This program is a very simple linear system simulator, using which you can try out the effects of various impulse responses on any input signal. Additionally, the program is able to cross-correlate the two signals.
This program is tested using Ruby 1.9.2. It also depends on the gem rubygame, the libraries SDL, SDL_gfx and SDL_ttf.
Click on one of the two input waveforms to focus it, or press Tab to change the focus. Use the arrow keys to change the waveforms - the result is immediately visible on the output. You can also right click a waveform and enter an equation in the console window. Press Space to switch between convolution and correlation mode.
