Fred Corvest has announced fhe FAC Gravity pre-order, available for $6.99 for a limited time. The offer ends November 9th.
FAC Gravity AUv3 Plugin is a frequency shifter for creating Barberpole and Shepard style glissandos, spectral illusions, stereo rotation, chorusing, phasing, evolving echoes, infinite cosmic spaces, and all the combinations you’ll make
The plugin gives you two ways to process the audio source. In Stereo mode, each channel is shifted independently, with a Ratio control determining how closely their frequency shifts align. In Mono mode, FAC Gravity extends the internal quadrature processing to create a wide stereo image from the mono source.
The frequency shift can move up or down, from subtle to more extreme spectral transformations. You can set the amount in Hz for classic Bode-style frequency shifting, make it follow your host tempo for rhythmic patterns, or even control it from MIDI notes for a more hands-on approach.
A new dimension appears when you let the shifter feed back into itself with Spiral, a customizable loop with delay, blur, filtering, and different characters that shape how the sound circles, smears, interacts, and evolves over time. The result can range from bubbling textures to infinite sustained tones and noisy analog self-oscillation. Each character takes the feedback somewhere different.
Features include:
- Barberpole glissandos, spectral illusions, rotating stereo, evolving echoes
- Dual Frequency Shifting, or Mono Shifting with Quadrature Stereo Widening
- Organic Spiral Loop, from gentle feedback to pure analog self-oscillatior
- Integrated delay, diffusion blur, and independent low/high filtering
- Modulation matrix, multi-source envelope follower
- LFO with classic waveforms and random spline
- Spinning modulation to rotate and animate the stereo field
- Tempo-synced or MIDI-driven Frequency Shift, LFO, and Delay
- Dry/Wet mix, optional limiting, and goniometer visualization
- Advanced Responsive Design, portrait and landscape views
- Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro
