GlassBreaker EQ was designed from measured frequency-response data. We captured a defined calibration set across dozens of parameter states, extracted the frequency response at each one, and fitted a parallel filter bank to follow the same broad tonal shape.
The result is five broad, overlapping, boost-leaning bands that interact as a complementary filter bank. Boost one band and its neighbours respond. Set all five to the same value and the overall response stays flat apart from level change: gain without intentional tonal shift. That constraint is built into the topology.
Each band boosts far more than it cuts: +15 to +19 dB at full boost, only −2 to −5 dB at full cut. That asymmetry comes from the measured calibration set: these are broad tone-shaping bands, not surgical notch filters.
The Air section sits on top: a high-shelf boost at five selectable frequencies from 2.5 kHz to 40 kHz. At 10K it adds broad high-frequency "air" for vocals, acoustic instruments, and full mixes. At 2.5K it adds presence and forwardness. At 40K it reaches into ultra-high frequencies for sessions running at 88.2 kHz or higher.
Break mode is an alternative voicing engine with its own colour and tilt character, switchable inline. Same five knobs, different response: thicker, more aggressive, and less linear. One toggle, no menu dive.
GlassBreaker EQ reports 0 samples of latency. It uses sample-by-sample IIR processing, with no FFT, no convolution, and no lookahead. Calibration is within ≤0.75 dB across the measured calibration states.
GlassBreaker EQ is offline-first. No internet connection required for activation or use. The plugin sends no telemetry, performs no phone-home checks, and does not require an online account inside the DAW.
All current and future plugins in that bundle. Updates included for life. Prices rise as more plugins are added.

Presence and clarity. 2.5K for dense mixes that need cut-through without brittleness. 5K for vocal presence and string brightness.
The default. Broad high-frequency "air" for opening up source material — the recommended starting point for most work.
Subtle top-end sparkle at 20K. Ultra-high at 40K — only meaningful at 88.2 kHz or higher sample rates.
Sub, 40 Hz, 160 Hz, 650 Hz, and 2.5 kHz - five broad bands, one knob each. Lift, trim, and move on. No frequency hunting, no Q tweaking, no surgical work.
A separate high-shelf section with selectable points at 2.5, 5, 10, 20, and 40 kHz. Add presence, shine, or open top end without dragging in a second EQ.
A toggle that swaps the band voicing for a denser, more coloured character. Same bands, same controls, stronger attitude. For the moments when clean EQ is not the answer.
Switch between Stereo, Left/Right, and Mid/Side operation from one control. Internal Mid/Side encode/decode and Lane Link let you move quickly between classic stereo polish, independent dual-lane work, and width-aware tone shaping.
