encoder configuration
Hi,
How can I force encoder to create stereo?
OPUS_SER_FORCE_CHANNELS only works for mono
How can I force encoder to encode at a specific bandwidth?
OPUS_SER_BANDWIDTH only works for FB (1105), and the encoder
Seems to encode at the input samples rate, no rate conversion is done
Thanks,
Michal

Vorbis encoding at half speed
Echoing Hiroka, who is likely on the right track.
Simply telling the encoder 'one channel' and then passing stereo data
will not convert the stereo data to mono. The encoder encodes
whatever it is given...

Standard encoding rates?
Is there a list somewhere of "standard" encoding rates? I know, for example,
CDs are encoded at 44100, as is a lot of digital sound, but I've seen
programs that specify different levels of quality (like radio, phone, tape,
CD) and I'd like to know if there are some encoding rates that are accepted
as standardized for recording at different levels of quality.
If so, is there

Vorbis encoding at half speed
I’m using a Windows development component which uses vorbis.dll, ogg.dll, vorbisenc.dll for encoding an Ogg Vorbis file. It's all working well except for one user occasionally has a 1 hour file appear as 2 hours and it plays at half speed. It is being converted from stereo to mono before feeding the encoder with a channels=1 configuration.
Here is an example file which will be available for

Realtime encoding at 44.1khz
Hi:
I've been experimenting with streaming vorbis across my network from the
windows box to an icecast2 server on my linux machine (the server I usually
use is having some network issues at present). I've tested both ostream
0.7.1 and oddcast beta26. It seems that neither can encode on the fly on
my P2-266 at 44100 fast enough to be able to stream it. Ostream looked the
more promising

Force Opus/CELT to encode 2 mono instead of 1 stereo
Hi, folks,
I have an old CELT thing that I'm updating to Opus and I'm trying to get
individual pieces upgraded. My first task is upgrading the CELT encoder
to Opus.
The old CELT thing treated the L and R channels as independent mono
streams, encoded them somehow with CELT to form one bitstream, sent one
bitstream across, and then unpacked it manually after the decoder.
Can I do that

Force mono encoding of a stereo file
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello
For some reasons, I need to encode in mono a stereo wave file, as with
the --downmix option from oggenc.
I searched in speexenc man page and in the on line documentation,
unsuccessfully. Of course I could first use something like sox to down
mix my file, but it would be more practical to have an option directly
in speexenc.

Just a minor nit-pick: AM radio can be stereo. However its use is almost
nonexistent. See <http://users.hfx.eastlink.ca/~amstereo/amstereo.htm>
for more information.

Encoding audio sampled at 44.1 khz?
Hi everyone,
I recently began using libspeex 1.2 Beta 1 on Windows using MS Visual C++. I have gotten a decoder and an encoder to work fine from the excellent sample code posted at the website.
But I face a problem. I am working on using Speex in a program to play and create audio books encoded using Speex (currently testing it only; for these tests, I do not use Ogg to save the encoded

advantage of OPUS_SET_FORCE_CHANNELS(1)?
I'm using Opus for a networked ham radio communications receiver. Kudos
on the whole project; it sounds excellent even at low bit rates and the
API was surprisingly simple and easy to use. And god knows the world
needs a really good, general purpose, non-proprietary codec.
One question, though. Depending on the mode my receiver can generate
mono or stereo. Most operating modes are mono, but a

Is it possible to record 2-4 party call audio in stereo quality as opposed to mono?
We have a customer who wants us to record anywhere from 2-4 participants on a call in stereo (as opposed to mono) quality audio.
Some background..
We are using asterisk 16.6.1
We are also currently using AMI/AsyncAGI and ConfBridge to bring the parties together. I believe recording in the various file formats (based on extension), it's always recording in mono quality.
My one thought is to

Simple OGG editing without re-encoding?
I have some OGG files which would benefit from the following
simple corrections:
a) removing left channel (which is empty) and changing right
channel to the mono channel (mono sound stereo-recorded by
mistake)
b) volume change
Of course I can open the files in audacity and do those
corrections but that would require re-encoding. And I am afraid
that it will result in additional loss of the

encoding 22 kHz
hi,
is it possible to encode 16 bit, 22 kHz, stereo/mono WAV files to FLAC files
or could there be a problem with the low frequency 22 kHz (lower then CD
quality)?
PS: I'm a FLAC beginner
thx
