Compared to 3.97a5, cbr/abr modes are adjusted. Vbr modes are not yet changed compared to pevious alpha.

Results from 3.97a5:

edit: the former X10 mode is now remapped to X9 and used by default on abr/cbr.

CODE
VELVET (11.878s)
------

    CBR 128

-96.1 (2.4)  The bass drum is humping and the hi-hat (or snare? I dunno) sounds altered (stronger).
             I guess that's nothing new but I'm using velvet for the first time.
             The encoder struggles, there is one very short artefact that resembles a
             stream sync "bleep" error, with the bass drum attack at 10.5s

-97a6 (2.0)  Here are 3 instead of 1 noticeable "sync" errors (1.5s, 8.9s and 10.5s)

ABX 96.1 vs 97a6: effortless if you concentrate on 8.6-10.8s


    CBR 160

-96.1 (2.4)  I think the glitch a tad less pronounced than at 128k (ABX 13/16) after listening to 10.5s ~100 times :)
             Otherwise exactly like 128k.

-97a6 (2.1)  The 3 glitches are still there, but also a little less ugly than 128k when you listen often enough (7/8)

ABX 96.1 vs 97a6: effortless if you concentrate on 8.6-10.8s


    ABR 128

-96.1 135k (2.0)  I was surprised to find that ABR 128 is actually worse than CBR 128 here.
                  There are artefacts at 3.5 and 5.4s that are ABX'able from 96.1 CBR 128 (10/10)
                  The glitch at 10.5s is still there but got better over CBR 128.

-97a6 134k (2.4)  The glitches from 97a6 CBR 128 at 1.5 and 8.9s are gone, the one at 10.5s remains but got better.
                  The new problem of 96.1 ABR 128 at 3.6 and 5.4s is not present here.

ABX 96.1 vs 97a6:  8/8 because I concentrated on the 3.96.1 artefact at 3.5s that alpha6 does not have.
                   Sounds like a short jitter from a bad CD rip.


    ABR 160

-96.1 171k (3.0)  All singular glitches are gone, just the distinctive bass bumbling in the left channel remains :)

-97a6 167k (3.0)  ^same^...  Gah, the rumbling sounds like 2 huge rocks scraping together. rrrt brrrt rrrt brrrt...

ABX 96.1 vs 97a6: not possible


    V4 (medium)

-96.1 168k (4.0)  Hmmmm..  Very minor problem with the base drum. Oh well... :) (ABX 18/24 vs original)
                  Also, the hi-hats? seem still too crisp. but it'S barely noticeable. (8/10)                
                  This is way better than ABR 160, at 3kbit less bitrate.
                 

-97a6 167k (4.0)  Like 96.1, there is a gentle tone going together with the bass drum that gets distorted
                  slightly (8/8 vs original). And the hi-hat again too strong. (10/12)


ABX 96.1 vs 97a6: not possible


Conclusion: The glitches shouldn't be there in CBR (especially 160k); ABR is disappointing for both; V4 good.
