How to calibrate your soundcard

If you ever experience warbles and/or pops when OtsAV is playing you may need to calibrate the Audio Output device.

Note: The Audio Output Device calibration settings only applies to true WDM drivers.

How to calibrate the "ON-AIR" output device

The idea is to lower latency, but without getting any cracks and pops. Position the slider after (to the right of) the region that causes the cracks and pops. Since this function is circular in how it works internally, the optimum position may actually be near the left of the slider (if the region of cracks and pops is to the far right).

Be sure to test your chosen setting under heavy system load, as some positions may seem fine until your system is loaded. Leaving a space of about 20 percentage points between the end of the region of cracks and pops and the position of the slider is usually optimum.

Tip: If your soundcard drivers appears in the Output Device list as Legacy drivers then you will normally be better off using legacy rather than the WDM.

Note: If you still experience warbles and/or pops you may be best to use the Compat mode driver selection. For instructions on how to set up your soundcard main channel click here.

Tip: OtsAV users should make use of ASIO drivers where possible.
