SMOOTH / plugin 01
dynamic resonance suppression that hears like you do.
find and tame harsh resonances across your mix. SMOOTH hears frequencies the way you do. one knob gets you 80% there. five knobs get you all the way.
50 papers. 5 knobs. $29.

SMOOTH v1.3.2 with refreshed visual identity, editable EQ values, and improved controls.
listen
hear the difference.
click play. each demo plays the original, then auto-switches to SMOOTH halfway through. click either box to toggle manually.
🎧 for best results, listen on headphones or studio monitors.

see what you're hearing.
SMOOTH processing a vocal track in real time. the spectral display shows resonances being detected and tamed across the frequency range.

features
what makes SMOOTH different.
psychoacoustic precision
40 frequency bands mapped to how you actually hear. not arbitrary frequency splits.
dual character modes
resonance mode for sustained harshness. transient mode for percussive spikes. switch or blend.
M/S routing
process mid and side independently. tame center-panned vocals without touching the stereo field.
spectral display
real-time visualization of what's being reduced. see the problem, see the solution.
specifications
the numbers.
system requirements
learn the science
understand what SMOOTH is doing.
free guides built from the same research behind the plugin. no paywalls, no courses to sell.
what is resonance
every signal chain has resonant frequencies. understanding them is the first step.
04how spectral processing works
FFT, frequency bins, magnitude and phase: the math behind SMOOTH.
05ERB scale and psychoacoustics
why SMOOTH uses 40 ERB bands instead of linear frequency bins.
