Best audio format??

Best quality: - low bitrates (under 100 kbps): ogg and aac. These are better than wma and mp3pro. - medium bitrates (100 to 160): ogg and aac. - high bitrates (160 and above): mpc is generally thought to be best here, especially if your ears are more sensitive to time-based quality issues. Ogg is quite close in quality on the vast majority of clips, and may be better if your ears are more sensitive to tonal quality issues than to time-based issues. Ogg could surpass mpc in quality in the near future, although that isn't certain. AAC is also generally quite good up here, although its strength is at lower bitrates. Others: mp3pro is specifically optimized for low bitratres and streaming audio. Microsoft's wma isn't bad, but isn't as good as ogg or aac, and isn't that much better than mp3 at 128 and 160 kbps. Mp3 is standard, but overall the poorest sound quality for a given bitrate and filesize. Best hardware support: mp3, because it's the standard and has been around for so long. Microsoft's wma has some hardware support because Microsoft is pushing it. Ogg looks to be moving forward in getting hardware support. Open source: ogg is the only patent-free codec. Mp3 and mpc generally have no limitations on their useage. AAC is patent-encumbered, although Psytel is allowing individuals to have free usage of their encoder. WMA is heavily protected, although you can choose to encode in without "digital rights management" so that you are able to pass files around between people. My picks: ogg, and maybe some mpc at high bitrates. But I don't do any file exchanging and don't need hardware support (though I am counting on ogg's having hardware support in the future).
