I'm not sure that I understand your goal. In a browser setting, I would think that you want to decode a stream, not a file, because streaming should have less of a memory impact. The reference decoder is a file decoder, so you probably don't want to port that. I don't think that there is a reference streaming decoder, so you'd need to write your own using the libFLAC or libFLAC++

port Opus to Javascript using Emscripten
Hi there,
We are interested in adopting Opus into our web based application for speech recording. I'm wondering if there is a plan to port Opus encoder and decoder to Javascript using Emscripten in the near future?
Best Regards,

How to cross-compile opus-tools?
Hi
Is it possible to cross-compile opus-tools with mingw and Ubuntu?
So far I have done this:-
# prepare
$ mkdir $HOME/source
$ mkdir $HOME/builds
$ export PATH="$PATH:$HOME/mingw-w64-i686/bin"
$ PKG_CONFIG_PATH="$HOME/builds/lib/pkgconfig"
# Install ogg
$ cd $HOME/source
$ svn co http://svn.xiph.org/trunk/ogg
$ cd ogg
$ ./autogen.sh && ./configure

Compiling opus with emscripten: malloc_hook
Hi xiph,
I'm trying to compile libopus from git.xiph.org/opus.git with
emscripten. The regular:
$ emconfigure ./configure --enable-fixed-point
$ emmake make
gets me quite far, but it hangs on the use of __malloc_hook in the tests:
tests/test_opus_api.c:1776:16: error: use of undeclared identifier
'__malloc_hook'; did you mean 'malloc_hook'?
orig_malloc=__malloc_hook;

Antw: [opus-tools] [PATCH] Add channel-mapping argument to force channel mapping
Hi!
I haven't looked into the code yet, but the patch uses different coding conventions like "if(" and "if ("; like wise "){" and ") {". My personal taste is to have spaces after keywords, but that's just me.
I'd prefer a consistent coding style.

Problem compiling opus-tools-0.1.7
Hi,
Seems like it's not linking with libm. I suspect it has to do with
linking statically with libopus.a (is that intended?). Maybe opus-tools
relies on the fact that libopus is linked with libm and doesn't
explicitly add it? Greg?

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

library for creating Opus files?
Hello Tony,
opusenc from opus-tools works for me.. Just tried it successfully on
my x86_64 Ubuntu Trusty 14.04 box.
I was just able to do
$ sudo apt-get install opus-tools
$ opusenc music_48kbps.wav music_48kbps.opus
I remember also being able to compile opus-tools
(git://git.xiph.org/opus-tools.git) some time ago.

High Frequency Hiss with Opus at 48 kbit/s
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi to everybody.
First of all I hope this is the right place to discuss such an
(nitpicky) issue.
I've just been testing the current Opus release and for mere curiosity
compared its performance to WMAPro with CD quality music at low
bitrates (48 kbit/s).
While Opus generally does a very good job, I found one particular
example (a high pitched

Yeah, de-/encoding a stream would have a lot of advantages but there is no streaming en-/ decoder I would be aware of and for the application I'd intend to use it for, it might be sufficient to de-/ encode a file in whole. Dependent of the time and efforts for creation and maintenance of a stream encoder, it might not fit into the time budget. (Apart from that, as of now, it gives a nice demo

opus Digest, Vol 121, Issue 3
1. For starters, 32 bit support is deprecated in the next version of Mac
OS X. Other things like Hardened Runtime (
https://lapcatsoftware.com/articles/hardened-runtime-sandboxing.html) may
not be relevant, but to make things compatible, apps need to be compiled
with an SDK > 10.7. The 64 bit is the big thing.
2 & 3. I want static and can't figure out how to get it to compile. Why

DSPs which are suitable for porting OPUS
Dear Christian van Bijleveld,
You can use any of the below DSPs of Texas Instruments
1. TMS320C674x - This supports floating point implementation of opus
2. TMS320C66x - This supports both floating and fixed point implementations
3. TMS320C64x - This supports only fixed point implementation

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.

Linux opus-tools static builds.
Hi
Some Linux programs are 'static'.
For example, these FFmpegs here ---> http://ffmpeg.gusari.org/static/
If we compile with Linux
opusdec & opusenc & opusinfo & opusrtp
using only static libraries
libogg.a & libflac.a & libopus.a
Are the four opus-tools programs then genuinely 'static', so that they will work on *any* Linux OS?
$ ./opusenc -V

AM335x ARM Cortex-A8 performance drop opus 1.1
Hi,
Just to clear things up... So 1.1 has some new analysis code that
increases the amount of CPU. When building as floating point (which you
appear to be doing, right?), the new code is enabled at complexity 7 and
up (opusenc defaults to complexity 10 IIRC). This is why you've been
seeing an increase in the CPU time. In version 1.0.x, complexity 5-10
are the exactly the same for music.

Problem compiling opus-tools-0.1.7
Hi
I'm having a problem compiling opus-tools-0.1.7.
Version opus-tools-0.1.6 seems to compile OK.
I've tried with opus-1.0.3 and opus-1.1-beta.
The errors are like this:-
"undefined reference to `sqrtf'" etc.
This OS is Peppermint Three, similar to Ubuntu 12.04.
It uses:-
gcc --version
gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3
Google says it's maybe something to do
