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

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
opus_demo -d 8000 1

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

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

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..*.

[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,
Phil Wang

Regarding Opus Codec Input output file.
Hi All,
Need Help !
I am interested testing opus codec encoding decoding qaulity. for this have complied opus code codec from souce. After compiling i got opus_demo app.
for Encoding i followed below steps:
1) Reference file used music_orig.wav (http://www.opus-codec.org/examples/samples/music_orig.wav)
Number of samples : 4358219 (90.8 s) 2015-04-13 10:40:07 UTC

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

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.

[RFC PATCHv1] cover: celt_pitch_xcorr: Introduce ARM neon intrinsics
Hello,
I received feedback from engineers working on NE10 [1] that
it would be better to use NE10 [1] for FFT optimizations for
opus use cases. However, these FFT patches are currently in review
and haven't been integrated into NE10 yet.
While the FFT functions in NE10 are getting baked, I wanted
to optimize the celt_pitch_xcorr (floating point only) and use
it to introduce ARM NEON

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,
