• Enhances Mix Loudness and Adds Harmonic Warmth • Full-Band and Two-Band Clipper in a Single Plugin • Quick, lightweight, and designed for effortless flexibility! • Precise Visual Metering for Fast Peak Control • Knee Curve Adjustment, from Super Soft to Hard • Shape Control of the Harmonic Profile • Dry/Wet Mix for a Natural, Balanced Sound • Low Latency with Optional Oversampling • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Clipper is designed to enhance your mix's loudness and add signature harmonic warmth. While it is based on a similar DSP architecture to the Clip processor in FAC Punchlab, it takes a different approach to clipping control, featuring an advanced user interface with precise metering to track and manage the peaks of the audio signal. The plugin also includes both a full-band clipper that processes the entire spectrum and a multi-band clipper, allowing you to independently clip low, high, or both frequency bands. This provides the flexibility to maintain transparent processing or experiment with creative adjustments, depending on your needs. Built with simplicity and flexibility in mind, FAC Clipper is quick, lightweight, and highly intuitive. The clean, streamlined interface lets you focus on what matters most; controlling the peak levels to maximize loudness while preserving clarity and avoiding the pumping effects often associated with heavily limited signals. Thanks to its precise waveform and level meters, using FAC Clipper is a breeze. Simply add the plugin to your track and adjust the input gain until the waveform meter reaches 0 dB. This gives you a clear view of the signal's dynamic range, making it easier to identify peaks. Next, set the ceiling just below the peaks you wish to control. You can also adjust the Knee parameter for smoother clipping and fine-tune the saturation to achieve the perfect warmth and character. Use the Mix parameter to blend the clipped signal with the original audio, allowing you to control the amount of clipping applied. This helps preserve the natural character of the sound while enhancing loudness and harmonic warmth. This is an AUv3 Effect and requires a compatible host to work The documentation is available at fredantoncorvest.com/FAC_Clipper.html
QuaDelay
This audio effect plugin creates unique stereo delay soundscapes using four independent delay lines. It offers advanced control over delay times, regeneration, modulation, and filtering for ambient and experimental audio textures. It can be used standalone or within compatible host applications.

QuaDelay Delay-Scaper (AUv3) QuaDelay is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic or GarageBand. Overview QuaDelay is a stereo delay effect that uses four independent delay lines to create interesting, and sometimes mesmerising "delay-scapes". QuaDelay is not your typical ping-pong delay, so if you're looking for tempo-sync'd quarter note triplets and dotted eighths, that's not really what QuaDelay is about. If on the other hand, you're interested in creating lush and ambient delay-based effects, this might just be the delay for you! Parameters Active - Toggles the effect On or Off. Note that when you set the effect to Off, you will still hear the delay repeats, but your input signal is no longer fed into the delay processing. This is a similar idea to the "trails" feature in many delay effects units and pedals. Delay - Sets the base delay time between 100ms and 8 seconds. Other delays will be heard at different times depending on the Ratios setting. Ratios - Changes how the other three delay line times are calculated. The 2:3:4 setting is probably the most obviously rhythmic, as it's based on the formula 1-(1/x) which produces the ratios of 50, 67 and 75%. These ratios are applied to the base delay time, so for a base delay time of 1000ms, one delay will occur after 1000ms and the others at 500ms, 667ms and 750ms. The Gold and Silver Ratios calculations are based on Prime numbers and the Golden and Silver Ratio in Mathematics. These calculations are the QuaDelay "secret sauce" ! Regen - Sets the regeneration or feedback of the delay repeats up to 100% "endless" repeats. Note that at high Regen levels, the sound will appear to degrade in quality and become "washed-out" or "murky". This is intentional, and an attempt to capture the sound of analog delays with limited fidelity. Compression and limiting are also applied internally to prevent excessive build-up, which can also result in a "crunchy" sound at extreme settings as the repeats are squashed each time they're layered on top of each other. Again, this tends to be a sonic characteristic of analog and tape-based delays. Mod - Applies a variable amount of stereo modulation to the delayed sound. LPF - Sets the cutoff frequency of a lowpass filter applied to the delay repeats. Reduce the LPF control for a darker echo sound. Dry - Sets how much of the dry / incoming signal is added to the output stage, and can be muted entirely if desired. Wet - Sets the overall level of the generated delay / effect. Reverb - Applies a large-sounding stereo-tastic reverb to the combined Dry and Wet output. Adding Reverb helps "smear" the delay repeats, creating ambient washes of sounds. By setting the Wet level to zero, you can use QuaDelay as a simple reverb effect. If the name sounds familiar, QuaDelay is an improved version of the QUADELAY module developed for Voltage Modular by Waverley Instruments.
