Common-Radio™
Audio Driver
Introduction
The Common-Radio™ Audio Driver enables seamless integration between HAM radio applications — including SmartSDR, SDR-Control, FT-Control, TS-Control, and K4-Control — and external tools such as WSJT-X and fldigi or other third party software. Unlike the loopback drivers previously required for this purpose, Common-Radio™ Audio Driver is purpose-built for these applications, optimized for ultra-low latency and smooth, uninterrupted audio routing and seamless integration to the apps.
System requirements
macOS 26 or later is required. The driver is code-signed and notarized by Apple.
Installation

Note: A restart may be required after installation for the driver to appear in your system.
Updating the Driver
If the Radio app you are using requires a newer driver version, you will get prompted to update the driver. To update to a newer version, simply download and run the latest installer using the button above. It will automatically replace the previously installed version — no manual removal needed.
Uninstalling the Driver

Note: A restart may be required after uninstallation
