It's just a box connected via USB , you don't need an external sound card to measure ZRLC,
You can use VisualAnalyser or an other program, A link to the dedicated to the software

Under Linux no drivers is required Under Windows you can find in the folder "Drivers_windows" all you need to run this box properly

Questions
How big is the ZRLC CMS PCB?
It measures 92.8 × 39.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ZRLC CMS use?
35 parts, built around the ICL7660N, LM386 and LME49721MA. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ZRLC CMS KiCad files?
From the Totof34/ZRLC_USB repository on GitHub, at the commit this page was made from: the board is source_kicad/ZRLC_CMS/ZRLC_CMS.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ZRLC CMS design in my own project?
Its repository states no licence, so its author keeps all rights: ask Totof34 before reusing the design.
