OS X opusenc/opusdec?
Hi,
I've been using the command line opusenc/opusdec tools for a while now to
encode/decode files. The next version of OS X changes a few things, so I
was looking to recompile these tools using a version of the OS X SDK > 10.7
(needed for apple's "hardened runtime") but had no luck.
How can I compile a static version of opus tools on OS X that doesn't
depend on any other

OSS DSP sound card input on CentOS 6.2?
Hello everyone,
I'm streaming audio on CentOS 5.8 with no problem, even on a cheap sound
card using DarkIce as the input tool. For the input under CentOS5, I use:
device = /dev/dsp # OSS DSP soundcard device for the audio input
But under CentOS 6.2, there is no such device. I see /dev/snd, and it
has:
controlC0 hwC0D2 midiC0D1 pcmC0D0p pcmC0D2p pcmC1D0p seq
controlC1 hwC1D0

Sound drop out with totem. mplayer Can't open audio device /dev/dsp
Hey all.
This morning I found that my audio playback is randomly sprinkled with
sound skips and dropouts. I went to /var/log/yum.log and found this:
Feb 09 20:18:22 Updated: lame-3.99.4-2.el6.rf.i686
I'm not saying that caused the problem but it's all I could find that
changed.
When I ls in /dev there is no dsp entry.
That would explain why mplayer Can't open audio device

Opus files don't have a sampling rate anymore; the internal
representation is most efficiently decoded to 48kHz.
The metadata records the original sampling rate which make it possible

No Sound in Wine - disable / remove pulseaudio
Wine requires direct access to sound device(s) to make sound. This is true for both ALSA and OSS driver back-ends. However most sound servers are not compatible with neither of these back-ends. This also true about pulse-audio - it is not fully compatible with Wine.
If you using new distro (Fedora 8, Ubuntu 8.04, SuSE 11) and do not have sound you should:

pulseaudio wine
Hi. I can confirm that pulse does indeed work quite well with wine. I've been using oss emulation and padsp together for a long time now, and I've had very few if any problems with it.
I simply use
Code:
aoss padsp wine
whatever and it's fine. I don't know if I need to use padsp after aoss after reading this thread, but it's what I've been doing. So pulse does mostly

[Profiling][FFT][AArch64] FFT Profiling data on AArch64
Hi everyone,
I have profiled Opus on AArch64. I just run opus_demo with some pcm files.
Following is time proportion of FFT with different bitrate.
Bitrate | Time cost by FFT/iFFT
24kb/s | 15%
48kb/s | 15%
96kb/s | 13%
Any comment? I want some data close to real application, any suggestion?
Thanks,

[SUGGESTION] WINE, autodisable/ask to disable PulseAudio
Since PulseAudio causes much trouble alot, why not make WINE to either
1) autodisable
2) ask to disablePulseAudio when running something ?
By my understanding if this would be implemented, either of the following is done:
1) When executing wine theprogramname.exe it first calls to WINE, which then query the system for PA. Then if PA is found, WINE adds padsp to the commandline and continues

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

Stereo voice not being retained
Hello,
I've been using Opus on an STM32 M4 platform for speech coding in mono mode. I thought I'd try stereo for grins to see if I can handle the CPU load, and I'm getting a return code of -1 from opus_decode_float (using CBR and 40ms frames).
I decided to try the opusenc and opusdec tools to just see how the command line apps would behave. I am getting decoded audio, but I am

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

quality opus_demo vs opusenc
Hi,
I have found differences in quality between opus_demo and opusenc/opusdec.
I used for both applications the same raw pcm file,16 bit,48khz,litle
endian. i use libopus 1.1-beta and opus-tools-0.1.7.
The command for opus_demo is:
opus_demo audio 48000 1 64000 -cvbr -framesize 10 in.pcm out.pcm
For opusenc/dec:
opusenc --raw --raw-chan 1 bitrate 64 -cvbr --framesize 10 in.pcm in.opus

What sine sweep exactly? How did you obtain it,
and how exactly did you encode and decode it?

Opus in Audacity
Hi
I am an Audacity (http://audacity.sourceforge.net/) developer and I'd
like to see Audacity reading and writing Opus files as easily as it
does others. What would you recommend as a way forward for this?
I am thinking that (Win) we should ship opusenc.exe and opusdec.exe
and send command line stuff to them; that way we wouldn't need to dip
into your code and as you update we would

When I install the current version of opus-tools on my Ubuntu system, I have the following problem:
When I try to open the test vector 'testvector01.bit', I got the error message 'Decoding complete. This doesn't look like a Opus file'.
When I open the 'testvector01.bit.opus' the decoding works fine, but the tool opus_compare mentioned, that the number of
