Full Version: Fifth competitor for 128 kbps listening test
Hydrogenaudio Forums > Hydrogenaudio Forum > Listening Tests
Sebastian Mares
Hello!

Since WMA Standard 2-pass VBR at 128 kbps cannot be used on small samples and WMA Standard VBR Q75 produces files with a bitrate that is too high, we are left with the following options:

None: Feature 4 competitors and 1 low anchor only.
WMA Professional, VBR Q50: This codec and setting produces an average bitrate of 134 kbps. The drawback is that the format is not very popular yet (not used in music stores, no portable support).
WMA Standard, VBR Q50: Personally, I see no sense in testing WMA Standard at Q50 since it produces files with an average bitrate of 104 kbps which is way under the 10% tolerance. If WMA should lose, it would be meaningless since it was handicapped by the low bitrate compared to the other competitors.
MusePack: Include MusePack in the test, although it has a lot of disadvantages.

Edit: Could a moderator please make this a poll only? I don't want replies.

I have a feeling that the results are going to be 25% / 25% / 25% / 25%... dry.gif

Why not 2-pass cbr? They provide such function too.

What functions? blink.gif And didn't I say I don't want replies? Why can't people respect one's wishes? dry.gif

By the way, the poll will run until Tuesday (presumably).

My opinion is that we will get more meaningfull results if we don't try to test everything at the same time. There will be less results, less variation when the codec count goes up, and this is especially something to consider for 128kbps test. This wouldn't be so big problem for a low bitrate test.
Better would be to arrange another test relatively quickly after this and include some other codec/codecs, and keep the total codec count down.

IMO, that would be a waste of resources. When doing such a big public listening test, I think we should test as many encoders as we can and 5 seems reasonable to me.

WMA Pro without a doubt

Yeah... dry.gif

At least I don't have to read 100 pages to see the outcome of this discussion.
JohnV
Well, in my opinion it is indeed waste of resources to try to make people find differences from 5 different codecs at 128kbps most of which are probably better than last time, because I can imagine it's hard for many people and that reflects to results.
Listening fatigue plays so big part here, I can say this from personal experience.

I have to agree somewhat with JohnV. If the time to participate was a bit longer than usual (some of us have lives elsewhere you know, we can't listen for several hours a day... <sniff>)
Sebastian Mares
This is exactly why I wanted a damn poll only. I have the feeling that this is going to turn out into a huge bullshit like the other thread did.
Can't you people simply vote and shut up? tongue.gif happy.gif

The test will be longer. It has been mentioned AT THE VERY BEGINNING of the test discussion thread.


Also, WTF is wrong with you guys? Can't you respect a single request?

1st of all, not long enough to some of us sad.gif

Second of all, what's wrong with discussion, calm down dear man smile.gif

This is exactly the kind of attitude that keeps people away from this place. We just want to get along, so please calm down.

Yes, but I asked you to please, please, PLEASE! not reply to the thread.

Edit: And 20 days is plenty. If you can't test all samples, you can test only half of them or whatever.

Thread closed, you can bitch in the Multiformat 128 kbps Listening Test, Pre-Test Discussion thread. I know I will. wink.gif

Edit: OK, thread is open again, seems it's not possible to vote when the thread is closed. You will have to deal with the replies. tongue.gif

Edit2: OK, should be "vote only" now.

If I am not mistaken, IPB supports creating polls only. I think you as moderator have the option to edit the poll only and tick a checkbox that reads "Make Poll Only" or something like that.
