iTunes' VBR mode is worse than its CBR mode.
As for FhG, MMJB could be an option if VBR is needed. Aren't both WMP's and MMJB's MP3 encoders based on FastEnc?
I think we are nitpicking regarding the title. I used the term "@ 128 kbps" because of the tradition. I can also call it "@ ca. 43 * Pi kbps".
So, for the encoder decision and settings, do you think some pre-tests are appropriate?
I find it hard to believe that 6 kbps difference between iTunes and LAME can make such a difference in quality.
And if iTunes VBR implementation is so good, why didn't it allocate more bits for hard parts like LAME did?
Jesus, that's a lot of pre-tests. I am thinking of another possibility... Only thing that comes into my mind would be running two tests: one with all encoders using CBR and one with all encoders using VBR. However, this is rather complicated. We would have to use the same samples, but then the factor tester could have an impact on the results (different testers or even moods = different results).
Ahhh, am I too late?? I wanted to suggest slipping a standard iTunes AAC @ 128 kbps as "pseudo-high" anchor. Might be interesting to see if you could say AAC really is "out of MP3's league" or if MP3 in general (...ok, Lame ) is a good contender. Ok, shut me up... (Hey! First post in many many months! Yay!)
Who is responsible for WMPs encoder?
As I mentioned above, the FHG Fastenc encoder forces simple stereo in VBR mode. So I suggest testing it in CBR (even if all other contenders are in VBR), because I'm sure it will perform better with CBR.
we won't know if CBR or VBR was better for certain encoders.
If you view the test as a study that should have some authorative value over which encoder is best and how they compare, a poll isn't very scientific.
... On the other side, didn't Fastenc joint-stereo suffer from another kind of bug (stereo collapse or something like that)?
And as far as I can remember, we didn't mail to Apple developers neither the Microsoft ones to see if we had to prefer CBR over VBR with iTunes AAC or WMAPro (last 130 kbps multiformat listening test).
