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.

HI,
foobar ABX plugin with replaygain, medicore Sony headphones were used

encoders:
3.96.1 and 3.97 alpha 6, --preset [cbr] xxx/medium --scale 1 --noreplaygain

First an oldie but goldie

CODE
FATBOY (5.00s)
------

    CBR 128

-96.1 (1.8)  The voice is badly distorted, as expected.
-97a6 (1.0)  Just abysmal... a6 introduces a horrible "bonus" artefact that sounds like
             a constant, warbling voice echo

ABX 3.96.1 vs alpha6: effortless


    CBR 160

-96.1 (1.8)  Sounds exactly like it's 128k brother. In fact I was unable to ABX between both.
-97a6 (1.0)  Again not ABX'able from the 128k alpha6 sample. Weird.

3.96.1 vs alpha6: effortless


    ABR 128

-96.1 164k (2.0)  A little better than 3.96.1 CBR (ABX 8/8 against CBR 160 with some effort)
-97a6 163k (1.2)  New voice echo artefact still there, a little less painful than CBR 160 (8/8)

3.96.1 vs alpha6: effortless

    ABR 160

-96.1 205k (2.0) Not ABX'able from ABR 128
-97a6 201k (1.5) Echo gets a little better if you listen closely (ABX 10/12 vs ABR 128)

3.96.1 vs alpha6: 8/8 easy


    V4 (medium)

-96.1 236k (4.0)  nice.
-97a6 233k (4.0)  yeah.

not ABX'able against each other

V4 vs. original was tricky first, but after some loops you start noticing a slight hiss in the voice


Conclusion: something went very wrong for Fatty in Alpha 6 (CBR/ABR). ABR poor despite healthy bitrate. V4 good.
