Piano Transcription

Piano Transcription is a versatile application designed to assist users in learning and playing MIDI chords on a real piano through a real-time transcription feature. When you play notes on your piano, the app recognizes these and highlights them accordingly. Successfully playing all notes of a chord prompts it to move on to the next chord, enhancing the learning process.

The application supports not only MIDI files but also a wide range of other audio formats like MP3 and MP4, and can even handle the audio streams from video formats. Whether you're looking to work with a pre-existing MIDI file or want to capture a new piece directly through a microphone, it facilitates these needs. For each session, it transcribes audio and saves it as a MIDI file.

Unique among its features is the ability to transcribe polyphonic piano pieces from audio or video into MIDI format. However, it does not extract individual instrument tracks, combining all transcribed notes into one part. The transcription accuracy is noted to be around 75% for solo piano pieces, with performance depending on the complexity of the piece being played.

For users looking to disable non-piano tracks like percussion, automatic filtering is applied to remove these from the tracks in MIDI or Karaoke files. This tool is especially useful for ensuring that the focus remains on the piano notes alone.

In its operation, it offers a user-friendly interface where tapping different areas of the screen allows for real-time playing or navigation through chords. It also highlights correctly played notes in green and mistakes in red, which is especially helpful in noisy environments where sound recognition may be affected. For optimal note recognition, users should operate in quiet settings or utilize headphones with their electric piano for better accuracy.

Piano Transcription not only offers extensive file compatibility and robust transcription capabilities but also engages users in an interactive learning experience, making it a sophisticated tool for both aspiring and seasoned pianists.
