	If you only get a black screen with the white update line running down, it is very likely that the mixer is not setup correctly to use the built-in microphone of the FreeRunner. In this case, you can try to load capturehandset.state via alsa (alsactl -f capturehandset.state restore). It is possible that you already have the file on your device.

 Fourier does a realtime frequency analysis of recorded sound data and displays it on screen.
 The sampling rate is 44100 and it uses 256 samples to calculate the transform. The output is done in a sliding window fashion.
