Tone Projects Kelvin Tone Shaper: A dual-stage saturation and passive EQ plug-in
Developer Tone Projects, known for its well-received Unisum mastering compressor plug-in, has a new release. Kelvin is a dual-stage saturation and push/pull EQ plug-in based on an improved version of the “Hygge” saturation mode from Unisum.
Tone Projects Kelvin Tone Shaper
Through its fairly simple interface, Kelvin lets you choose from 8 transformer, tube, and diode circuits to add harmonic coloration and warm saturation. Each of the two saturation stages can have a different algorithm applied with separate gain adjustments. You can also dial in frequency specific distortion and analog-style tone sculpting from the EQ section. Each of the three bands (Low, Mid, High) lets you choose the filter shape and the amount of tonal balance applied pre and post saturation. This way, you can be very meticulous with the plug-in’s application.
The Low and High bands are based on a passive Pultec-style EQ, though simultaneous boost and cut is not an option. The rest of the controls include:
- Spread (create width through subtle harmonic variances)
- Defuzz (reduce mid-high frequency saturation and clean up artifacts)
- Clip (shave off peaks or add a third crush stage), Output trim
- Wet/Dry Mix knob
Sound quality is further ensured by high fidelity oversampling with separate setting for offline rendering quality. Other helpful features include A/B preset switching and an integrated reference level system which automatically adjusts input level to match loaded presets.
I haven’t played with the trial version yet, but initial feedback is very positive. If you liked Unisum, chances are you’ll feel the same for Kelvin Tone Shaper.
Price and availability
Kelvin Tone Shaper is available in 64-bit VST3, AU, and AAX plug-in formats for Mac (Intel/ARM) and Windows computers. It’s being sold at an introductory USD 74, down from USD 99 regular. The offer is valid until July 9.
