Encoding to either ogg or mp3 is lossy, but when converting back to wav the information in the mp3 or ogg audio should be retained completely. James is right when reminding me that going from ogg to mp3 incurs two opportunities of loss though, one from wav to ogg, and then another from ogg to mp3. Hence, when I converted ogg to mp3, I set the mp3 encoder to nearly cd audio quality to reduce that second loss. It still sounded crisp when played back. jack
