How to mix same two songs with audacity?

I want to mix two of the same song by two different artists with audacity. I know how to mix them but the audios are off by like half a second. I've tried trimming them and starting them at different times but it's not working. Is there another thing on audacity that can get them to flow correctly? Thanks.|||"dew..." makes a good point, but there may be a way around that with a little work.

With spectrograms aligned one under the other, the rhythm or tempo can be noticed by the peaks and/or valleys; for the tract that's running slow, note the discrepancy, then highlight the entire slow track%26gt; Effect%26gt; Change Speed (or tempo)%26gt; modify the speed to match the noted discrepancy (default is 0, - makes it slower so move slider right)%26gt; OK (wait for the changes to become effective). This may take a bit of tweaking to have the audio behave like you want.

When finished, export the entire kaboodle to a folder of your choice, making sure to save the 'project' itself, as these would be the settings and so on for Audacity, (there are two things to 'save' in essence)...in case you need to come back and tweak it later.|||Unless the two artist are using the exact same musical track, the odds are that they are not going to be in perfect synch with each other. One may be slightly faster than the other in how they sing the song, or they may repeat different parts of the songs at different places. It is very very unlikely that two artist using different musical tracks will match each other. So even if you could get the first few notes to match perfectly, it is unlikely that they would stay in perfect synch.





If you really want to match the two, you are probably going have to go measure by measure through the music and slightly adjust one of the two tracks every three or four beats to keep it in synch with the other track. Major undertaking, and questionable as to how the final results will sound. It will probably make the music track in the adjusted track very "jumpy".





I am not aware of any way to use Audicity (or any other program like that) to get two different tracks like that to synch,
