FLEX-5000 Users (and future FLEX-3000 users): We have received some questions recently about the driver buffer size setting and how it relates to the buffer size in the PowerSDR Setup Form -> Audio Tab. We thought we would clarify it here on the reflector so it might help others that had the same question.
The basic idea is to match the two settings at a reasonable size for your sample rate and system performance. A good starting place for the default sample rate of 96kHz is to use a buffer size of 2048 in both places (driver control panel and Audio Tab in PowerSDR Setup Form). If you make a change to the buffer size in the Audio Tab, you'll want to make the same change in the driver control panel. At no time should the Audio buffer size be smaller than the driver buffer size as this will cause audio distortion which sounds similar to RF. At some point we hope to enable this process to happen automatically and have requested such an interface from our chip vendor. Until then, we plan to add a pop up to remind you to setup the driver when changing the Audio buffer size. If you have further questions about the interactions of the buffers, there is an excellent section in the appendix of our Operating Manual that describes in more detail the interactions and ways to optimize for various operating preferences. Thanks for your time and enjoy your radio.
