About
The Note Recognizer - A 440 Hz easily analyses the pitch frequency that you sing or play, and gives the corresponding note name quickly and accurately. Works great for vocals, piano, guitar, violin, and more! This 440 Hz tone is A in the musical scale. This tone is good for tuning or keeping a reference to A. The Sine wave has no overtones so it is sometime called pure as it is only the fundamental frequency. Play your musical idea on an instrument and have it transformed to musical notation.
