WaveFolder vs FAC Fizzica
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
WaveFolder
This audio effect app adds harmonics to sound by folding waveforms. It's ideal for enhancing synth leads, transforming drum loops, and creating ambient drones. Customize folding thresholds and modulation for unique sound design.
- Wave folding distortion
- Harmonic addition
- Adjustable folding thresholds
- Modulation of folding amount and symmetry
- Tempo-based or free-running modulators
- Built-in wave shaper
- Color themes

WaveFolder is a simple Wave Folding Audio Unit Extension. Wave Folding is an interesting distortion effect that adds harmonics to the original signal by folding the waveform back on itself when it exceeds a clipping threshold. WaveFolder is great for adding spice to monophonic synth leads and rhythmic, tempo based modulations can turn drum loops into totally new entities, while long, slow, free running modulations are perfect for dirty ambient drones. WaveFolder lets you set the folding thresholds and modulate the folding amount and symmetry with tempo based or free running modulators. WaveFolder also includes a wave shaper to add even more interest. There is also a short built-in manual and a selection of colour themes.
FAC Fizzica
This app infuses audio with dynamic digital textures and movement through audio-rate modulation. It features an integrated envelope follower for expressive sound shaping and supports various modulation sources for unique sonic transformations. Optimize your workflow with an intuitive XY control pad and visual spectrum display.
- Digital texture infusion
- Integrated envelope follower
- Audio-rate modulation

• Infuse your sound with digital artifact textures • Integrated envelope follower for dynamic sound expression • Supports noises, oscillators, and internal/external audio modulation models • Side mix control to balance between fully processed signal and sidebands • Sidechain support: external envelope follower and audio model • Optimized workflow with an easy-to-use XY control pad • Spectrum display of the output signal • MIDI control: Envelope via CC, main frequency and filter cutoff via notes • Extended version of FAC Punchlab's Fizz module • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro Infuse your sound with dynamic digital textures and movement using audio-rate modulation. FAC Fizzica extends FAC Punchlab's Fizz module, maintaining its intuitive design while introducing advanced features for extensive sound shaping. FAC Fizzica is your go-to solution for achieving a vintage lo-fi aesthetic and enhancing audio by adding digital noise artifacts that dynamically respond to your audio input. Ideal for refining basslines, pads, drum loops, and any elements requiring organic and expressive transformations. The plugin offers dynamic expression thanks to its envelope follower, an essential processor in sound design that effectively transforms static sounds into dynamic motion. The envelope follower can monitor the audio input, the sidechain input, a dedicated automatable parameter, or a MIDI CC message. You can adjust the modulation depth for each controlled parameter, precisely controlling how the envelope affects them. To provide a wide variety of textures and timbres, the plugin offers several models. The noise models introduce noisy artifacts, while the sine and triangle models enhance harmonic and tonal richness reminiscent of FM synthesis or RM modulation. The final models allow the use of either the internal or external audio signal (sidechain) as a modulator to affect your carrier signal, offering an interesting method to subtly blend the characteristics of one sound with another. Another standout feature of FAC Fizzica is the sideband control, which adjusts the balance between the processed signal and the isolated sidebands generated by the audio rate modulation. At maximum, only the sidebands are audible! Additionally, a built-in low-pass filter refines the tonal color of the digital textures. The workflow is optimized for simplicity and intuitiveness, featuring a central XY control pad for precise control, accompanied by a detailed visual representation of the envelope signal and all the modulations. Additionally, a spectrum viewer displays the audio output, providing clear visual feedback as you craft your audio to perfection. The plugin comes with two extensions, both audio effects, but the second one also supports MIDI input to control the main frequency and the filter cutoff with MIDI notes, as well as the envelope follower with MIDI CC messages. This is an AUv3 Effect and requires a compatible host to work The documentation is available at fredantoncorvest.com/FAC_Fizzica.html

Verdict
The clearest difference is in-app purchases: WaveFolder at none against FAC Fizzica's 3. WaveFolder also leads on price ($4.99 vs $9.99) and update cadence (every 3 months vs every 7 months). FAC Fizzica's advantage is rating (5.0 vs 4.6) and review sentiment (100% vs 75%). On ratings volume, ads, monetization model and device support there is nothing between them.
