Plugin Alliance Releases Fault Plug-In

Versatile processor uses pitch and frequency shifters, filtered delays and multiple freely assignable modulators to polish sound or completely mutate tracks.

Plugin Alliance in Santa Cruz, Calif., announces the release of Unfiltered Audio’s Fault ($TBA) processing plug-in, featuring a stereo frequency shifter and delay. Fault’s processors can be used sparingly to improve the quality of poorly recorded tracks or, at extreme settings, to completely transform them into something that’s unrecognizable from the original. Unfiltered Audio plug-ins, as well as all other Plugin Alliance products, are provided in AAX native, VST and Audio Units formats for Mac OS 10.6 or higher and Windows 7 through 10. 

Three main processors form the core of Fault’s extensive toolkit. The stereo Frequency Shifter can be used in ring-modulator mode to add missing spectra to poorly recorded drum and percussion tracks—restoring detail and impact—or modulated by high-resolution FM controls to create beautiful and discordant sounds alike on pitched instruments. The pristine, dual-channel Pitch Shifters execute fractional-semitone to full-octave shifts—up or down—without introducing the artifacts that other pitch shifters suffer from. Two independent Delays can be synchronized to the host’s tempo and use filters and discrete dual-channel or cross-channel feedback to add immersive depth.

Six completely customizable feedback paths, three each for the Frequency Shifter and Delays, create complex textures. Fault also includes Unfiltered Audio’s flagship modulation system, which provides six freely assignable modulators—sine LFO, sawtooth/triangle LFO, square-wave LFO, input follower, sample-and-hold noise, and a macro control knob—with drag-and-drop virtual patching to every control knob and switch in the plug-in’s efficient GUI. Mid-side processing adjusts the stereo image from mono to super-wide. A soft clipper and sampling-rate crusher add lo-fi character. A Dry/Wet mix control provides parallel processing, dialing in the perfect amount of effect without having to route tracks to auxes.

Fault can also create ping-pong delays, chorus, flanging, octaver, tape recorder-style vari-speed ADT effects and more.

All Plugin Alliance products are available as fully functional 14-day demos at
