Simply summing L and R signals will cancel low frequency rumble from the turntable.

And from the cutting lathe.

If the stereo recording has equal level in the two channels, simply summing them will do the job. You'll probably need to filter out infrasonic noise; a 3rd-order filter at 16Hz will do that. The scientific filters in Audition will do the job. Record in 24 bits (or 32 bits floating); after you've done everything you want to do to the signal, convert to a6 bits for burning a CD.

What's the content on the record you want to convert?
