Excellent. 
Great work from the LAME devs.
And thanks for the early heads-up skelly831.

Would I be correct in assuming that there is actually no difference in the encoder bewteen 3.97a12 and 3.97b1?

I see no differences apart from the version tags after comparing the mp3's produced with -apfs

Actually the a12 .exe is 181kb while the b1 .exe is 163kb.

Supposedly, it isn't out yet (or the CVS changelog isn't up to date?)

LAME 3.97 alpha (CVS)

Robert Hegemann:

Fixed and out of array access
Fixed some small rounding problem in vbr-new quantization routines
Updated scalefactors allocation scheme in vbr-new
Fixed mingw32 configure problems
Resolved some compiler warnings

Gabriel Bouvigne:

Changed some FLOAT8 to FLOAT
Reworked -q1 and -q0
Updated presets
Fixed an error in ISO quantization on systems not using the IEEE754 hack
Faster quantization
SSE version of init_xrpow

See the 'history.html' in the download.  In quality terms, I believe there is little, or no, difference between a12 and b1.

Can you prove this is a "great" present, do you have ABX results?

JK, Happy Birthday, Leo 69!

i was just thinking the same thing!  today is my birthday as well.

edit: btw, shouldn't this be an official announcement?

i didn't feel like starting a new thread for such a simple question, but i was wondering if it made any sense to use -q 0 with -V2 --vbr-new.  I know it will slow down encoding time, but if in some cases it will pinch out some extra quality or cut out some bits, it may be useful to me.

AFAIK they fixed the old bugs in -q0 and -q1 during 3.97's alpha stage so assuming there aren't any more unknown bugs it should be safe.  Now whether or not you should use them is an entirely different matter

Is vbr-new default for "vbr" mode in beta1?

the apelllation beta affords some psychological comfort ;-)
The regression report inclines me to use V0, q remaining the same.

No. Could one of the developers please explain what is planned in this regard?

I see that there is a slight speed drop in vbr_new on my machine:
397a12 --vbr-new: 16.2x
397b1 --vbr-new: 15.5x

The differences down to vbr_old is getting narrower:

397b1 --vbr-old: 11.0x

It varies slightly on different music.


edit: When I ran another sample, I still found the speed drop, but also bigger differences between old and new (which it should be).
397a12 --vbr-new: 17.2x
397b1 --vbr-new: 16.5x

397a12 --vbr-old: 10.2x
397b1 --vbr-old: 10.2x

w00t!

Lets hope for a final soon.

Edit: If --vbr-new is said to produce the same, and in some cases slightly better, results at a faster encoding speed than the standard vbr algorithm, then why is the standard algorithm even included? It makes much more sense to just remove it and set --vbr-new to default, IMO.

Vbr-new will probably NOT be defaulted in 3.97. While this vbr mode itself seems fine, defaulting it is not tested enough and would require differing release.

As it has been a long time since last release, and as 3.97 should bring significant improvements compared to previous release, it is released but featuring the legacy vbr mode as default.

I think --vbr-new should be recommended in the new "Recommended Settings" thread, so people start using it and report failure/problem cases.

Is it now "safe" to use 3.97b1 instead of 3.96.1?

the newer vbr code hasn't changed for quite some time, so there should be no speed decrease. what exactly is your commandline at full length?

Sorry, guys, I had compiled using the stock options rather than those that I normally use.  I've recompiled and uploaded again. The speed should now be as before.
