Looks like it's running fine for me

Edit:
Checking option -ds
Running dsdplus.exe -o0 -O NUL -fa -dsXXX ? 1R-DSDPlus-Raw-Input_2023-04-11@092238.wav
best value of 58034 with -ds66
Checking option -dd
Running dsdplus.exe -o0 -O NUL -fa -ds66 -ddXXX ? 1R-DSDPlus-Raw-Input_2023-04-11@092238.wav
best value of 58034 with -dd4
Checking option -dv
Running dsdplus.exe -o0 -O NUL -fa -ds66 -dd4 -dvXXX ? 1R-DSDPlus-Raw-Input_2023-04-11@092238.wav
best value of 58034 with -dv18

+------ RESULTS -----+
Switches you want to use :
-ds66 -dd4 -dv18

0.1.2 DSDtune and latest fastlane release

You do realize that if you have a reasonable signal (20 db SNR or higher), there is absolutely no need for DSDTune. In many cases you can even have lower than 20 db SNR and still get a great decode. If you aren't getting a good decode, you need to explore why -- too much gain, too little gain, interference, wrong settings in FMP* / DSDPlus, SDR#, SDRUno, etc.

DSDtune hasn't even been updated in 6+ years.

I'm not saying it's necessary, but there's plenty of situations where a great SNR is not initially available. A mobile platform performing discovery for signals of interest coming to mind.

That's probably true when using a SDR dongles digital output. But using a direct discriminator tap from a receiver needs totally different values to be used. I need to have totally different settings for an Icom R2500 packet data output and for a Whistler TRX IF output or any other scanners earphone output. DSDtune is a must have program when not using a SDR dongle.
