encode/decode with Opus
?Hi to everybody.
I have data in a buffer. when i encode it and decode it i does not obtain the same data. i think encode(decode(data)) = decode(encode(data)) = data.
I also try it with trivial example in opus boundle downloded on the official website. My probleme is that how can i write two function myencode and mydecode such as myencode(mydecode(data)) = mydecode(myencode(data)) = data?
Thank

Any luck reproducing the problem with opus_demo or opus-tools?

Oh, if the output is stuck at -32768, then it's likely some NaNs crept
in. The first thing to check is whether the problem is on the

opus 1.2.1 regression with --enable-float-approx and --0fast
Hi,
I work on a webRTC application and recently tried updating from opus 1.1.5
to 1.2.1
Afterwards I noticed occasionally weird audio glitches. I finally tracked
down the issue to the opus decoder in my application outputting samples
with the value of -32768.
This behaviour stopped when reverting to opus 1.1.5 or compiling opus 1.2.1
without configuring --enable-float-aprox and --0fast.

opus 1.2.1 regression with --enable-float-approx and --0fast
Hi Stepan,
I would need more information to be able to investigate further. It's
legal for the decoder to output -32768, so it would be good if you could
explain how this is unexpected. Ideally an audio file with details on
how to reproduce the problem would help.
Optionally, if you could bisect the git repo to see where the problem
started.
Cheers,

You do not need Speex. You do need libogg because .opus files *are* Ogg
files.

There's an easy example called opusenc in the opus-tools package :-)

Now I want to compress interleaved 7 channels pcm/wav ( recorded by Microphone array :6mic+ 1reference signal ) with opus, But I have not found an interface that compress multi-channels pcm/wav.

how to Build .opus file
Hi Toni,
The package you want is opus-tools. You can get it from the download
section. For file distribution, always use opusenc (or equivalent),
never opus_demo.
Cheers,

how to Build .opus file
Thanks for your help, I will follow that, so in order to sum up
I need:
- libopus 1.0.3 compiled as static or shared library
- libogg 1.3.1 compiled as static or shared library
- opus-tools 0.1.7
and then follow the example in opus-tools opusenc.c to get things ready,
because if I try to compile opus-tools, this ask for me for the speex
library, and other things
I think that that will we all.

Hi all:
How do I create opus encoder and decoder executable on Windows using MS Visual Studio 2010?

Encode/Decode problem
I'm trying to use the speex API, and I think I'm missing something. I'm
running on Mac OSX Tiger, and the attached microphone is a iSight. If I
call the "speex_encode_int" function, and then immediately call the
"speex_decode_int" function, shouldn't I get back the same data? i.e.
in my example code, shouldn't the two arrays contain at least similar

help for decode 9-channels opus file
Hi, Dear alls
I had encounted a problem in using opus-tool-0.2-opus-1.3(download from www.opus-codec.org, Win64 binaries: opus-tools-0.2-win64.zip). First, I use opusenc to generate a opus file which input is a 9-channels wav file. The opusenc can work. Then, I use opusdec to transform the generated opus file to wav file, but opusdec can't work. I received the error message: failed to open
