Ok, it is totally understandable. I was just so excited after my own experimental tests with the new encoder.

Maybe there is a chance to organize a new test sometime in the near future, maybe HE-AAC test ?

Perhaps, and please realize that anyone else can conduct/host such a test, assuming he has the time and resources.

In the meantime, let's keep this on-topic, please.

@jukkap

Can you open the new topic and tell us more about upcoming Dolby Pulse AAC encoder? smile.gif

You could also do it in winamp if you manually edit the encoder settings INI file (i think it's %appdata%\winamp\plugins\ml_transcode.ini), although the configuration UI *might* revert to a different bitrate when it gets displayed. You could uncheck "show me this every time" in the pre-transcode configuration UI to avoid that, though.

I have encoded the CT files this way. It works. Thank you for explanation.

Some notes:
FhG 1.01 was used for this test. http://www.hydrogenaudio.org/forums/index....st&p=761865
Low anchor is ffmpeg's AAC but at 96 kbps http://ffmpeg.zeranoe.com/builds/win32/sta...win32-static.7z
128 kbps was too good to be the low anchor. lvqcl was right about it.
It was proposed some time ago to concatenate the sample because CVBR has some not constant behaviour on some samples.
But the downside of concatenation that it's invasive for encoders. So we would solve one problem but create another ones.
I wouldn't worry about CVBR as it has produced the same bitrate distribution on the test samples as other competitors.


Here is a complete package (ABC/HR and all samples). www.mediafire.com/?q3lrkb3ogll8jdt
ABCHR configurations for verification http://www.hydrogenaudio.org/forums/index....st&p=763167
Please, check all conditions.
If everything is good then the test will be open this weekend.

Sample 01 - Reunion Blues

Sample 03 - Berlin Drug

Sample 01 - Reunion Blues

Where does that come from? In the Samples_selected.xls posted by Steve Forte Rio, there was a "1.flac" which seems to have been replaced.

Not that I care much, but what was the reason for this change?

And another kind request: Please check for artifacts in the 20 Winamp encodings which are similar to the one Alex B described. These reveal a (rare) bug. I did a brief test and couldn't find any, so that bug doesn't seem to show up in the test samples, but I'm sick at the moment, and my hearing sucks.

Thanks,

Chris

The samples are the same.

Reunion Blues is ''Jazz''
And "1.flac" is Smashing Pumpkins - Earphoria

I haven't found any issues. Some loud samples like 7,8 and 17 were suspicious at the first time but I couldn't hear anything wrong with them.

Igor, I was just asking two simple questions. What is the problem? You were asking to "Please, check all conditions.", so I did a bit of that.

Chris

Hm, I can't see a real good reason why FhG encoder shouldn't participate.

Though Chris' questions probably have in mind giving 'his' encoder good chances I can't see a real inappropriate behavior.
In case you find it inappropriate to answer the question for a change in samples (not my opinion), you just could refuse the answer.

I'd find it great if you could give FhG another chance.

Igor, I think your decision was overkill. FhG encoder is one of the most interesting participants in this test. Could you give it another chance?

Chris, I understand your interests here (particularly your concern over the samples selection).
This test is public and fully transparent for everyone. But you have to agree - this peculiarity mustn't negatively affect it's success.

Hopefully, we'll settle this conflict as soon as possible and will return to our independent testing.

IgorC, final warning. Either you continue the conversation and the test in a civilized manner, or you are on your way out here.

In fact I'm also very interesting to test it. So it's in.
I hope all previous disagreements were just misunderstanding (not English native speakers) .

QUOTE (menno @ Jun 28 2011, 17:53) *
I don't think it's a waste of time to test FAAC, by far most AAC content is encoded with it, especially in the 96kbps range. Testing FAAC can provide clear and up to date argumentation for why many internet services should or shouldn't keep using a free solution as opposed to a commercial solution.

Hi menno, long time no see. Could you tell me which internet services use FAAC at 96 kbps (YouTube within the FLV/MP4 format?) or maybe send me a PM to avoid off-topic postings in this thread? smile.gif

Until the beginning of the test I want to say how it's important for me. A lot of people (including me) have waited a lot of time for such test.
We will test commercial LC-AAC encoders and it will be my responsibility to conduct it in fair and open manners.
I expect the honest attitude from all interested parties and participants. We will control the results.
All you have to do is rank the competitors basing on what you hear smile.gif


I will ask administrators to close this topic. The test will begin shortly.
