- Create a new
aiff
audio file in GarageBand about a second long, "Share"->"Export..."->"Save as silence.aif"
- Easier, download the audio file I created: https://github.com/todgru/dotfiles/raw/master/silence.aif
- Save audio file to
~/Library/Sounds
. - Open "System Settings" application.
- In "Sounds", Select "silence" from drop down list(see screenshot).
Enjoy the silence. 😎
