"Note Recognition - Note and Chord Pitch Detection" is a note and chord detection app for musicians, specifically designed for vocals, guitar, or piano players. This app listens to your music, analyzes its pitch, and converts it into an alternative sheet music format. It offers a range of functionalities, including detecting the notes and chords of your songs, validating the pitch of your voice, and allowing you to write notes and chords while playing along with your instrument.

The chord recognition algorithm of this app covers major chords, major 7th chords, minor chords, and minor 7th chords. While the detection won't extract 100% of the played notes and chords, it provides useful suggestions based on the quality of the signal. For the best results, it is recommended to have only one instrument playing at a time and to place your phone in front of your instrument or speakers to improve the detection quality.

Please note that the note and chord recognition algorithm performs complex mathematical calculations, so it may take some time to analyze your recorded audio. Additionally, the app is currently under development and will soon offer features such as audio import, tab sheets, and scale detection.

This app has been tested with guitars, pianos, and vocals, but it should work with any instrument as long as it plays notes above B1Hz).
