Vbr modes are not yet changed compared to pevious alpha. Results from 3.97a5: http://www.hydrogenaudio.org/forums/index....showtopic=30547 edit: the former X10 mode is now remapped to X9 and used by default on abr/cbr.

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. Hmm ouch
