Rave Frequency

This application turns your androids microphone signals into visuals. It is simple yet can be fun to play with it. Works even better, if you use multiple androids with different frequency settings.
It may be suitable for rave parties, but it is better for private parties, with dark atmosphere. If you and your friends have this application, then you can combine modes, put phones around room and enjoy the atmosphere.

This app responds to audio frequency.
You can also get Rave Frequency, if you wish that this application would respond to audio amplitude.

Because of Android limitations, refresh rate of this application is 12Hz and latency is around 100ms.
