Accurate down low
RUBY processes every band in double precision, validates low-shelf gain down to 10 Hz, and keeps low-cut zeros fixed at DC. With a settled curve, its linear path creates no new harmonics to fold back as nonlinear aliasing
RUBY is a zero-latency equalizer built around a rigorously validated linear signal path—bit-exact when idle, harmonically clean under gain, and designed to keep its intended response accurate into the top octave.
Measured transparency, analog-prototype response accuracy, smooth transitions, and stereo-path integrity
RUBY processes every band in double precision, validates low-shelf gain down to 10 Hz, and keeps low-cut zeros fixed at DC. With a settled curve, its linear path creates no new harmonics to fold back as nonlinear aliasing
During validation, harmonic products remained below −120 dB even with an 18 dB bell boost, preserving the source instead of adding unintended saturation
Matched-Z filter designs follow their analog prototypes into the top octave, avoiding the high-frequency cramping of a naive digital transform
Center gain and key response behavior are checked from 44.1 to 192 kHz, so the same move remains predictable as the session format changes
Gain, bypass, band enable, shape, slope, and placement transitions are smoothed or crossfaded to avoid zipper noise and abrupt clicks
Correlated and anti-phase tests verify Left, Right, Mid, and Side routing, so a targeted change stays on the component you selected
The logarithmic graph keeps the composite response, selected band, and pre-EQ and post-EQ spectra in one clear view, so a visual edit always remains connected to what you hear.
Move from gentle shelves to surgical bells, notches, band passes, and continuously variable 12 to 48 dB/octave cuts across 20 Hz to 20 kHz
Read the source and processed spectra together while graph views keep Stereo, Left/Right, and Mid/Side decisions legible
Smooth parameter transitions, click-free bypass, output trim, undo, redo, reset, and A/B make every decision easy to challenge
Stable host parameters preserve all eight bands, automation identities, A/B states, and complete plug-in state with the session
