Schlap is a characterful, colourful and aggressive sounding program-dependent AUv3, IAA & standalone compressor. It takes inspiration from hardware RMS compressors of the past and evolves them into a modern setting. If you want your tracks to be energetic, in-your-face and bold, make ‘em ‘Schlap’. The compressor uses a program-dependent attack and release influenced by old hardware which makes the compression sound characterful and dynamic. The RMS detection means that Schlap detects the average loudness of a signal, resulting in sudden short peaks being uncompressed so that they can attack hard and sound heavy hitting. Also inherently in RMS detection, there is a slight delay in compression which allows the initial, early transients to sneak through uncompressed so they keep their punch. You’ve got a safe, controlled track you think you’re happy with, but you have to ask yourself… ‘Does it Schlap?’ Schlap is both a stand-alone application as well as an AUv3 plugin, meaning it works within iOS and iPadOS hosts such as GarageBand.
FAC Clipper
This audio plugin enhances mix loudness and adds harmonic warmth with flexible full-band and two-band clipping. It offers precise visual metering, adjustable knee curves, and a dry/wet mix for balanced sound. Designed for quick, intuitive peak control on iOS, macOS, and Vision Pro.

• 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
