.
