Note Recognition

Play an instrument or sing into the microphone and convert it into sheet music.

"Note Recognition & Chord Detection: Music to Notes" is a note and chord detector app and converts music to notes. It works with pitch detection and frequency analysis and is perfect for musicians (especially vocalists and guitar or piano players). It listens to your music, analyzes it's pitch and converts your music back into an alternative sheet music. You can use it to detect the notes and chords of your songs, validate the pitch of your voice, sing into the microphone and use it as a vocal trainer or to write notes and chords while playing along with your guitar (or whichever instrument you are playing).

The chord recognition algorithm includes the following chords (all chords majorly tested with the guitar):

- Major chords

- Major 7th chords

- Minor chords

- Minor 7th chords

The detection won't extract 100% of the played notes and chords but depending on the quality of the signal it will give you useful suggests. Because the app can't separate instruments you will get the best results if just one instrument is playing at a time or if you sing without any background music. Also, you should place your phone in front of your instrument, your voice or your speakers to improve the detection quality.

Please note that the note and chord recognition algorithm performs intense mathematical calculations and it will take some time to analyze your recorded audio.

Further features that are currently under development and coming soon:

- Audio Import

- Tab sheets

- Scale detection

Having bad detection results sometimes? Try to open the settings and adjust the detail level at which it shall convert music to notes.

This note and chord detector was tested with guitar, piano and vocal but should work with every instrument as long as it plays notes above B1 (61,7 Hz) and convert music to notes.
