Production grade. Built for all
Bellweather builds audio tools for real sessions, real deadlines, and engineers who need software they can trust.
Weather Station is our free desktop app for browsing, installing, and updating all Bellweather plugins.
Why we exist
Good enough is not a useful standard.
Bellweather came out of session work, not a feature roadmap. The tools are built to be used under pressure, measured honestly, and released only when they hold up in actual work. If it breaks the trust, it does not ship.
The Catalog
Tools that earn their place.
Barometer
Gain staging and loudness metering that stays out of the way
- Precision gain staging (-96 to +24 dB)
- Phase flip per channel with link
- Stereo width, balance, mono check, and channel solo
- LUFS metering (momentary, short-term, integrated)

Pressure
Flagship compressor built for control, tone, and repeatability
- Five analog-modeled engines (VCA, FET, Opto, Dynamics, VariMu)
- One knob to dial in the compression - threshold, ratio, attack, release, and knee, all mapped
- 40 parameters with full automation support
- Oversampling up to 8x for tracking, 32x for offline renders

Built to hold up. Tested to prove it.
Every release passes 1,000+ automated validations before it ships. The last thing you want to think about is whether it'll hold up in your session.

Why We Publish Research Notes In Public
Research Notes are not a marketing garnish. They are the place where product-level evidence, framework findings, and testing updates stay visible as the products evolve.
Testing
Pressure Mutation Testing Findings
Two early mutations revealed where the framework’s detection coverage could be stronger: DC offset passed undetected, and a gain spike slipped through artifact checks. Both findings led to immediate framework improvements.
