Product Name: RESO Product Type: Audio plugin Brand: Mastering The Mix Primary Category: Dynamic resonance suppressor Primary Use: Identifying and reducing harsh resonances in audio Best For: Vocals, acoustic guitars, drums, synths, full mixes Formats: VST3, AU, AAX Platforms: macOS and Windows License: 2 license seats as standard Description RESO is a dynamic resonance suppressor plugin from Mastering The Mix that helps producers identify and reduce harsh, ringing, or brittle resonances in audio. It applies dynamic cuts that act only when the resonance flares up, so the rest of the sound stays more natural. What RESO Does RESO scans the input signal for resonant frequencies and presents them visually. The user can apply dynamic cuts on detected resonances, with the cuts triggered by the resonance itself rather than acting as static EQ. How To Use RESO Insert RESO on the track that needs treatment. Let RESO scan the signal and display detected resonances. Apply dynamic cuts on the resonances that are causing problems. Adjust sensitivity and threshold to taste. Use delta monitoring to hear what RESO is removing. Key Features Automatic detection of resonant frequencies with visual feedback Dynamic, signal-triggered cuts Multiple resonance bands with independent control Mid/Side processing Delta monitoring to hear what RESO is removing Clean filter design suitable for mastering use Common Use Cases Reducing harsh vocal resonance, nasal honk, and box resonance Controlling boxiness in acoustic guitar recordings Taming ringing toms, harsh cymbals, and snare ping Smoothing fizzy or piercing synth and electric guitar frequencies Cleaning up mastering-stage resonances FAQ What is RESO? RESO is a dynamic resonance suppressor that detects resonant frequencies and applies signal-triggered cuts only when those resonances are active. Can RESO be used as a de-esser? RESO can help with harsh upper-frequency resonances, but a dedicated de-esser may still be better for cl
