How can i compress WAV or MP3 files?

Audio cettes opened up a world of portability unimaginable in the days when LPs ruled the roost. Now, however, cette tapes have fallen by the wayside (or, in many cases, have been thrown to the wayside from moving vehicles), and, unlike LPs, they don’t look like making a comeback anytime soon. This poses a problem for those of us who would like to preserve important conversations or good songs that are currently stored on cettes, not only because audio cettes eventually deteriorate or get “eaten” by your tape player, but also because cette players are becoming increasingly rare. Fortunately, you can easily transfer audio from cettes to your computer, where it can be stored in formats such as WAV and MP3 or can be burned to CDs. In fact, $6 could get you everything you need.
