But even that is less latency that I used to get with my old PCI soundcard (EgoSys Waveterminal 24/96) on WinXP. This was an expensive professional soundcard when I bought it six years ago. It's just my experience, but with gnu/Linux, jack and the alsa-usb-audio driver you get far lower latencies than when using other operating systems. Ciao, c. www.cesaremarilungo.com
