...the speaker - there was an one bit offset between FS signal and sound slots, which I didn't take into account. Now I have the clear enough sound with 30% MCU load for full duplex sound. 2016-07-12 20:46 GMT+03:00 Ralph Giles <giles at thaumas.net>: > On 2016-07-12 9:34 AM, Aleksandr Mikoff wrote: > > > If I encode each frame, decode it and send it back to the speakers I > > hear a very noisy signal - it is so large, so it is almost impossible to > > distinguish words in my speech... > > This effect can be caused by some data type issues: > > - If you...

Hello everyone. I have a problem with a high level of noise after opus encoding/decoding procedure. If I stream a raw data from the microphone and send it back to the speakers I hear the clear sound (with a small delay). If I encode each frame, decode it and send it back to the speakers I hear a very noisy signal - it is so large, so it is almost impossible to distinguish words in my speech...

Hello everyone. I would like to use the opus codec in the following scenario: the PCM audio signal, coming from bluetooth module is captured by STM32F446 MCU and then decoded by opus codec. However, I don't know where to start to build the opuslib for ARM Cortex-M4. Could someone provide any hints or give any brief guide on this?

This effect can be caused by some data type issues: - If you are using opus_encode() and opus_dec...
