Soniformer is a spectral mastering dynamics processor plug-in for professional music production applications, available in AudioUnit, VST and VST3 plugin formats (including native 64-bit support), for Mac OS X (v10.6 and later), and Windows computers.

Every parameter in Soniformer is defined by means of a graphic envelope which is freely-modifiable and which may contain unlimited number of control points. Beside usual threshold, attack, release and compression/expander ratio parameters Soniformer offers a user control over "stereo width" and "panning" parameters designed to make Soniformer an effective tool for stereo field adjustments.
