I released a realtime Music-visualization-program (my master's thesis) on http://sonasound.sf.net.
It's probably more of academic use at the moment. Licensed under GPL.
Maybe there is some interest.
Features are:
- Waveform-Display
- short-time-spectrum
- sonogram
- spectrum-generation switchable between lpc and fft
- Major kinds of windowing functions choosable
- Different kinds of windowing functions are directly comparable via live-switching
- Overlap of 50% can be switched on and off without stopping
- Buffer-Size and FFT-Size freely adjustable
- All Displays work from soundfile while playing or direct live-input from soundcard
- Comparison of different spectrum-generation-methods via multiple instances fo SonaSound possible
Libraries needed: - fftw (www.fftw.org) - glib >= 1.2 - gtk >= 1.2 - gtkglarea - GL - GLU - portaudio (www.portaudio.com) (Yes, I know, switching to JACK might help) - sndfile >= 1.0
There are many features I would like to add and a few not-so-good-features I'd like to clean up.
Have fun*
