auch is a gnuplot-like program to visualize harmonics and test the effect of digital and analog filters. This tool was originally made to see what the SoundBlaster X-FI soundcard can do. I wanted to... * Compare original audio (.wav files) with processed audio and see the effect of EAX and SVM,... * See the difference between MIDI - and real instruments. Why 'audio--checker'? Because when you see music as sounds over time, you have a surface: one direction is time, other is 'frequency'. Strike a note on a piano and you get a clear line in time. Playing melodious music gets you vertical lines of the harmonics.
