JS Inflator
Key Features
- Waveshaping engine replicates the Sonnox Oxford Inflator curve, producing near-identical null-test results across all parameter settings
- Double-precision 64-bit internal processing with double-precision I/O when supported by the host DAW
- Oversampling up to 8x with selectable minimum-phase or linear-phase FIR resampling using SSE2/NEON optimization
- Two switchable GUI skins integrated into a single plugin, including an alternative interface by Twarch
- Band Split mode for applying inflation to separate frequency ranges independently
- Soft Clip function prevents output overages, mirroring the behavior of the original Oxford Inflator's clip stage
- Native Apple Silicon support on macOS alongside Intel, with tested compatibility in Cubase, Ableton Live, Logic Pro, Cakewalk, and Bitwig
Description
JS Inflator is an open-source waveshaper plugin by Kiriki Liszt that replicates the behavior of the Sonnox Oxford Inflator. It runs in double-precision 64-bit internal processing and comes in two GUI skins, including an alternative design by Twarch.
The plugin uses the same waveshaping curves as the original Oxford Inflator, producing results that null-test to near-identical levels. Controls include Input and Output gain with VU metering, a Curve knob for adjusting the saturation intensity, an Effect blend knob, Clip for soft clipping, and Bypass.
One area where JS Inflator goes beyond the original is oversampling, offering up to 8x with both minimum-phase and linear-phase options built on a custom FIR resampler with SSE2 optimization. A Band Split mode is also included, though the original Inflator's multiband processing is not replicated.
Users on Reddit and KVR consistently praise JS Inflator for delivering the same loudness-boosting, dynamic-preserving character as the Oxford Inflator without the iLok requirement. Several report using it on mix buses and master chains as a final stage before the limiter.
JS Inflator is available for Windows 10 or later (64-bit) and macOS 10.13 or later with native Apple Silicon support. It ships in VST3 and Audio Units formats.

Frequently Asked Questions
How does JS Inflator compare to the Sonnox Oxford Inflator?
JS Inflator uses the same waveshaping curves as the original, and users report it null-tests to near-identical levels on most settings. One advantage it has over the original is oversampling up to 8x with linear-phase mode, which the Oxford Inflator does not offer.
Does JS Inflator require iLok?
No. JS Inflator is open-source software distributed under the GPLv3 license. There is no copy protection, iLok requirement, or authorization step -- just download and install.
What is the difference between the Curve and Effect controls?
The Curve knob adjusts the shape of the waveshaping distortion, with higher values applying more saturation. The Effect knob acts as a wet/dry blend, controlling how much of the processed signal is mixed back into the output.
Does JS Inflator support multiband processing like the original?
JS Inflator includes a Band Split mode that separates the signal into frequency bands for independent processing. However, it does not fully replicate the original Oxford Inflator's multiband processing implementation.
