Wow that is so cool! Will ffmpeg generate ultrasound sounds to, or do we know of a plugin or other that could do that, then feed the signal to ffmpeg?
Sure, you can generate ultrasound with FFmpeg. Try the first example in chapter 3.24. Of course, the frequency must be smaller than half the sample rate. Make a 12kHz sine file and then try to convert it down to 2kHz.
