Fast Lane includes dedicated tuner applications (like FMP24) that control your RTL-SDR dongle directly, bypassing the need for complicated virtual audio cable routing. RadioReference
Although DSD+ can operate in a basic mode via a virtual audio cable from any SDR app, the best performance is achieved by utilizing the native FMP24 or FMP programs included in the DSD+ suite. FMP24 acts as a dedicated receiver for RTL-SDR devices and communicates directly with DSD+ via a TCP link. This bypasses Windows audio mixer latency and eliminates potential interference from other system sounds. You can find detailed instructions for this setup in the DSDPlus/HowTo guide, which suggests launching FMP24-CC.bat for control channel monitoring and using arrow keys for fine frequency adjustment.
