I found a really bad killer sample., Very easy to ABX with any mp3 encoder at 320 kbps.

I've seemed to have come across a track from my flac collection that has a really bad precho problem, just like eig. At the very start of the track it has artifacts and is even ABXable at 320kbps.

LAME 3.98.2

I confirm at Lame V2, I wasn't able to take V2 faulty in my own comparison so thx for the sample, I may add it.

one second of this sample is enough I hear a distortion (like sand on a drum) on the third beat exactly, I didn't bother listening to the rest of the sample.
If you have other ghosts like that in the closet i am interested, I will have a look at this eig sample if I find it.

Does anyone know where it comes from Artist/Album ?

PS: I am searching for these ones too Electronic: Spahm (trance music), Amnesia (acid music), I heard pio2001 speaking about these.

Thks lvqcl,
as soon as I get some time I will add these two samples to my comparison, because both illustrate that lame is not transparent as V2 which my table doesn't actually show. I also need to see if Nero q0.55 still achieve transparency on these two really bad ones.

Theres a album track by Skinny Puppy that has some bad precho problems at the start with most encoders at low and mid bitrates. Also Linchpin by Fear Factory brings Nero AAC to its knees.

Huston we have a problem.

I tried to edit this sample in order to make it shorter & focus on the 4 sec (specially the third beat) that I can ABX & I had a big surprise: when encoded to lame V7, the artefact moved within the sample blink.gif

If you encode the original sample to V7, you have a big artefact at the start, on the third beat.

If you encode my shortened version of the sample, you have a big Artefact at the end of the sample that is not here in the long version of the same sample encoded at the same lame setting (V7).

First I thought that I cutted the sample at the wrong point with audacity, but I wasn't the case. Then I thought that the artefact was masked by the following sound, but it wasn't the case too.
I was so surprized that I decoded to wav the long sample encoded to V7 from the original & I edited it to match my short V7 version.

I discovered that the original & the shortened sample didn't react to lame V7 the same way at all despite the fact that the original audio data is the same.

Within the original 30 sec sample the major artefact is at the beginning.

Within the edited 4 sec sample the original artefact is here but much softer & there is an additionnal major artefact at sec 3-4 that is not here if you encode the original to V7.

That is very very strange. I dunno what to do with this sample for my own listening test.

If each time you edit a sample the encoder reacts a different way, this is a problem for any ABXing tests.

I dunno if this is a lame bug or if this is normal. Some people told me to use longer sample, but that doesn't change anything, it seems that with lame each edited version will "maybe" react differently.
So you have to compare the original version Vs. the encoded version AND the edited original version Vs. the edited encoded version ... I doubt anyone did it in previous listening test.
I hope this is a lame bug because otherwise this is very annoying for any listening test. I didn't test on other codecs to see how they react.

Well I can still ABX the same kind of artefact on this sample, so in the end it does make a killer sample a normal sample, but the fact that this soften the first artefact is a real problem.

crying.gif I am completely perplex. blink.gif

Edit1: There was some silence in the beginning of the original I will edit the long version without removing the silence in the beginning (only cutting the end) & see how it reacts ...
Edit2: It reacts as the original if I don't cut the 0.35 msec of silence from the beginning ... so it seems you can cut the end with no problem but not the beginning ... I was warn but I didn't thought it was so severe ... because it affects music at up to 4 sec after the beginning ...
Edit3: Silence or not it shouldn't be different. It is still strange, because it's music that is supposed to affect the model, not silence.
Edit4: I tried to add 35 millisecond of artificial silence to the short edited version. I end with a new beast: even softer artefact in the beginning & no major artefact at the end, it's making me crazy wink.gif
Edit5: I copy/pasted the sample to have it twice (X2) in a row within the same sample, the result is (soften artefact+major artefact)+(soften artefact+no artefact). Seems the longer is the sample the softer is the artefact. But you cannot say the more there is silence in the begining the softer the artefact. Very hard to predict.

Edit6: Deleted attached files, attachement limit reached.

It appears at around 0:03 - 0:04, instead of the first second.

I think this might be a block usage detection issue, which the mp3 codec can have limitations on with certain samples.

This problem is almost the same problem i have with this track thats not transparent on LAME V0 but sounds fine on V2 huh.gif

Smear and warbling at 2:42. Shares the same problems with Die in a Crash, which is also easy to ABX at V0 while it sounds better with V2.

Then i decide to make a sample of this track:

@sauvage78:
You might consider removing multiples of 576 samples (if no resampling is involved) or multiples of 1152 samples (if LR/MS stereo mode switching is critical).

I made another edit of the hard to encode track at 3:00 - 3:20 were it sounds really bad. Am shocked that a single track can have soo many artifacts that is even audiable at 320kbps.

Encoded with LAME 3.98.2 at 320 kbps CBR. Major precho artifacts.

Temp upload for this post.

Edit

I added a few more temp uploads to report a bug on foo_gep.

I tried out Vista again and spent about a few hours just to install Service Pack 2 and a shed load of restarts (I've should have made a streamlined copy instead). After playing music foobar2000 under Vista and notice this sample sounds bad on Vista's mixer but it sounds fine if I use foobar's WASAPI output plugin. But am not sure how to ABX the Software mixer and the WASAPI output together, to proof my claim.

QUOTE (sauvage78 @ Mar 22 2009, 10:18) *
PS: I am searching for these ones too Electronic: Spahm (trance music), Amnesia (acid music), I heard pio2001 speaking about these.


Hello,

Here they are :
Amnesia
Spahm

Beware that Amnesia has been normalized. Check for internal clipping when you make an mp3 of it.

I recently ABXed spahm in mp3 at 320 kbps, with Lame 3.98.2.

I didn't try Amnesia. Originally, it was a problem with Musepack more than mp3. The sample is semi-artificial. The original has a much lower volume and causes no problem with Musepack.

I've uploaded some samples from Kraftwerk's epic album, The Man Machine. Which is very easy to ABX at 320kbps with Mp3.

Uploads for this topic.

Those samples are ABXable at 320kbps Mp3 to those that are sensitive to pre-echo.

Please note, that ptp_robocop.flac is a edit version of Show Me Your Spine (3:00 - 3:30) and the_robots.flac is a different edit from orginal the kraftwerk.wv sample from a recent remsatered release.

An re-upload for this topic.

Most of those samples on this zip file are also ABXable on modern codecs as well. For example Ogg Vorbis fails badly at the start on The Robots.

I am so glad I can't hear these differences.
Does it mean that I can't hear anything else and rest in peace in the lossy realm?

/mnt is very sensitive to pre-echo problems, much more than most of us.
This is very good for getting experience with codecs' issues when using very high bitrate, but you shouldn't care if you can't hear issues /mnt can hear.
