Bellweather Audio Core is an open-source C++ audio-core library from Bellweather Studios.

It includes framework-neutral DSP/core modules, RT-safety primitives, BS.1770 / EBU Tech 3341 metering tests, and Barometer, Bellweather's source-built JUCE reference plugin for loudness and true-peak metering.

The project is intended for inspection, reuse, and reference. Barometer is included to show how the reusable core can be exercised inside a real JUCE plugin without turning the repository into a plugin download channel.

Included:

• Apache-2.0 source release
• CMake library build
• BS.1770 / EBU Tech 3341 conformance tests
• RT-safe utility primitives
• Barometer source-built JUCE reference plugin

Not included:

• Prebuilt plugin binaries
• Installers
• Signing or notarization services
• Consumer plugin support channel

Build it yourself. This is a source release. To use Barometer as a plugin, build it from source via the included CMake presets. The repository is a code reference, not a binary distribution.
