ANova Posted October 21, 2003 Share Posted October 21, 2003 The bitrate isn't what matters, since they all are capable of producing high quality. What matters is which format has the best size for the best sound. So which is it. MP3, AAC, MP4, WMA or OGG. Link to comment Share on other sites More sharing options...

velocity3k Posted October 21, 2003 Share Posted October 21, 2003 AC3 is multi channel AAC in a different container used in DVDs hmm, are you sure? :/ AC3 is a multi channel format, you probably know it better as Dolby Digital. It is usually 6 mono wavs joined together. The compression is amazing and it is mainly used on DVD's, for an average length movie, the AC3 track will be around 500mb.

123_kid Posted October 22, 2003 Share Posted October 22, 2003 MP3 could have up to 6 channels.-btw- usw mp3pro ;) Actually, there isn't a single implementation of multi-channel mp3's. link Link to comment Share on other sites More sharing options...
eppisode3 Posted October 22, 2003 Share Posted October 22, 2003 Yeah, ATRAC is pretty good. I just got a NetWalkman and it uses ATRAC for the compression. The software gives an option of 66, 105, & 132 bit rate. Using a 128MB MagicGate memory card and 105 bitrate, I can fit about 2 CDs of 15 songs each. Using 66 bitrate I can get about 4 CDs, and I have yet to notice an extreme amount of quality loss using the NetWalkman. All of my MP3s are 192 bitrate, btw. But to me, I notice more of an audio quality loss if I listen to 192 MP3 and then 128 MP3, than if I hear 192 MP3 then 66 ATRAC. Well, anyway, that's my input. I haven't messed with AAC, WMA, or anything else. Someday... Link to comment Share on other sites More sharing options...

Glowstick Posted October 22, 2003 Share Posted October 22, 2003 SO MUCH BULL**** IN HERE!!!! AAC isnt MP4 with ID3 AC3 isnt multichannel AAC, it's a frickin' different format MP3 doesnt support 6 channels, hacks are non-compliant bitstreams MP4 isnt a MS version of MPEG MP4 is a damn container format, AAC is the audio bitstream format AAC is damn old already, dates go back to 1996 and earlier. Some very few people might remember the Astrid Quartex compile of the ISO sources. Do you know when I used that one? 1998! .MP4 = Generic extension for MP4 files .M4A = MP4 container with only audio .M4V = MP4 container with just video .M4P = Apple DRM extension AAC LC = Low complexity version for low resource appliances AAC Main = LC with additional features like adaptive backward prediction AAC SSR = Forgot, something with samplerates, noone uses it AAC LD = Low delay version, for realtime applications AAC HE = High efficiency version, uses SBR Link to comment Share on other sites More sharing options...
