I just tried again at Q4 but still couldn't ABX. I am quite tired though. I didn't test beta3 at Q7 because I had already failed at Q6. I will try when I am less tired.

I've uploaded a sample, mpc --standard fail on this sample, I think it's an interesting sample to test with aotuvb3, the quality setting I've tested is only -q 4 , i get 8/10

I vote quality -0.01 for best size/performance trade-off. The bitrate here is in the mid-50s but it's rather listenable without much unpleasantries.

Subjectively, quality -0.01 is more agreeable to my ears than quality 0. Why is that? The jump to -q 0 involves a different intensity stereo tuning...and I think -q 0 makes the stereo image too wide (for the nominal bitrate) and it just sounds more "artifacty". The more monophonic -0.01, while less accurate, nonetheless sounds "better" especially with its ~10 kbps bitrate savings as a sugar coating.

@Yaztromo
About the problem samples of q5 and q7, I will check carefully and will try correction.

@kotrtim
It is a good sample. This type of sample is one of the weak points of present Vorbis Encoder.

@mithrandir
As for the threshold of a stereo,q0 is better than q-0.01.
However, a different result will be brought from the difference in block size and other parameters, etc.

Why oggdropXPd and Cool Edit Pro filter compiled using aoTuV b3 doesn't support encoding parameter q -2?

Because the code hasn't been modifed to support it. I'll take a look at it.

Thanks, John33
Is it possible to compile oggdropXPd using new, optimised for speed, patches by Archer? Actually, Archer already compiled oggdrop, but only in Japanese
English version will be very welcome

I did d/l the code, but I've done nothing with it as yet. Maybe over the weekend?

Compiles in all flavours of oggdropXPd now at Rarewares with support for quality down to -2.

cool_vorbis filter with -q -2 added as well.

John33, You are wonderful!
Thank You very much

Some regressions noticed with beta 3 compared to aoTuV beta 2. More details on this post.

Hello,
I've got some questions as a newbie to the ogg format.

So, I like to use ogg format, because:

1. My Iriver IMP-550 finally supports OGG (with Firmware >1.50)
2. I found a really good DJing software that supports it too (DJDecks which just costs 25 Bucks!!!)

So, I've copied the aoTuv Beta3 files to my Foobar Folder and converted a CD (Radiohead - KidA) inside with Foobar Quality settings 2 4 5 and 6.

then I tested it on my Iriver.
But for me I can't really tell much of a difference between 4 and 6. (All sounded very good to me)

and 2 unfortunately doesn't work.
I think because of this.

The Bitrate of 2 is simply too low

But I said I had some questions,
So, Should I generally stick to Ogg? (as my Players support OGG,MP3 and WMA)
And wich quality should I use? (listening to anything from 60's Rock to Acid Jazz, generally all that's a bit psychedelic. So Stereo should be good)
and is the encoding I do right ( I mean with Foobar), or is there a better way?
also if I convert FLAC MPC ... to Ogg is it fine if i just select it in Foobar to convert?

Hope this is the right Thread for these kinds of questions, if not just ignore my post

The OggVorbis forums are filled with info, including the Recommended Encoder Versions and Settings thread.

Ogg should give you better quality than MP3 at the same bitrates. AFAIK WMA Standard is inferior to Ogg at similar bitrates too. But you should also consider that different formats can drain different amount of power from the battery...

The lowest which is transparent for your hearing. If you can't distinguish 4 & 6 from the original and 2 doesn't work, use 3 or 4.

If Diskwriter is configured correctly then everything is fine.

You should start your own one in general OggVorbis forum Welcome to HA
