A Spatializer for Monaural Audio

ADI's SuperPhat Spatializer works well with stereo program material and is especially useful with headphones. It doesn't do much, however, for monaural audio fed to both its inputs. Here's a way to get a "spatial" sound from a mono signal (for example, from a Zoom call). It replaces the "in your head" effect often heard through headphones with a sweet room-like ambience.

The mono input arriving from the left is phase-shifted into two signals via the Hilbert Transform. The Spatializer works nicely with this pseudo-stereo input. Adjust Delay1 to center the sound field in your headphones -- otherwise the sound favors one side or the other. The effect is quite natural, it feels like you're in a live setting rather than listening to a remote meeting through cans. In fact, you may get used to it and thus forget it until you switch it OFF -- you'll want to turn it back ON. Have fun with it.

Best regards,
