Lame 3.98 beta 6

Updated : lame 3.98 beta 6 (small fix) (2008-03-12 13:47)

Sources : http://sourceforge.net/project/showfiles.p...;package_id=309

Binaries : Rare Wares

CVS : http://lame.cvs.sourceforge.net/lame/lame/...me/?sortby=date

Official LAME v3.98 Beta 6 is out on December 16 2007:
  • Robert Hegemann:
    • Feature request [ 1811483 ] WAVE_FORMAT_EXTENSIBLE support (PCM)
    • Fix for some rare scalefactor selection issue the newer vbr code had at low compression levels
    • Fix for Bugtracker item [ 1813496 ] AIFF parsing bug
    • Latest changes to the new VBR code:
      • it now has its own psy model, a derivation from NSPSY.
      • some more tuning has been done for this new psy model. Many thanks to Horst Albrecht and Myles Thaiss.
      • the "out-of-bits" strategy is reworked
    • It was possible, that the "interchannel masking effects feature" was used by the dual-channel-mode for bi-lingual encodings too. It was meant to work on stereo L/R channels only.

Can someone test with new killer samples??

For my personal use and maybe if someone wants to test beta 6 out on a Macintosh computer (and isn't command line savvy), I've compiled Max w/ LAME 3.98 beta 6.

also the command line version in universal binary goodness

EDIT: Compiled again for the changes mentioned below

Did a quick test with -V2, for some reason this version produces smaller bitrates then beta 5 and 3.97.

Sounds the same or worse then beta 5.

Here is another killer track I have that is not transparent on LAME 3.90.3 --alt-preset standard and also not transparent on LAME 3.97 -V --vbr-new.

This track was transparent on beta 5, but it not at beta 6 and the beta 6 encode produced a smaller bitrate while ogg at q.6 and nero aac q.55 was in bigger bitrates. So far this the worst encode I heard of this track it also has the artifacts that were on -V 5.

LAME 3.98b5  205kbps
LAME 3.98b6  187kbps
LAME 3.97      187kbps

A hard to hear but not annoying warbling at 3:58, but my ears picked it up like there is something wrong.

This encode also produced a smaller bitrate then the past version i tested 192kbps LAME 3.98b6, 211 kbps LAME 3.98b5, 200kbps LAME 3.97 and 220kbps LAME 3.90.3. I find this version be worse then 3.97 and I find beta 5 to be better then 3.90.3 and 3.97.

/mnt, you make me go lossless all the way...
I wonder if you can ABX OGG at q.6 with the EIG sample.
it's so weird these new LAME versions not handling a lot of things...

Codec development is a challenge, and this is especially true for mp3.
The ways towards improvement are not wide and straight.
It's always weighing advantages vs. disadvantages of a certain approach according to experience.
That's why /mnt's findings are so helpful, and why a forum like this is important where members are invited to contribute and share their experiences.

A bitrate test on 1 song:

3.98 b5 - V4 vbr new = 159 k
                        old  = 158 k

3.98 b6 - V4 vbr new = 150 k
                        old  = 133 k  !!

25 k difference is too sus..

Looks like --vbr-new got recalibrated due to a bug fix.

http://lame.cvs.sourceforge.net/lame/lame/...tize.c?view=log


Its hard to believe that a late beta has such a bitrate gap - 10 k for vbr new and 20k for vbr old. All vbr is different.

Since me and others were very happy about the quality improvements with b5 i hope the devs donĀ“t want to please the few that complaint about a bitrate rise to 3.97.
Is troll-adiposity coming from feederism?
With 24bit music you can listen to silence much louder!

It looks like a bug or something. vbr old is 30 k lower than B5. I confirm it with another track: 163 k B5 vs. 139 k B6

Thank god I can not ABX EIG (i tried my best) on Ogg at q.0.6 and Nero AAC at q.0.55, but on mp3 its very easy and so for I find iTunes mp3 encoder to do worse on EIG and it did worse then the first verion of l3enc

I gave up at 8 because it was torture, sounds like a encode from a very old version of l3enc.

A nice improvement from 3.97, but still not transparent at 0:11 was louder and still had artifacts awell but almost acpectable.

New builds at Rarewares now.


John, the LameDrop link for version 3.98b6 seems to be wrong ; it gives me the cli encoder package.

You did not notice the difference with NERO q 0.55 ?
Which Nero Version did you use?

This is a case of selective perception aka ""Hasty Generalization" and "Proof By Example". Both are typical mistakes made by "paranoid" and "idealistic" minds.


The dogmatic strange devoted phylosophic writing-like you do reveals deeply to me that you have a strong religion inside your heart. Your religion is SCIENTOLOGY!!! LOL

"a lot of things" meant irony in case you didn't know. But you HAD to take it to the religious path... oh boy....

I used Nero AAC codec / Feb 12 2007 build since the latest version produces a horrible metallic warbling noise on some AAD mixed songs such as Iron Man by Black Sabbath.

I tested 3.98b6 -V2 with Birds, eig, harp40_1, herding_calls, lead-voice, trumpet, and trumpet_MyPrince.

On the positive side is harp40_1 which was pretty hard to abx for me at -V2.
eig is good too with respect to this extremely hard sample.
The trumpet_MyPrince tremolo problem near the end is also very easy to accept.
Everything else was as expected with the exception of trumpet: second 2.6-5.7 isn't good (also a kind of tremolo) and easily abxable 10/10. I rechecked with 3.98b5: same thing here.
Very strange as I was convinced trumpet wasn't a problem any more due to earlier listening tests with 3.98.I remember having heard it before but either has it turned more serious or may be my listening sensitivity for such a kind of problem has "improved".

Out of curiosity I also tried --vbr-old with these samples. --vbr-old is so clearly worse on nearly all the samples that I suspect there is a bug with --vbr-old. It's very pronounced with lead-voice and herding_calls.
