inbandfec is adding samples
...39;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 it's own folder, parallel with opus and sox):
make raw audio:
../sox-14.4.1/sox music_orig.wav -t raw music_orig.raw
try a few different encodings:
../opus-1.1-alpha/opus_demo audio 48000 2 128000 -framesize 2.5 -loss 10 -inbandfec music_orig.raw music_orig_f2.5_b128000_lr10_fec.raw
../opus-1.1-alpha/opus_demo audio 48000 2 128000 -framesize 2.5 -loss 10 music_orig.raw music_orig_f2....

AM335x ARM Cortex-A8 performance drop opus 1.1
....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
the ARM optimizations.
Please let me know, if you need more informations.
opus-tools version 0.1.7

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
Sampling frequency: 48000 Hz
Number of channels: 2 (16-bit integer)

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 "apl...
