RESO is a dynamic resonance suppressor from Mastering The Mix that identifies and reduces build-ups of energy at specific frequencies in a track or mix, and the plugin is distributed as VST3, AU and AAX.

What RESO does
Resonances that build up to excessive level can make music sound harsh or unpleasant and often mask other material. Applying broad reduction across the whole mix removes character from the audio, so RESO works on the specific frequencies that carry disproportionate energy relative to the rest of the mix and guides how much reduction is needed to resolve each one without overdoing it. The analysis display shows high peaks, a frequency sweep lets the user hear each candidate resonance, and Calculate Targets locates the most resonant frequencies automatically so they can be treated in turn.
Suppression is applied through nodes that are placed by clicking anywhere in the interface and positioned at the peak level where suppression should begin. Filters are described as mastering-grade and automatic Q optimization is provided for the most musical results. The developer positions the plugin for use on vocals, guitars, synths, drum buses and full mixes, and says any channel can be treated.
Key features
- Automatic resonance analysis. Calculate Targets scans the material and locates the most resonant frequencies, which can then be auditioned one at a time with the frequency sweep.
- Analysis display. The visual display shows peaks that sit disproportionately high relative to the mix, so candidate resonances can be seen before any reduction is set.
- Node-based suppression. Nodes are created by clicking in the interface and placed at the peak level where suppression should start, so each resonance gets its own treatment point.
- Automatic Q optimization. The developer lists automatic Q optimization as the setting that gives the most musical results when suppression is applied.
- Mastering-grade filters. The filters are described by the developer as mastering-grade and transparent, and they are used for the reduction at each node.
- Repack and crack builds. Repack, .rar and .iso crack builds circulate for RESO, and searches pair the name with keygen and serial key terms.
