Just tried to encode a 5.1 file (6 channels in F2K) [Dances With Wolves Speech Sample (DTS Master) 48Khz], -q4 I get 331Kbps (128x5/2=320Kbps expected) & quality seems ok (Didn't ABX)
So personnaly I cannot reproduce the bug (Doesn't mean there isn't any).

Edit:
I used john33's oggenc2 like capma, not venc like alter4.

I don't know if the BS (Block-Switching) issue has been addressed in this latest Beta v601 release, but I can still easily ABX the Autechre killer sample.

The fact that such a bad sample for vorbis is still easyly ABXable is not really a surprise IMHO (unless you expect miracles like aotuv b2 at each aotuv release), the real question is more: is there any improvement even if still ABXable.

Could you change your oggenc2's writing library in OGG COMMENT?

oggenc2(yours)
AO; aoTuV [20110223] (based on Xiph.Org's libVorbis)

venc
AO; aoTuV [20110223] (based on Xiph.Org's libVorbis)

I wanna diplay your oggenc2 for aotuv
like this

Are you saying that you want the 'AO: ' removed from the front of the Vendor String? If so, I'm not sure that I should considering Aoyumi created the modified libraries and that is his chosen Vendor String. To change it might suggest that I am using a different version of the libraries.


I wish to read from OGG COMMENT as TAG in writing library by Encoder at (or)Foobar
Im not talking bout BSD or ect
Well.i gave up it
Thanks jonn33

@sauvage78

01- DCT Killer Samples (Lossless)\01- Artefact+Context\02- Autechre (Artefact+Context) Lossless.flac
01- DCT Killer Samples (Lossless)\01- Artefact+Context\03- Castanets (Artefact+Context) Lossless.flac
01- DCT Killer Samples (Lossless)\01- Artefact+Context\04- Harlem (Artefact+Context) Lossless.flac
01- DCT Killer Samples (Lossless)\01- Artefact+Context\05- Kraftwerk (Artefact+Context) Lossless.flac
01- DCT Killer Samples (Lossless)\01- Artefact+Context\06- Rush (Artefact+Context) Lossless.flac
01___Pet_Shop_Boys___In_The_Night___cutted.flac
bibilolo.flac
emese.flac
Linchpin__Edit_.flac
Replica._Lossy.flac

So thanks Aoyumi for the splendid work.

@OggY68

Did the bitrate increase a lot for these samples (compared to previous aoTuV) ?

Hi ALL.

I am Back with 6ch encoding problems. The problem is sample(or maybe format) specific.
There is a one of problematic 6ch file.
Download sample and try to encode using aotuv beta6.01 to catch the bug.

Thx and hope somebody helps to fix.

P.S. HA! looks I find the problem! aotuv can't properly encode 44100 rate 6ch files, but can 48000 rate! Please confirm!

Confirmed. Resampled file (to 48000) encodes correctly.

It is clear now. The question is closed, new bug report is open.

P.S. But the good news are 32000hz 6ch files convert properly as well, so I think it something like "slip of the pen" in aotuv code, and Aoyumi (if hi has free time and good opportunity smile.gif ) can easily fix it.

About 5.1ch
I recognize the problem.
There are some causes, and time is necessary in investigation and a revision.
Sorry.

OK. I think this bug is not critical, not all guys rip 6ch music from movies to ogg:)
But just for sure Aoyumi could I ask you? Will you profile fix ...as ready... or postpone the fix for a long term?

Sorry again if you feel me tactless.

I want to release fixed version in the time early as possible.
But I cannot yet declare it about the time...

Hello lvqcl,

thank you for your tests.

I think, number 2 is OK, and number 3 is not OK.

What is with number 4? Is it OK? There is some schlieren between the lines.

I think, the original is 44,1kHz. Have you tested 48kHz, too? This is the common sample rate for digital TV (DVB).

Best regards

I cannot see or hear problems with this sample resampled to 48kHz.

Numbers 3 and 4 aren't not OK IMHO (ABXed 8/8).

Thank you for a report.

If the problem that you recognize produces even "libvorbis 1.3.2", I understand the problem.
I intend to try the improvement of the problem in the future.

Oops. Sorry that I didn't this before. Yes, libvorbis 1.3.2 also shows similar problems with 88 and 96kHz, but in other places of the track.

Hello Aoyumi,

is everything OK with you? In your user profile is written, that you are living in Kanto. And I saw, that Kanto is near Fukushima.

My best wishes to you, to your family and the whole Japanese nation.

Best regards

These types of messages should be done via PM, please read TOS #5 if you have any questions.

That said, my heart goes out to all those affected and to be affected by the catastrophe in Japan.
