# SPL Lab Web: NEXT LAB measurement client and device protocol

> SPL Lab Web replaces the measurement functions of the NEXT LAB bass meter's Windows software with a Node service, browser interface and Electron app. Its device protocol document draws on Ghidra decompilation, configuration files and live tests; the client reads USB serial data, computes measurements and exposes an HTTP/SSE API.
