I think its not a good idea tweaking the Lame settings for my test. It goes against the HA mantra of "NEVAH tweak the presets", so it would not be representative of what forum readers use.

Well, it's not that much tweaking, after all in 3.95 --preset 128 is just --abr 128. But I agree that it is not very representative of real use.

Gabriel, could you please tell me the tweaked preset for a bitrate around 128 kbps ?

It would be nice if some users will perform individual tests with --abr 128 and --abr 128 -q0, before the end of the test. Then Roberto may post something like an appendix, or a comment as conclusion about the (possible) benefits of the -q0 switch. What do you think?

I think that at 128kbps the benefits of q0 regarding quality are clear. But it does not represent how users will be using Lame.

I agree with Guruboolez' idea, an appendix would indeed be better, specially considering usage representativity.

Hello.

I'd like to ask if anyone here is experiencing problems to reach the listening tests site -
http://audio.ciara.us/test/

It's been weeks since I could last log into it. If it's only a DNS problem in my ISP there are no worries, it should get fixed sooner or later. But if more people are having issues, I'll need to move it again.

Verloren, can you help? I can't login through my FTP account either.

Also, I couldn't login using HA's SSH server + lynx.

Weird...

What's worse, I can't use the FTP account to upload the presentation page. So I guess I'll have to move the site to rjamorim.com anyway sad.gif

I'd like to point that with 3.95, targetting 128kbps I think that -q1 and -q0 can really improve encoding quality.

is it possible to use this setting along with aps? How much longer would that take? I mean it says in the ChangeLog that the new release is 10% faster, so what's the deal? I rather wait a bit longer and have a smaller file or a file with better quality...

Yes, of course it is. Just add -q ??? after --preset standard.
But the test should be based on standard setting.

Very short speed test:

Both compiles are ICL 7.1 by john33, most probably same optimisations...

does this actually mean that the standard setting is an abr (JS) mode instead of cbr (Stereo) like it used to be?


--------------------
--alt-presets are there for a reason! These other switches DO NOT work better than it, trust me on this.

The default encoding mode in Lame is still cbr/128/JS.

Btw if you want to know what is the default mode, you can try it.

-Xing 1.5 VBR quality normal
Is that the newest version? I just read that (by Karl Lillevold: http://www.hydrogenaudio.org/forums/index....ndpost&p=173122):

P.S. I have been told the Xing encoder is much improved since its first incarnation, which is usually not well spoken of crying.gif

You can also download a free plug-in supporting all bitrates encoding for RealPlayer. I would really like to see (confirm biggrin.gif) how bad it performs against Lame & other encoders using short blocks. I would be rather suprised not to see Xing at the last position, but this test could show the truth.

As you can read some posts above this one, I had no luck installing RealOne. So, no, sorry, this isn't the latest Xing. There's nothing I can do about it sad.gif

BTW, test is now OPEN.
