In 2001 I bought a stand alone CD recorder to transfer my vinyl collection.
I am now in the process of ripping the resultant CDs and I thought this
might be a good time to correct some of my early recording mistakes - the
most common being that I forgot to manually increment track numbers.

Is it possible to split a single WMA track into the original component
tracks and, if so, how do I proceed?

An answer will be much appreciated even if it is negative.
