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.

Needed Libraries
Fourier uses libsdl for graphics output and libfftw3 for the frequency analysis. You need to additionally install libfftw3 for FDOM, a suitable package can be downloaded here: libfftw3-3_3.1.2-r1_armv4t.ipk (8.5 KB) (obtained from http://www.angstrom-distribution.org/feeds/2007/ipk/glibc/armv4t/base/libfftw3-3_3.1.2-r1_armv4t.ipk)
opkg install http://www.angstrom-distribution.org/feeds/2007/ipk/glibc/armv4t/base/libfftw3-3_3.1.2-r1_armv4t.ipk
libsdl-1.2-0
