Codecs play an important role in audio streaming, as we have seen in one of my last blogs. I have spent some time to make the Opus Codec available as Arduino Library and I am providing some simple integration from my Arduino Audio Tools library. Opus is a codec for Read more…
As we have seen in my last blog, we will need to use a codec to send and receive the audio data with some proper sampling rate: CD quality e.g. is using 44100. I started to collect some promising low-complexity codecs and converted them to Arduino libraries: sbc lc3 aptx Read more…
Unfortunately the available memory on Microcontrollers is quite restricted and we do not get very far by storing a (uncompressed) WAV file e.g. in program/flesh memory, so I started to look into compressed audio formats. On the desktop we can use the FFmpeg project which comes with a rich set Read more…
