poor voice response time resolution (case 14820)
Our lab collected a large amount of word naming latencies using Direct RT 2012 and a headset microphone. The computers are newer Dell desktop units. Problem is there is a clear evidence +/- 30 ms buffering going on in the sampling. Any ideas how this could come about, its as if we were using 1980's equipment. See attached histogram.
The only thing I have come up with is perhaps my students have plugged the mic into the front of the PC, and perhaps that jack does not use the main sound card? Otherwise, I have no clue. Please help!

It turns out that the microphone was plugged into the back of the machine when the data was collected. The sound card hardware is just the default hardware that is included with the Dell machine. The config files you requested are attached.

The X axis of the histogram is pronunciation time, on a millisecond scale, observations start at 0 and range up to 1600 ms. The Y axis is the frequency with with each interval of pronunciation time was observed. The data are collapsed across about 40 participants, which is why there are such large frequency counts.
