Stereo Imaging and Tone Control
The Tune control adapts the upmix to the character of the source, whether it is a voice, a guitar or a drum mic. High- and low-pass filters let you limit which parts of the spectrum are widened, and the diffusion mode can be switched to change how the signal spreads.
Fuse Audio Labs says the plugin is designed to widen sound without adding metallic or hollow tones, and to keep the output phase-coherent. Mono compatibility is preserved, so the result should still hold up when the mix is folded down.
