Mono compatibility remains a very important part of music production, because music is often played back in mono, or with a poorly reproduced stereo. Think about shops, workplaces and parties. There are a variety of loudspeaker setups. Many, if not most of them, are less than ideal. Even a high-end surround system may come with only 1 loudspeaker for the bass (a subwoofer). This makes sense, as human hearing can barely distinguish the direction of the lowest frequencies anyway. But a professional audio production usually has to shine in all these cases.

 

This Stereoizer is designed to either widen an exsisting stereo signal, or turn a complete mono-sound into stereo. It works by adding a phase inverted chorus to the dry signal. Because of this, it will be completely inaudible (and thus, mono compatible) when both the LEFT and RIGHT channels are mixed together, as is often the case in mono playback. It may however introduce flanging effects, when listening to each channel separately (either LEFT or RIGHT). This may be desired or not, so I advise you to always check how your production holds up under different circumstances. In most cases, you can avoid unwanted flanging by adjusting lfo-depth and pre-delay.

 

Here are some examples (first you hear the unprocessed sound, then the stereoizer comes on)
