Visualised Audio can classify single notes using monophonic pitch detection and visualise notes and harmonies. Visualised Audio can help you fine tune your playing technique by showing you how close to pitch you are. Visualised Audio can show you all the beautiful harmonics that your instrument is creating. Is there a difference between your $100 instrument and your $2000 instrument? Visualised Audio is a fun tool to use while you're practising scales as it's showing you what the notes look like and which harmonics lie on top of the fundamental pitch. If your instrument is creating strong harmonics you can use the slider at the bottom make the application less sensitive and thus help it classify the fundamental pitch instead of the harmonic. Left on the slider means less sensitive to harmonics. The default value should be good for most people. Since the application makes heavy use of the microphone it needs both access to it as well as a relatively quiet environment. Note - The classified note detected by the app Error - The deviation from the note in cents Clarity - How pure the signal is. This has nothing to do with error.
