Regarding Opus Codec Input output file.
Hi Sakharam,
I see 2 potential issues with what you are doing.
1. ./opus_demo -e voip 48000 2 16 music_orig.wav testcase30.opus
in above command, "16" for bits/sec seems too low. I'm no audio
expert, but just cant convince myself you can get any reasonable audio
data with 16 bits/sec. FYI, I was able to encode and decode with 16
bits/sec, but when I played the decode file with

inbandfec is adding samples
I didn't expect this, is it normal? When you use inbandfec, and have packet losses, you end up with more audio samples than you started with.
With short frame (2.5), the FEC isn't supposed to do anything but it shouldn't do that should it? and 20mS frame, should do 'something' but? add audio?
I'm using opus_demo for this.
Here's the steps (I have my test audio in

AM335x ARM Cortex-A8 performance drop opus 1.1
Hello!,
i've just compared the 1.0.3 release with the master branch
on a BeagleBone Black (AM335x 1GHz ARM Cortex-A8 with NEON
floating-point accelerator) and Arch Linux ARM.
At the moment I dont no why, but I see that 1.1 is much slower
in encoding. Are there any default changes, that I missed and could
explain this? Normaly I suggested a better performance with 1.1 and

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.

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

OPUS encoding mono sine wave
I wonder if anybody try to compress a pure sine wave using OPUS codec.
When I compressed the mono 1KHz, 16bits 48000 samples per sec. audio stream using the 'opus_demo' utility:
opus_demo -e audio 48000 1 2min_1kHz_Sine_16bit_48kHz.wave 2min_1kHz_Sine_16bit_48kHz.opus_raw
I had the output stream that is shown below.
00 00 00 01 00 00 00 00 78 00 00 00 01 00 00 00 00 78 00 00 00 01 00

help with opus_demo
Hi
I used opus_demo to clarify how opus works, I try this command:
opus_demo -e" audio 8000 1 8000 -cbr /somedirectory/pcm_mono_ochomil.raw
/somedirectory/test.opus
And I get the file test.opus, then comes the first problem, this file
hasn't header so i can't reproduce it using an external tool, how can i add
a header to this file
Then when i trie to run

Quality difference between opus_demo.exe and opusenc.exe
Hello!
I encoded a voice file (48kHz) with opusbin\opusenc.exe with the
standard settings and decoded it.
The output was amazing. I could not hear any loss at all.
Then i encoded the same file with opus_demo.exe and standard settings
and then decoded it.
The output had a sizzling noise, even when I used full bandwidth.
I think I have played around with any of the settings in opus_demo.exe,

Availability of the 1.1.1 stable version
Hi,
There is no change in the compiler flags. I'm using as it is from the
original code. No change in the Makefile and I believe it is using the
floating point only by default.
We are using 8k samples and mono so the commands is as follows.
[root at MEDIA opus-1.1]# ./opus_demo -d 8000 1 opus_encoded_crash.opus
opus_encoded_crash.pcm
*And segmentation is as below..*.

Opus DTX issue report
Hello:
We noticed that opus reconstructed noise is pulsing with a 400ms pattern when dtx is enabled in silk mode. This is independent of the background noise level and is found with speech + non-speech period test files as well as variable level noise-only test files. This issue can be reproduced with opus v1.1 using this command:
./opus_demo voip 16000 1 25000 -dtx input.bin

how to Build .opus file
Hi Jean
The problem is that for using this package I need to use all the libs like
ogg, even Speex?, no, and also where i can find an easy example like
opus_demo.c to create the .opus file

Availability of the 1.1.1 stable version
To be decodable by opus_demo, you'll have to add the 8-byte "header".
Just put in the length of the packet followed by "0" for the encoder
range (0 means "not present").
That being said, from previous experience, the most likely cause of the
crash is a bug in your software causing a corruption in Opus. So it's
safe to assume that if you can't reproduce

how to Build .opus file
Hi all!
Using the code in opus_demo.c I write a c program for encode and decode the
audio from one microphone, I can encode and decode raw audio into .opus
file, but really is not an opus file because i need to add the "OpusHead"
and the "OpusTags". In order that any opus player can play that file.
So I only need in my c program how to add this streams to my file an how to

Availability of the 1.1.1 stable version
Hi,
We are able to reproduce the issue with the 1.1 opus_demo (sample file). We
captured the frames in our server just before the opus_decode and fed the
file to opus_demo (1.1) and it is crashing. Same file is tested with 1.1.1
and it is fine. So this is in line with our server testing observation and
I think here we can conclude that the 1.1 library is crashing while
handling a specific mode
