Visual Studio Project file?
I am working on a project that transports audio in realtime from a linux
box to a windows box throuh libcelt.
The windows client program is written in C# and C++ and I therefore need
the celt library in its most recent version (0.7) to be able to compile
in Visual Studio 2008.
In order to do this I, as I understand it, need a .vcproj file for the
project.
Are there any plans on making such a

Phase perservation in Opus
Hi list
I'm writing some unit tests for a piece of software using the opus
library for audio encoding before transfering though RTP.
In order to test my RTP implementation I thought I would transfer an
encoded 440Hz sinus, and then do a diff of the received/decoded signal.
However, my strategy seems to fail completely since the recreated sinus
looks nothing like the one in the decoded

Stereo dropping to mono with libopus 1.2 RC
Hi Matěj,
I had a look at your files and it seems like the issue is that the
speech/music detector thinks that some segments are speech rather than
music and at low bitrates SILK tends to significantly narrow the stereo
image. We're planning on adding an option to opusenc to force it to
treat the input as speech/music. Just to confirm that's the issue, can
you try encoding with the

Stereo dropping to mono with libopus 1.2 RC
Hello, I'm not a programmer or Opus developer but I tried to test the sound
quality of a music file (Nick Warren - Devil's Elbow, freely available from
the author's Soundcloud account) encoded with libopus 1.2 RC1. I used
Windows binaries from free-codecs.com. I noticed that in the case of my
selected music file (which is generally harsh on lossy codecs as it's
necessary to

Stereo dropping to mono with libopus 1.2 RC
Hello Jean-Marc, yes, it works for both 32 and 48 kb/s. Also this option
marginally increases the size of the file which is understandable. I tried a
few other music files and found that this stereo narrowing happens not only
in the case of track I submitted (although in smaller scale) so it would be
great if the final libopus 1.2 had officialy a parameter to force music

Opus 1.1-rc is out
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
We just released Opus 1.1-rc, which should be the last step before the
final 1.1 release. Compared to 1.1-beta, this new release further
improves surround encoding quality. It also includes better tuning of
surround and stereo for lower bitrates. The complexity has been
reduced on all CPUs, but especially ARM, which now has Neon assembly

opus_multistream_encode_float not working in libopus 1.1
I just recently found that opus_multistream_encode_float is returning
-1 (OPUS_BAD_ARG) with the libopus 1.1 build but works just fine with
the libopus 1.0.1 and libopus 1.1-beta builds. I tried using
opus_multistream_encoder_create and
opus_multistream_surround_encoder_create. Tried with coupled and
uncoupled quadraphonic and uncoupled stereo encodes. I'm dynamically

libopus API question - 120ms encoding

Just one 20 ms frame. It always returns a single frame except when it
just can't (e.g. 60 ms CELT).

libopus API question - 120ms encoding
Thanks Jean-Marc and Benjamin for the answers.
One follow-up question. If I use a repacketizer as Jean-Marc suggested by combining two 60ms frames to form a 120ms frame, without extracting individual frames and using a new TOC, I would need to have a "de-packetizer" that does the exact opposite of repacketizer. De-packetizer would need to separate this 120ms frame into two 60ms frames

libopus API question - 120ms encoding
The libopus encoder's opus_encode() method is documented as "Encodes an Opus frame". Does that mean that it always produces a single Opus frame (i.e. the number of frames in the TOC byte will always be 0)? It's not clear from the documentation, but the fact that it cannot produce a 120ms Opus packet makes me wonder if that was the intention and any multi-frame Opus packets must

"Official" libopus project for Android?
I was digging around and saw a bunch of different people have created
ways of building libopus for android (even I did one back in the CELT
days). Is there an official one somewhere that I missed?
I even notice this is the Google sources, but it seems to be a touch
long in tooth at this point:

Conformance testing of libopus in encoding mode
Hi,
I'm working on porting libopus to some specific platforms. Due to some restrictions of the platform and to improve the performance I had to change a bit the accuracy of some functions (fft, mdct and so on).
With a help of tools provided with the source code, I can check that my changes in the code are not the cause of serious damages during decoding, and all decoding tests are passed.

Understanding libopus parameters
Hi,
I'm looking for the description of possible combinations of libopus parameters. For instance in case of low bitrate encoding (voip application, SILK part) it does not have sense to set 2 channels. Audio applications (CELT part) widely use 2 channels.
What about HYBRID mode? Is it closer to voip or audio applications? What is the typical number of channels? Can constant bitrate be used in

libopus build environment assistance request
Folks,
I am having difficulty building libopus from source and am in need of
assistance. The reported error shown below appears to indicate the

variables without success. An exhaustive web search has not

You're right. Doesn't work on the libopus-1.1 source tarball. Sorry
