Hi Palmu, For the extracted data; I would just output the binary data in a such way > that it ends up in pulseview decoder binary view > this is exactly what I would like to achieve

Then in addition to audio processing software it may be possible to use software such as Octave or Matlab best regards On Sun, May 7, 2023 at 10:37 AM Vesa-Pekka Palmu <vpa...@depili.fi> wrote: > Put the decoder in a some git repository and post the link in here. > Currently we are lacking code reviewers, so it would also help if someone > else could go and take a look at the code.
