Sometimes the VU Meters within the Editors or MultiRec module appear to be acting delayed; when one makes a recording, the LED Signal Levels react slower than the input signal.

This is due to the fact that the routing of an input signal is not always handled the same by different hardware manufacturers. There is unfortunately no standard interface to connect the signal level indicator of D.A.V.I.D. modules so that it will work consistently with every multimedia card.

The only solution to this would be to write a program for each and every soundcard on the market! Of course, because this isn't practical we can only suggest that one decrease the multimedia recording buffer to increase the reaction time of the indicators. However, be aware that there is a greater potential for audio dropouts when this buffer is reduced.

With MultiRec, the 2 decisive parameters that one might adjust to achieve the optimum balance between meter reaction time and dropout insurance are;

Section DBM\MultiRec
WaveInBufferSize=[default: 65536, possible value range: 1024 ... 524288]
WaveInBufferNb=[possible value range: 2 ... 64]

Actually, the point of the post is that there is no simple solution to the issue, there is only the compromise you can make on one side or the other; either delayed graphics or increase the potential for dropouts. If we could offer both latency-free meters as well as dripout insurance, we would have of course developed that..
Unfortunately this is an inherent limitation of the system and Microsoft's drivers. We are currently developing an ASIO driver capable audio engine that may improve this situation (keep an eye on the SIS News [Home] page)!
