Trace smoothing varies

[Steviewunda]

Hi - as can be seen in this image the graphical representation of the trace varies even with the same smoothing applied. In this case all had Var smoothing, but the blue trace from the same location is much more jagged. Is there anything I can do to prevent this? These measurements were made using ASIO4all, Umik-1, sub only
Cheers

It doesn't appear to happen using Java - should I just use Java?

Something badly wrong with that blue trace, certainly. Looks like the result of feedback, e.g. from having "Listen to this device" selected in the Windows audio properties for the UMIK, but would be strange for that to change from one measurement to the next. Perhaps there were dropout problems. If you an access the channels you need with the Java drivers then nothing wrong with using those.

Haven't got "Listen to this device" selected in the Windows audio properties for the UMIK, and get this sometimes when changing ASIO properties in the Preferences dialogue -

I've had no more problems after enabling 'Allow pull mode (WaveERT) in the ASIO panel for the NVidia High Definition Audio device. Are there any drawbacks to this?

Not a setting I've seen mentioned previously, but good to know it seems to be helping. Might be useful for others in future.

The latest build is V5.20 RC6, by the way.
