Mono to stereo

This instrument converts from mono to stereo not by simply copying one mono channel into two identical stereo channels (in this case the sound would not differ from mono). The difference in time, frequency and amplitude is added to one of the channels, thus creating a pseudo-stereo that sounds like a real stereo.

Stereo to mono

Two stereo channels simply mix and fit into one mono channel.
