vorbisenc API docs
Hi, I'm trying repeatedly to get some more information on the vorbis encoding API. My last questions on this list were regarding vorbis_encode_ctl(). Of course prior to posting such questions to the list, I checked the vorbis web site for info. Unfortunately there is no information on the related function, the page http://www.xiph.org/ogg/vorbis/doc/vorbisenc/vorbis_encode_ctl.html merely says: not yet implemented (even though it is). A...

Cannot disable stereo coupling
...encoding.<br> <br> On the web documentation (<a href="http://www.xiph.org/vorbis/doc/vorbisenc/overview.html">http://www.xiph.org/vorbis/doc/vorbisenc/overview.html</a>), i read : "Stereo coupling my be disabled <font color="#000000">by using vorbis_encode_ctl() with OV_ECTL_COUPLE_SET.". But the constant "OV_ECTL_COUPLE_SET" doesn't exist in vorbis files... and in the vorbis_encode_ctl() func</font>tion, there are no code to disable coupling stereo...<br> How can i disable stereo coupling ?<br> <br> Thanks.

How do you set the encoder bit reservoir size?
Hi; In the Vorbis 1.1 release notes from July 7, 2004, Monty says "The 1.1 libvorbisenc allows setting the fixed reservoir size (in bits, defaulting to two seconds worth of requested bitrate) and 'hoarding' behavior (whether the encoder tends to keep the bit reservoir more full or more empty) as well as the other encoding heuristics available through the API of 1.0.1."

Uncoupled mode?
Hello, A question: Can we use uncoupled encoding in the 1.0? (current CVS) How? Because I see some uncoupled definitions (books\uncoupled\res_books_uncoupled.h), but I don't know how could I switch to it manually. Perhaps with an option in the vorbis_encode_ctl() function... Because I think so it's better if I don't use any kind of channel coupling (lossless neither) on high bitrates (>300 kbit). Plans? Solutions? thanks Attila Padar <p><p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepag...

ARG! I FIXED MY BUG!
Hello, well, I've been chasing down a stupid bug for two days... Okay.. so I know it's my fault for not fully reading the libvorbisfile documentation, but it would be nice if in the example decode source (on the www site) for it to say next to the "ov_clear(&vf)" call that " /* and this also closes the file */ "... I knew it was a heap corruption bug, but

problem with encoding cbr (updated)
Hi, Regarding to my previous question, I think I have found out from oggenc source code that the correct way to initialize encoding is: vorbis_encode_init_vbr (or vorbis_encode_setup_managed for cbr etc.) vorbis_encode_ctl (to turn off or use avg bitrate management) vorbis_encode_setup_init By this way, there is no problem with encoded stream. However, there is no documentation of the three function above (except vorbis_encode_init_vbr) on the cvs snapshot of vorbis. Thanks... Mete ----- Original Message -----...

vorbis API calls
Hi devs, I am developing winLAME, a frontend for LAME, and it also supports Ogg Vorbis decoding and encoding. I've got a question about the new API function vorbis_encode_init_vbr(). Do I have to call vorbis_encode_init() before to set the bitrate(s)? And what is a good default value for the "base_quality" parameter? I read on the mailing list that ABR use in Ogg Vorbis is not so

PlusV algorithm
Important (imho)! I found this site in the internet: http://www.plusv.org/ PlusV is an audio enhancement algorithm similar to SRB of Mp3Pro, but 1) better than SBR 2) Fully open-source It seems to me wise to include PlusV into new versions of Ogg Vorbis. P.S. what about some long-awaited features in Ogg Vorbis? 1) ability to turn off the frequency filter in the encoder (especially for high

confusing comment in encoder_example.c
I think the example in the comment has a '-' that shouldn't be there (line 108): /********************************************************************* Encoding using a VBR quality mode.

5.1 surround channel coupling
>Yesterday I have finished writing the ambisonic pan filter for oggenc. May I ask what this "pan filter" is? I made some tentative suggestions for coupling Ambisonic B-format in a post "Vorbis Ambisonic coupling" on 4feb07 I gather from the last monthly meeting, that some of you, including Monty, had problems with the phase behaviour of B-format.
