I'm recording with the "1 minute recorder" in windows and mixing the tracks with Sonic Factory's ACID DJ. When I play back my tracks, they are slower than when I recorded them. If I change the tempo, the drum track I used as a base changes too. How can I fix this problem?
Sounds like a sample rate issue. Make sure your record/playback settings for your sound card are 44.1KHz, as well make sure they are the same in the Sonic Foundry software.
Instead of using the windows recorder, try something decent like goldwave: www.goldwave.com
