A personal LAME APS problem tracks test.

Lately i keep finding troubled tracks on my music collection (and still finding  ) that are encoded by LAME 3.97 -V 2 --vbr-new, for some reason i am picking up artifacts more easy and i have not upgraded sound hardware and did not do any artifact training. Am shocked that i managed to ABX those tracks with a cheap Sound Blaster Audigy SE sound card and my Sennheiser HD 202 headphones.

Am not sure with this encode i keep thinking there is something wrong with the cymbals in backgroud.

At the moment am finding LAME 3.98b to be better then LAME 3.97 at V2 and better or good as LAME 3.90.3 --alt-preset like on my early findings a few months ago.

Which compile of 3.98b6 are you using for your test?

EDIT: I just noticed the Nov 1 in your post... you should check RareWares, I think it was updated today.

You could try -V1 then --abr 260.. If you can still abx here and there, you might just have to accept that mp3 is not fully transparent to you.

I used the Nov 1 build, but beta 6 is not offical build its a CVS fork of updates and it some has a major bug fix from beta 5.

You could try -V1 then --abr 260.. If you can still abx here and there, you might just have to accept that mp3 is not fully transparent to you.


I tried -V 1 --vbr-new on LAME 3.97 on some tracks i found a few months ago that was transparent or just sounded a little better and V0 did not make a difference at all over V1. And ATM am finding V0 to be useless and a waste of space since it can be possible that its not transparent on tracks that struggle at V2 and just sounds a little better and gain 10mb - 20mb on a album at V0, and i keep getting bitrates at 280 on V0 so i might use V1 instead or just stick to V2.

a) With pre-echo we have to be content with a rather modest behavior when using mp3 I'm afraid. But as you've found out there is still progress with Lame, and as you're sensitive towards pre-echo you may have your part in further improving Lame.
b) From former listening tests I also experienced that going from -V2 to -V1 can improve certain problematic samples in a meaningful way, but going from -V1 to -V0 isn't worth the price. But you may consider trying --abr 260 or similar as shadowking suggested: if you allow for very high bitrate this is the best way IMO to get at the best quality possible. This experience of mine is based on non-pre-echo problems and 3.97. 3.98beta's psy model/VBR method has improved a lot since, so this may not be valid any more. Anyway I would give --abr 260 or similar a try.

I could give ABR 260 a try or 230, but i did try ABR 128 on 3.97 a couple years ago but i found it sounded the same or just a tad better then 128 CBR but that mode was using very low bitrates anyway, but ABR could out-perform VBR if the ABR target is over the VBR mode target since ABR target will be fixed.

The main difference between VBR and ABR is to me: the bitrate control of VBR relies very much on the psy model whereas the bitrate control of ABR doesn't, and bitrate variation of ABR is more conservative as a tendency. At very high bitrate like 260 kbps the advantages of ABR are more important IMO than the disadvantages: bitrate is very high at any rate to ensure transparency in most cases, and those rare situations where the psy models flaws doesn't have the same bad impact it has when using VBR.

So the situation with very high bitrate is quite favorable for using ABR - quite a different thing then when using low bitrate.

Whether or not this improves things for your pre-echo problems is another story. As a tendency VBR usually does a good job here. Anyway I would give ABR a try.

Your reasoning makes no sense because even in ABR mode the psymodel still controls the bit allocation, and just 260kbps, let alone 260kbps average, is not enough to guarantee transparency in critical situations.

If the psymodel is truly off, the instantenous bitrate at that frame should be (very roughly) >368kbps to ensure no artifacts can happen [1].

ABR will not protect you from that and will constrain the encoder when it KNOWS it must go up to the maximal bitrate.

So think: what is the more typical case, the psymodel is right or the psymodel is wrong?

[1] Gives about 18dB SNR over the entire frequency range.

The logic is simple: The higher you go with ABR bitrate the better gets the chance/risk relation of using ABR vs. VBR simply because you can't get better than using 320 kbps frames, and because of the fact that VBR introduces a certain risk. That's why you can read of ABR in the Lame documentation as being the 'safe' vbr method. BTW due to restrictions of some encoders concerning bit reservoir usage of 320 kbps frames it can even happen that you get at a better net audio data rate when using 256 kbps frames at a critical spot.

Anyway that's theory. I do have some experience with problem samples behaving better with ABR at ~260 kbps, but these weren't pre-echo samples. For pre-echo issues I doubt ABR will improve things but would give it a try.

You might give the 10 Dec. 07 b6 compile on Rarewares a try to see if it has gotten any better than b5.

I gave up on LAME V2 because on my home stereo system, which is a fairly decent (not very expensive though) system... I can't take MP3's anymore... They pretty have a little less of bass frequency. The original CD's have got just a bit more bass and punch.
Care to put some objective proof behind these flippant and ill-advised remarks?  Need I remind you of TOS #8?

It could be bad decoder or equilisation, hardware fault. I suggest getting some dedicated mp3 device for reproduction.

I have done a quick test on the new build, also now LAME 3.98 now has a new psy model that is a based on nspsytune and is on default on vbr-new so now lame 3.98 needs more listening tests.

This encode sounds then the other versions of LAME i tested, or i got more sensitive towards pre-echo  but on LAME 3.97 i find this track to be transparent at V0 -vbr-new on but can ABX it easy on V2 and V1 -vbr-new.

I found yet another precho artifact on track when i was trying out -V 1 --vbr-new on 3.97, which is transparent on 3.90.3 APS. The track is Back The F**k Up by Fear Factory from the album Digimortal, also I do have another track from them (Replica) that is not transparent on V2, but not tested that on higher setting atm.

Very strange, no precho artifact this time. For reason at around 0:29 - 0:33 seems less audible and lifeless on this encode, like some sounds have been removed.

After playing with V1 and V0, I found that V0 seems to be really pointless if you can ABX V2 and only sounds a tad better or sometimes transparent at V0.

I was gonna ABX the precho the artifact at 0:12, but I just found and ABXed this psst pop (precho) which which appears alot on the eig sample, but it is hard to notice if you are not concentrateing on the track.

I tested on 3.98 Beta 6 at around 0:12 and got 18/23, sometimes I could hear the artifact. But my hearing has gotten abit bad or back to normal every since I had flu at the Christmas holidays, I now have trouble ABX some the tracks I did a few months ago.

this is all heavy metal, right? it may just be the particular kind of music not to be very friendly to mp3.

Well most of the time I keep spotting artifacts on drums on metal,I get the impression that LAME really hates Industrial Metal.

A precho at the start sounds better then the 192kbps encode, but worse then the 224 encode.

Sounds better then 3.97 possibly sounds the same as the 224 cbr encode, but -vbr-old (LAME 3.97) sounded better.

/mnt does this go away at 320 CBR 3.97 final?

I had a quick test at 256kbps CBR by using --preset cbr 256 and got 7/12, I struggled to ABX with this sample and also its getting late when i was testing it. I think it should go away at 320kbps, but like most of artifacts expect Stigmata by Ministry I picked up on my music collection goes away when I crank up the voulume which disorts the artifacts away such as Harvester Of Sorrow.

Just did a test at preset insane (320kbps cbr) and got 7/12, I struggled with this test aswell I think it is transparent, but sometimes I think I might have heard the artifact. Anyway this sample shows that V2 is better then 192kbps CBR (it should anyway) and going from 192kbps - 224kpbs CBR can make a difference.

Any conclusions yet?

Could you somehow say that there's less artifact with V2 than wth V0

If that means me: No, according to my experience -V0 is better than -V2 at least on some occasion.
