RESO

The deal

$49.50 at Plugin Alliance (down from $66.00).

What it is

RESO is a dynamic resonance suppressor from Mastering The Mix designed to tame the sharp, fatiguing bite that broad EQ can't fix. It analyzes your audio to identify problem resonant frequencies and applies targeted, dynamic reduction -- not static broad cuts. It works on individual sources like vocals, cymbals, and guitars, as well as full mixes.

Who it's for

Mix engineers and producers who deal with harshness and resonance issues in vocals, cymbals, synths, or guitars, and want surgical, transparent correction that doesn't dull the source.

Key features

• Calculate Targets automatically analyzes your audio to find resonant frequencies and places suggested reduction nodes with recommended levels
• Transparent suppression preserves transients and phase, keeping detail and energy intact without over-processing
• Frequency Sweep mode lets you manually hunt resonances by ear to fine-tune targets
• Supports AU, VST3, and AAX on Mac and Windows, with Apple Silicon native support
