01. #Linux users open your terminal (you must have ffmpeg package installed).
02. Type the following bash command
for i in {100..1000..100}; do ffplay -f lavfi -i "sine=frequency=${i}:duration=0.1" -autoexit -nodisp -loglevel quiet; done
03. Enjoy!
@nixCraft For folks who use fish shell like me:
for i in (seq 100 100 1000); ffplay -f lavfi -i "sine=frequency=$i:duration=0.1" -autoexit -nodisp -loglevel quiet; end;
