What effect are the sliders supposed to have?

[Alan Minnear]

I may have posted this question on the wrong page (see "A stunning improvement" on the opinion page). Here's my question -

On the latency compensation part with the two sliders for in/out, it doesn't seem to matter whether I set them to 0 or 1024. Why is this and what difference are they supposed to make. Sorry for the dumb question, but I would like to understand please.

These sliders have no impact whatsoever on audio processing but rather determine the additional latencies the driver will report to applications that are capable of full driver latency compensation, like e.g. Cubase.

A device may have certain components in the audio path that add to the overall latency but are unknown to ASIO4ALL, such as hardware FIFO buffers, additional processing stages in the WDM driver etc.

With the latency compensation sliders, these additional latencies can be specified. This is only important if you record audio with ASIO4ALL, in which case you want to make sure that a recorded audio click track is properly aligned with the original click track.
