[quote name='Static']Well... how about HD sound then?[/QUOTE]
Umm, Dolby Digital is not considered "HD sound," it's compressed audio even though it's 5.1 each channel is lower quality than 5.1 in a theater. As far as I know on ALL Xbox 360 games Dolby Digital is the best quality audio setting you can turn on. The Xbox 360's audio capabilities are limited to compressed audio, it's not built for uncompressed audio, even with the HD DVD add-on playing a HD DVD movie with Dolby True HD it only put out a Dolby Digital or DTS signal (I forget which), so basically it's limited to DVD Video quality audio. The Playstation 3 is a different story, I don't play games on my PS3 but Blu-ray Disc movies on the PS3 can have uncompressed sound in three different ways: PCM, Dolby True HD, and DTS HD Master Audio. I don't know if any games have audio settings that you can turn on any of the three ways to get uncompressed sound, so if any PS3ers care enough to post they can say for sure if it's capable or not. So yeah I don't know if DJ Hero on the PS3 is made for "HD Sound," But the Wii and Xbox 360 are incapable of "HD Sound" for sure.
