Stereo Synthesizer

This routine efforts to cheer up mono audio resources by replicating a music indication. It does this by changing certain wavelengths between left and right to deceive the ear. It can often generate a acceptable concept music audio to bring some level to otherwise flat sessions. Of course, there is no way to generate real music audio from a simply mono source unless the workstation had a way to tell which route the unique audio came from, but an impression is generally enough for all but the dedicated audiophile.
