It's not a first time You make unverifiable comments. Actually, there are many of them.
So stop  f talkin  and start actually backup your statements.

I am with IgorC on this. You only add to the discussion if you back up that claim ...
Thank You!  Most of us here agree on that.

No, Most DO NOT agree. That is a lie . People that know me since 2004 , know I am reliable.
I been here 16 years + . You don't come and tell me how its done .

Man, just see what people have responded to You in this topic.

I will test your test case as per above. So I will play ball. but none of your links has any ABX proof that they can actually ABX the difference even on that sample. Yeah, I hear it is easy. Then give us some proof.

It seems like a bunch of you are in an echo chamber. This is not how Science works. Just parrotting the same thing along with a bunch of others (who might have picked up this from you) proves nothing. This is not a competition how many others I can make to parrot the same thing.

The thing is Vorbis is better than Lame is 99% by a large margin. You will have a tough going to prove otherwise. So even if there is one sample, at least we should keep in perspective (and have proper documentation of that rare case).

Yes vorbis is better, I never said otherwise. It was another poster.
Since aotuv, tests show its very good. That's what I said.
i said 'may be edge cases' like this that I stumbled on in the past.

Why should you not believe me ?
I find an issue with software ; lossless or lossy. Say wavpack. Okay ?
I contact the developer - a very respectable individual BTW.
I don't get asked to prove anything. He will check it to confirm because there's an
interest to make software better.

That's how that one particular developer manages things.   That's ok for him.

You are not contacting him right now, You are posting in Hydrogenaudio and You should be TOS8-compliant > Terms Of Service

Even if You were Paul McCartney ( he is even more popular than You) you would still need to provide a downloadable sample and ABX log. TOS8 isn't optional.

P.S. We don't have this discussion with Kamedo2, Guru, /mnt  even me  :P  .... even if they are reliable they still provide all kind of information. No need to ask anything... everything is available!

Yes to prove one codec is better than another codec. I never claimed it.
I said codec vorbis has bug on this sample .  Like amnesia & fsol samples mpc q5 was
worse than lame V2 but no one said mp3 is better than mpc ..

Q6 - I started here and it seemed harder than I remember. Vorbis got better since 07 or I got worse (probably)
So.. after going to Q4 , I decided to do another round of Q6

Q6 -first test. Bitrate 252k

15 / 18 for Q6

trial reset was I decided to use a different position for playback.
For that position score is 7/8 + 7/8 = 14/16

total all: 8/10 + 8/8 + 7/8 = 23/26

ani_Jackal3 has just disappeared now that his unfounded statements were laid bare. It is good for the forum that we have less BS.

 I just want to put my two cents in on this...

As a test, I encoded the same audio file into four codecs, MP3, Vorbis, Opus, and AAC, at 128kbps and 64kbps. Relaying the facts based off of a spectrogram:

* 64kbps Vorbis filtered out frequencies past around 15kHz
* 64kbps MP3 filtered out past 11kHz and 128kbps MP3 filtered out past 16kHz
* Vorbis 128kbps, AAC, and Opus didn't filter out much
* There is a part where the right channel is the inverse of the left channel -- Opus stays the same in quality, AAC filters it out entirely, and Vorbis and MP3 drop greatly in quality.

I personally dislike MP3, because at almost any bitrate, it brickwalls a lot of frequencies. At 128kbps, you really won't be getting much past 16kHz in any audio file, and less if you chose to use simple stereo instead of joint. I can see this in these spectrograms, and hear it too with the 64kbps MP3.

From my personal experience, Opus does the best at low bitrates (64kbps here), almost tied with AAC SBR+PS. However, it's up to you to determine which sounds best to you. Once, I encoded a track with something like 48kbps Vorbis and there was a lot of high frequency content not present in the original song. It actually made the track sound better to me, I shared it with someone else and they didn't like that. It's entirely subjective.

Thx for contributing another baseless assessment on this thread which is rife with this. There is no point looking at the spectogram. The fact you look at the spectogram means that you do not bother to do blind tests, and you learnt nothing on this forum.
