A typical sound card for recording is 96K or better. So if you have a really good sound card you can improve things. I have a firewire MOTU sound card that's 96K
96K what? I have a sound card that came integral to the laptop. I'll be trying that. It worked real well with just two handclaps using the Audacity freeware and the built in mic. I have a better mic to use for the testing. I'm not trying to get .1fps accuracy. I'll be happy with 50fps.
