Switchboard is a real-time orchestration layer that makes it easy to assemble C++ audio building blocks into complete audio graphs — without writing C++ yourself.
Many nodes wrap open-source and third-party libraries; the real work is the C++ audio engine that makes them work together and the bindings that let graphs run anywhere.
Switchboard abstracts the low-level requirements — real-time threading, CPU/GPU optimizations, sample-rate conversion, buffer management, and platform APIs like CoreAudio and AAudio.

Available at the enterprise tier with additional cost. Otherwise, support runs on a best-effort basis — a monthly subscription is the recommended way to address this concern.
