We’ve seen little DIY volume knobs before, and they’re a handy way to add means to finely adjust the volume on your computer. Instructables user Trochilidesign’s made their own, and it’s pretty futuristic looking.
Android: You’re in a quiet place, you get a phone call and a loud ring roars out of your phone. Volume Scheduler is a free app that can help you out when you’ve forgotten to silence your phone or set it to vibrate.
Mac: Not all apps have the same base volume, and sometimes one app likes to really scream at you while another is too soft. Volume Mixer allows you to independently control the volume of apps.
