I did a two week artist residency at paradise air (http://paradiseair. Info), in matsudo, chiba, japan. I recorded a lot of sounds in the area, and edited them into a series of thrilling sound effects.
Just the bell without anything else - no keys, no carriage return - just the bell sound. Note: sounds quite bad in your browser because the peak is -1 db. With mpv and vlc it sounded as expected.
