Is there a way to improve the audio quality of DSD Plus Fastlane when monitoring a P25 system?

Signals are good. The audio has a tinny sound to it. I always had that only with P25 anything else is fine. I wonder if there was a way to tune the decoder. P25 Ph1 and 2.

For best decoded audio quality ensure the SDR is "on" frequency and that you're not seeing frequent reports of "Errors" or "CRC's" in the DSDPlus Event Wndow/Logs.

Next expermint with -u<num> Unvoiced speech quality (1-64) [-u3] settings in your batch file that runs dsdplus.exe. I am gettng very acceptable IMBE audio with a setting of -u12 while using an Airspy Mini with DSDPlus Fastlane.

Its probably the implemented vocoder that sounds meh that you're talking about I hope they change it soon for improved voice quality
