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 -------------- next part -------------- An HTML attachment...

If you make the same changes and build for a desktop target, does audio round-trip through opus_demo correctly? -r
