Deres Black Friday Deal 2026: $11.96, 60% off

Deres Black Friday pricing from W. A. Production is 60% off this resonance-reduction plugin, which brings it to $11.96 until Nov 29, 2026.

Deres is a de-resonance plugin built to find and soften the buildup that muddies a mix. It targets harsh overtones and hidden resonances, the kind that pile up when you layer synths or stack bass lines.

The maker says it works from the mathematics of sound harmonics rather than guessing at problem frequencies.

How does Deres find and reduce resonances?

The Listen button exaggerates the offending frequencies so you can hear them before you touch anything. Sweep the Find knob across 1 to 8 kHz until a muddy or harsh peak jumps out.

Then bring in the Reduce parameter to apply the processing. The Q value widens or narrows the band, so it catches more or less of the neighbouring frequencies.

Unlike a surgical EQ that works on one tight slice, Deres also processes the harmonics of the frequency you pick. The Octave knob pulls down those related components so the whole family of problem peaks is handled together.

Static mode cuts in a linear way. Dynamic mode only steps in when the resonance actually appears, which the maker describes as more musical processing.

What keeps the sound from going flat?

Cutting resonances can leave a signal a little dull, so Deres adds compensation tools:

• Tone: adjusts the tonal balance of supporting parts like pads and strings, using a convolution response and removing unnecessary frequencies
• Compensate: boosts the frequencies next to the cleared ones to offset any perceived darkness
• Excite: adds air after resonance removal to bring back presence and sparkle
• Mid/Side mode and low cut filtering

What else is in the plugin?

The interface is vector-based and resizable, with a live spectrum across the top showing what happens to the signal in real time. AB comparison with copy and paste lets you contrast two processing settings, and undo and redo step back through changes.

The factory presets run from subtle surgical correction to broad transformations, and they work as starting points for any type of audio. A full PDF manual and a tutorial video come with it.

The feature list:

• De-resonance processing with advanced harmonic detection
• Static and dynamic modes
• Compensation parameters
• Frequency spectrum monitoring
• AB comparison and undo/redo
• Resizable interface
• Responsive and CPU friendly, according to the maker

What are the system requirements?

On Windows you need Windows 8 or later, 64-bit only, with VST2, VST3 and AAX formats. On Mac it's macOS 10.10 or later, 64-bit only, with VST2, VST3, AAX and AU.

AAX works with Pro Tools 11 and higher only. If you're on Apple Silicon, the maker asks you to review the plugin's current compatibility status before buying.
