   Hi @acassis , I belive it works on other boards supporting audio, because no spresense specific code in it. But I didn't test it on them because I don't have. At least I did unit test on linux (those code is in this PR in audioutils/fmsynth/test) and it works well.
   
   fmsynth is just making audio samples. So even if the board has no audio function, it works.
   nxaudio is an utility library for nuttx audio driver. So every boards supporting audio can works.
   
   But, I dare say, it is depending on cpu performance. fmsynth is calculating every single sample. (It is the reason that I didn't use sinf() function of regular math library.)
