At this moment fails on ARM Cortex-A53 and Cortex-A55, works on RISC-V 64. wget https://downloads.xiph.org/releases/opus/opus-1.5.1.tar.gz tar -xf opus-1.5.1.tar.gz cd opus-1.5.1 sudo apt install autoconf automake libtool gcc make ./configure sudo make install This version brings non-marginal improvements for spoken content at low bitrate.

IngwiePhoenix, you are welcome!

I wanted to ask you why the RISC-V images are missing and in particular in one case the previous ones are also missing, e.g. https://imola.armbian.com/archive/mangopi-mq/archive

The RNNoise code and instructions for compiling it are located at https://gitlab.xiph.org/xiph/rnnoise and highlight the latest addition of Jean-Marc Valin, a developer who I can never thank enough for the work he has done. Two years have passed since the highlighted addition and therefore updated instructions on how to complete the compilation would be useful in general and not just for the hardware we have. This is the sequence of commands: sudo atp update sudo apt install autogen sudo apt install configure-debian sudo apt install dh-autoreconf ./autogen.sh ./configure make -j36 sudo make install -j36 You will now have the RNNoise libraries installed on your system and the demo program to try them in the examples folder. RNNoise is an audio noise suppression library based on a recurrent neural network and it cannot be missing on the hardware used to record the human voice. Those who don’t know it yet can find the documentation on Archiv website and further information on the Mozilla and Jean-Marc Valin's website. I’m sure someone will appreciate it.
