What does "measurement-fitted" mean?
We measured the target behaviour at dozens of parameter states and fitted our filter bank to reproduce the same frequency response. The result is a parallel IIR filter bank that matches the measured behaviour within 0.75 dB across all calibrated states.
Why do the bands boost more than they cut?
That asymmetry is faithful to the measured hardware behaviour. Each band boosts +15 to +19 dB at full, but only cuts −2 to −5 dB. These are broad musical lift bands, not surgical notch filters.
What is the Air Band?
A high-shelf boost at five selectable frequencies — 2.5K, 5K, 10K, 20K, and 40K. It adds presence, shimmer, and "air" without harshness. Start at 10K with Gain at 3–4 for most material.
What does Break mode do?
Break mode is an alternative voicing engine with its own colour and tilt character. Same five knobs, different musical response — warmer, more aggressive, less linear. Toggle it inline, no menu dive.
What happens when all five bands are set equal?
The frequency response is perfectly flat — pure gain, no tonal shift. This is a defining property of the complementary filter bank topology.
Does GlassBreaker EQ add latency?
Zero. Sample-by-sample IIR processing. No FFT, no convolution, no lookahead. Your DAW will report 0 samples of latency.
Can I use Air Band 40K at 48 kHz?
It works, but the frequency is clamped to 90% of Nyquist (~21.6 kHz at 48 kHz). For the full 40K effect, run your session at 88.2 kHz or higher.
How does the demo work?
Fully functional — every control active, no time limit. A 0.5-second noise burst plays every 60 seconds and will be printed in renders. No account required to download.
Why "GlassBreaker"?
A singer hitting the right frequency can shatter a glass. The Air Band does the same thing to a mix — it finds the resonant point that opens everything up. Glass is clarity. Breaker is the force behind it.
