RESO

RESO by Mastering The Mix is a dynamic resonance suppressor for taming harsh frequency buildups without stripping away the character of your tracks. Rather than applying broad cuts, it targets problem frequencies and reduces them dynamically, helping preserve body and transient punch. Use it to smooth an edgy vocal, control piercing synth tones, tidy percussion, or address resonances across a bus or full mix.

The visual display highlights excess energy, while Frequency Sweep lets you listen for troublesome spots. Calculate Targets identifies resonant frequencies and suggests reduction targets, giving you a practical starting point. Click to create nodes, set the level where suppression begins, and adjust Q as needed. Automatic Q optimization and transparent filters support subtle, musical processing. RESO suits home producers and mix engineers who want a guided approach to resonance control, from individual tracks through mastering.
