Since an All In One can rip and encode, this page is dedicated to pure encoders; that is, programs that take in an uncompressed sound format (usually WAV) and turn it into a compressed format (MP3, WMA, VQF, AAC). In addition, encoders that can serve as external encoders for All In Ones (in plugin fashion) will be pointed out as such.  Rippers are lower in the page as they are of even less importance than encoders, with today's overabundance of cheap and fast All In Ones.
