(1) For audio replay (音頻播放), there is a new freeware foobar2000 available now with a lot of discussions around it. The sound quality of this audio player is definitely the first rate (arguably the best) and the user interface simple and effective. It supports most major audio formats (much more than most of us non-professionals would ever need).
(2) For audio format conversion (音頻轉換): LAME is the tool that should always be used for converting wav to mp3, because it is the best one. Hydrogenaudio Forum is the place to go to learn about conversions to mp3. LAME is free and can be used together with BeSweet GUI (also freeware).
