Synesthesia makes listening to music a colorful experience and is a wonderful mood light and soft night light when you want to calm down. Do you want to see colors when playing certain tones like people with synesthesia / chromestesia do? The app "Synesthesia - See the music in colors" enables you to experience music in color as well. Whether you use it to train you perfect pitch, to help you remember melodies or just for entertainment as a light organ while listening to your favorite songs - Synesthesia helps you to see the current pitch in colors. To experience the colors simply allow the app to access the microphone on the first start and then play your instrument or a song, sing, ... or just enjoy many color changing patterns even without music as a mood light or night light. Please note: People with synesthesia may experiences different colors for the same pitch. The app therefore uses it's own color scale (each musical note C displays a red color for example). Some of our users use the app as an replacement for their old light organs ... so that should work very well ;-) If you like music apps be sure to check out our other apps as well -> Piano Champion, Guitar Champion, Drum Champion, Voice Back .... and many more to come
