Note Recognizer - A 440 Hz

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.

Your microphone detects your voice or instrument, and then converts that sound into an electrical signal. That signal is then interpreted by our app and the frequency of that sound is deciphered and displayed along with the corresponding musical note.

Very useful for singers who need to find the right starting note of a song. Or if you want to know the key of a song; sing the tonic, and you get the note name of the key.

What instruments will this pitch detector work with? - Our Note Recognizer app will work with most instruments and vocals.

Recognition range: E2 - G7. Whistling above this range wil not be recognized.

The quality of the microphone of your device may influence the performance of the app. If you looking for vocal training and do you have little or no singing experience or voice training? Then we recommend Note Recognizer.
