Signal receive tming?

I just noticed that my 6700 produces audio and amplitude signal on waterfall about 1/2 second behind the analog receiver here. Is this normal for an SDR receiver??

    Hi Bob, latency is normal for SDR radios. The long latency you are experiencing is more likely in your network. Are you connected to the Flex with WiFi or is your computer directly wired to your network? Are you connected remotely using SmartLink?

    Windows audio also generates latency, as much as a couple hundred milliseconds.

    Good point Ted! Bob, are you using speakers or headphones plugged into the Flex, or audio from the PC? If from the PC, that could account for most of it.

    Latency is also affected by filter settings. Perhaps start by checking the filter settings for low latency settings.

    I can tell you non of the other SDR´s on the market have noticeable delays with Windows (Hermes, SunSDR, Zeus).

    Flexradio with MAC-Software does have minimal delay.

    Flexradio with Windows (also Maestro) has 0.5 to 1s delay, thats way too much and NOT normal!

    The support knows the problem but has no idea how to implement Windows low latency audio path since 3 years.

    I haven't noticed any delay with my iPad. Nor do I notice any with Windows as long as the rig and the computer are plugged into the same network switch.

    No lag only if I plug headphones/mic directly into my 6600 Flex. @ka9ees what model do you have?
