AudioHertz

AudioHertz est une FFT de l'onde sonore.

AudioHertz is just for fun.

It picks up audio signal from microphone and displays as a spectrum wheel of frequencies at real time.

Three ranges of frequency spectrum, 43Hz - 22KHz, 21.5Hz – 11KHz, and 10.8Hz – 5.5KHz, are selectable by tapping on the screen.

The frequencies are displayed from the lowest to the highest counterclockwise starting at the 3 o’clock position, and also in color from red through green to blue.

If, for a period of short of time, no active audio (music, vocal or loud noise) has been picked up by the microphone, some bugs will show up and approach the spectrum wheel. Think of the scene as cockroaches take over your kitchen in the night.

The spectrum wheel will discharge an electric shock and kill the bugs when they come in contact with the wheel, and releasing a flashing lightning with a bang. If the media sound volume is on, the bang (as a noise) will be recursively picked up by the app and scare off other bugs a little bit.

Have fun watching!
