I do know that you could get such functionality from an FFT package
such as FFTW (those bars are not actually a waveform, but indicators
for frequency ranges):
http://www.fftw.org
Though this one is very simple (only 8 bars, whereas some FFTs I have
done needed about 10,000 every 0.25 seconds), FFTs may still be far
more complicated than what you want. The FFTW package is open-source
though, and I'd be happy to give you a few tips on implementation if
necessary.

anyone know of any open-source app that shows how to create those bars
