WSTD FLDR
Key Features
- Wave folding distortion that inverts the signal at its peaks for unique harmonic generation unlike standard clipping or saturation
- Built-in RMS-tracking limiter that automatically tames output levels to prevent unexpected volume spikes
- Single-knob folding control with wet/dry mix for fast, intuitive sound shaping
- Open-source under GPL-3.0 with full source code on GitHub, completely DRM-free
- Native Linux support alongside Windows and macOS, covering all major production platforms
- Available in VST, VST3, AU, CLAP, and LV2 formats for maximum DAW compatibility
- Lightweight CPU footprint built on the Heavy Compiler Collection for efficient real-time processing
Description
WSTD FLDR is a wave folding distortion plugin from Wasted Audio that takes incoming audio and folds the waveform back on itself, generating rich harmonic content that ranges from subtle warmth to complete sonic destruction. Unlike standard clipping or saturation, wave folding inverts the signal at its peaks, producing a distinctive metallic, bell-like overtone character that is difficult to replicate with other distortion types.
The plugin keeps things deliberately minimal with a single main control for the folding amount and a wet/dry mix knob. An integrated RMS-tracking limiter automatically compensates for the extreme level boosts that wave folding can produce, keeping the output signal manageable without requiring manual gain staging after the effect.
Wave folding works particularly well on simple waveforms like sine waves and clean bass tones, where the harmonics generated are more musical and predictable. On complex signals like drum buses or full mixes, pushing the fold amount creates aggressive, aliased textures that are useful for sound design and experimental production.
WSTD FLDR is part of Wasted Audio's open-source plugin family, which also includes WSTD CRSHR (bit crusher), WSTD SMTHR (soft-clipping overdrive), and WSTD MANGLR (a paid modular distortion combining all three). The entire range is built on the Heavy Compiler Collection, transforming Pure Data patches into compiled C++ plugins.
The plugin ships as a native 64-bit binary for Windows, macOS, and Linux, supporting VST, VST3, AU, CLAP, and LV2 formats. It is completely DRM-free and released under the GPL-3.0 open-source license, so the full source code is available on GitHub for anyone who wants to inspect or modify it.

Tips
- Experiment with the wave folding amount to find the sweet spot for your track.
- Use the automated limiter to avoid clipping and maintain a clean signal.
- Combine WSTD FLDR with other distortion plugins for more complex sound design.
- Apply the plugin to different elements like basslines, synths, and drums to explore its versatility.
- Automate the wave folding amount for dynamic changes throughout your track.
Frequently Asked Questions
What is wave folding and how does it differ from other distortion types?
Wave folding is a type of waveshaping where the signal is folded back on itself at its peaks rather than being clipped flat. This creates a series of harmonic overtones with a distinctive metallic, bell-like character that you cannot achieve with standard saturation, overdrive, or bit crushing. The effect is most musical on simple waveforms like sine or triangle waves.
How does the built-in limiter work in WSTD FLDR?
The integrated limiter tracks the RMS level of your input signal and automatically adjusts the output to stay within that range. This prevents the extreme volume spikes that wave folding can produce, so you can push the fold amount without blowing out your monitors or downstream processing.
What is the relationship between WSTD FLDR and WSTD MANGLR?
WSTD FLDR is the standalone wave folder from Wasted Audio's distortion lineup. WSTD MANGLR is a paid modular distortion plugin that combines FLDR with CRSHR (bit crusher) and SMTHR (overdrive) in a single interface, letting you reorder the three distortion stages for more complex sound mangling.
Does WSTD FLDR work natively on Linux?
Yes, WSTD FLDR provides native Linux binaries in VST, VST3, CLAP, and LV2 formats. It runs in Linux DAWs like Ardour, Bitwig Studio, and REAPER as a compiled native plugin, not through a compatibility layer like Wine.
