How do I get an acceptable performance and latency on the MS Windows platform?

Up to Table of Contents

I've Installed Pure Data (or Pd-extended) on Windows and I have to set the buffer (delay) to more than 100ms to avoid audio drop outs (crackling). What can I do to achieve a proper latency in Pd on Microsoft Windows?

Make sure your Windows system is set up for Audio. Make sure the overall system performance is OK, install updated ASIO drivers for your soundcard or the "ASIO4All Drivers":http://www.asio4all.com/ when no ASIO is available from the manufacturer. There is also an "ASIO driver for WDM kernel-streaming compliant soundcards":http://www.asio2ks.de/

USB and persitency

If you have the problem that you can only plug in your external sound card to one specific USB port you might want to make the COM port assignment of the system permanent to this device. Here is How: goto control panel -> device manager -> com ports -> properties -> port settings -> advanced -> comport number there you can permanently set the comport number for that device.
