Although it would be nice, I doubt anyone will be using USAC for ripping this year
 Interesting that opening the ALAC source code doesn't seem to have influenced its popularity. Chris -------------------- If I don't reply to your reply, it means I agree with you.

Can you give a rough evaluation already how far the improvements will go, e.g how good the codec will compete with AAC around 96 or 128 kbps in terms of sound quality? |

Can you give a rough evaluation already how far the improvements will go, e.g how good the codec will compete with AAC around 96 or 128 kbps in terms of sound quality? Assuming carefully tuned encoders, at 128 kbps or so, USAC w/o SBR will give about the same average quality as AAC-LC. My guess is that some killer items will sound a bit better (~ 5 MUSHRA points), and none will sound worse with USAC (guaranteed since USAC transform coding is very similar to AAC).
