Next Vorbis beta, MPEG+ enkoder
Hi.
When can we expect the next beta version of Vorbis encoder (with some
tagging & encoding options I hope)?
Also, today I tested MPEG+ encoder which you can download from

ABR or CBR?
Just in case my quotation causeed misunderstnaing...
Forget about what I quoted before. Probably, by CBR, Monty meant ABR
since CBR is stupidly patented and this is the reason why Vorbis has
no CBR option. If you know this, it cannot be a problem but I see there
is a question asking what is ABR in the mailing list.

Are two passes useful in CBR mode ?
Hi,
I try to use the video tag to post videos on my blog
I'm using ffmeg2theora to transcode videos in theora
Resolution of 320x240 pixels and constant bitrate (CBR) of ~400 kbps
seems to be ok for publishing on my blog.
I've read that CBR is a better choice than VBR for web publishing
regarding the way TCP/IP works.

oggenc -q switch vs -b switch
Hello folks
I am encoding music to ogg vorbis format for the first time. From what
i have researched, ogg vorbis is natively a vbr format. Also encoding
using the -q switch is encouraged instead of specifying a bitrate
through -b.
Now, while encoding using -b i get this:
Encoding "file.wav" to
"file.ogg"
at approximate bitrate 224 kbps (VBR encoding enabled)

Win32 DLL
I've put together a first cut for a Win32 DLL using the BladeEnc interface.
Right now, it's just a drop-in replacement for BladeEnc.dll that ignores all
encoding parameters passed to it and uses the info_A vorbis_info struct
(same as the encoder_example).
It's not particularly useful as of yet, but you can rename it to
BladeEnc.dll and use it with any number of rippers out there

Speex settings and jitter
Hi Conrad,
Thanks a lot for the info. This is exactly what I needed.
We want to use speex in our IP telephony client and I was indeed trying to
put together
a GUI configuration screen.
Best regards,

OT: OGG in the mainstream
There is a big, big difference between cbr and vbr, btw. The machine in
question is a Pentium 3 700 oc'ed to 800, 512MB ram, win nt 5.1 (2k and xp
being nt) etc
In an earlier version the oddcast dsp ate up so much cpu time when set at
say 64kbps (for examples sake) 44.1kHz, stereo that the machine became
totally unusable and the winamp task had to be (slowly) ended with task
manager.

Should Speex VBR Introduce Distortion?
Hi All,
I've run into a small hiccup in encoding my audios with Speex. When I
encode audience laughter and applause with 'speexenc' (version 1.0.1),
the result is quite acceptable... until I enable VBR. Then it distorts
horribly.
My understanding of VBR is that it frees the encoder to vary the number
of bits emitted to better maintain the quality requested, and so I would
have

vbr / cbr / abr API calls
Hi,
Maybe this is documented somewhere, if so, please send me a link to the
documentation.
My question is: how to set up different (VBR, CBR, ABR) modes when
calling the Ogg Vorbis API?
Currently I do:
CBR:
ret = vorbis_encode_setup_managed( &vorbisInfo,
getInChannel(),
getOutSampleRate(),

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

Comparison between Ogg Vorbis and LAME
Guys (and girls),
I\'ve been testing Ogg Vorbis quality at home, and I thought I\'d share the
results with you. For those who want the conclusion, Vorbis 1.0 RC3 sounds
better than LAME 3.70 vbr/cbr (which I\'m told now that it\'s broken for VBR), at
less bitrate, however, it\'s not perfect (and probably never will, since it\'s a
lossy audio codec) and could use some

Discontinuous encoding and VBR tradeoffs
I'm writing a voice communication application, and I've got a few
issues that I'd like to get ironed out, but I don't know enough about
the speex implementation.
First of all, this application is mainly used for conferencing - many
people are in a room and only 1-2 are ever talking at a time. So,
always encoding and transmitting everyone's audio stream would be
