I tried to use Audacity to record some bassline these days. Use my soundblaster Audigy2 as recording tool (sorry, no budget for firewire recording interface yet). I added a click-track, listen to it while recording. However, the result isn't match the click... thought it's my poor skill so I tried again, and again... finally I found that the wave I recorded doesn't match what I played. the click-track is 25.18 second, and my recording line is only 24.something. it's kinda "compressed" in time-length. Is that a problem of Audacity or sound card? Are there any solution besides buy a hardware interface?
