Hi,
I searched the Audacity Site for that, but could not find that topic. Someone wrote that Audacity can do that. If so - how?
Thanks for your hints!
Top menu bar > Generate. You can make tones, drums, metronomes, etc.

If the basic native tone generators are not doing it for you, there are plugins which generate more complex sounds, see … https://forum.audacityteam.org/t/expression-generator/45227/1
Sorry, my quest lacked precision: I am looking for 20-100 Hz e.g. sinus, rectangular waves, (white) noise, or simply “wall vibrating” noise, probably in a low Hertz range. That file will be saved on a CD and played on a simple CD player.
I tried to delete my newest post, because I overlooked your post, not possible. Probably mentioned tone generator will do the job, thanks!
