Party Organ is an app that causes the flash on your device to flash along to the music. Unlike other similar apps, Party Organ does not need any time to recognize the song, instead it INSTANTLY picks up the song and starts flashing along. Also, you do NOT need to use music from your music library, any ambient music will work!
As well as flashing along, a beautiful visual graph is shown on screen that shows the music as picked up by the microphone allowing you to see what the phone hears. On screen controls allow you to control the sensitivity as well as the frequency response of the light.
To use the app, simply set your phone next to an audio source such as a speaker and open the app. The light will instantly start flashing along!
