Hi MaTTeR, what's your fav. ? Vorbis or AAC :) ? i'm an AAC fan since i bought Philips' Expanium portable CD/MP3/AAC Player :D

Hi Dg, In terms of multi-channel performance I think AAC beats Vorbis easily for several known reasons. 2ch though...well I'm not so sold on AAC yet although I've done know "serious" tests yet. Man I wish I had one of those nice Philips boxes. Strange it doesn't support Vorbis though:confused:

well, i guess that Vorbis will beat AAC evantually. don't forget that MPC's developer, Frank Klemm, might contribute some work of his own to Vorbis. as for hardware support for Vorbis, i guess it's only a mAttEr of time ;)

yes.. this is a discussion about (sort of) modern audio codecs that implements lossy algorithms for audio compression. AAC was introduced on the specs of MPEG-2, just like mp3 was introduced on MPEG-1 specs. Vorbis.. well, you should know about it by now ;) MPC is a VERY good codec (also known as MpegPlus), based on mp2 specs with lots of improvements. MPC's encoder is closed-source. (juse like AacEnc, unlike Lame or OggEnc), so ppl finds it very nice that MPC's developer might take a part in Vorbis, as an open-source encoder. i believe Frank's chances to improve Vorbis' quality are pretty high.

Indeed that's great news to hear Frank will help the Vorbis efforts. I wonder how much money it would take for us to talk Nic into finishing the AAC DSF:D Anyone heard of an MPC DSF project yet?

It sounds great. And btw, which are de benefits of AAC about multi-channel? i thought ogg vorbis was good about that (at least the above graphic tells something about 255 channels - i don't know german, so maybe i'm missing something). It has to do with Tobia's Filters or with ogg vorbis specifications?
