Zero Noise

Zero Noise is a simple, lightweight multicolor noise generator for sound masking.

I wrote this script to block out background noise like conversations in open office spaces and busy coffee shops.

Features

• Plays various colors of noise: white, pink, or brown
• Built-in timer
• Uses minimal resources
• Wrapper around SoX and Core Audio

Setup

brew bundle

Quickstart

./noise.sh

It is also convenient to add a shell alias such as zn.

Backgrounding

If you background the process normally (C-z), the sound will stop. A workaround is to start it in a tmux session, then background that session to keep the colored noise playing.

Alternatives

Most alternatives focus on generating ambient sounds or noise cocktails whereas Zero Noise is just a simple colored noise generator.
