I finally managed to buy a computer "beefy" enough to install the SONAR X3 Producer I bought last summer.  
 
I've been importing some .WAV files of old songs to start rebuilding them from scratch.  Is there any way I can have SONAR X3 analyze or process the resulting audio tracks to determine the tempo of the imported songs?
 
Thanks in advance for pointing me in the right direction.  Cheers!
