Listen ideal crossover on headphones

This experiment is try and listen if crossover has any sound in ideal case. Ideal case her means that signal is split into high and low passed signals and then are summed back together all in digital domain. With real loudspeakers the split would happen in digital or eletcric domain and summing would be in acoustic domain.

There are some 2nd and 4th order Linkwitz–Riley filters available to listen as well as few 3rd order Butterworth filters that have 90 degree phase difference.

Hit Start to enable browser start audio. Wait for sound and filter selection to appear, might take few seconds.

Adjust sound volume, 0 - 10. Volume is initially set to 5 to protect your ears. You also need to select an audio source before sound starts.
