I've been trying to use Audacity
 I changed the bit rat to 48 on 16 bit and it seemed to do good recording track 1 as a karaoke song and then track two as a vocal.
But when I record live music on track 1 and then add another track of additional instruments the timing gets further and further off as the song progresses.
I am running a Compaq , windows xp, 1gb ram , celeron 2.5ghz processor with on board ac97' sound with the most updated driver.
What should I do?
Thank you
