High noise after encoding/decoding procedure
...s almost impossible to
distinguish words in my speech...
Should I preprocess the raw pcm data somehow before feeding it to the opus?
Is it ok, that I changed few parameters in "defines.h" file (to suppress
the RAM requirements - I have only 60 KB RAM free on my STM32 board)? I
changed the ENCODER_NUM_CHANNELS 1 and DECODER_NUM_CHANNELS to one,
and MAX_FS_KHZ to 8.
In the code I forced the codec to use SILK mode and to have only one
channel.
I would be happy for any feedback - where to start and what to check the
first.
Thanks!
WBR,
Aleksandr

- Make sure you're passing the size of the compressed opus data in _bytes_.

That's not a tested configuration, so it's possible this broke
something. If you make the same changes and build for a desktop target,
does audio round-trip through opus_demo correctly?
