A Soft Murmur
Ambient sound mixer for the browser, iPhone and Android
What is A Soft Murmur?
A Soft Murmur is a background noise generator that runs in the browser, with companion apps for iPhone, iPad and Android. Each ambient sound, such as rain, thunder, waves, wind or a coffee shop, has its own volume slider, and the resulting mix can be saved, named and shared. The website is free with ten sounds, and a yearly Pro license adds more.
A Soft Murmur has a free plan. Paid plans start at $14.99 / year (Pro, bought on the web); iOS sound packs are $1.99 to $3.99 each. See every plan

Key features
- Sound mixer
- Each sound has its own volume slider. The free web app carries rain, thunder, waves, wind, fire, birds, crickets, a coffee shop, a singing bowl and white noise, and up to 10 sounds can be active at once.
- Meander
- With Meander switched on, the volume of every active sound drifts up and down at random, so the mix keeps changing instead of looping at fixed levels.
- Timers
- A timer can stop the sounds after a set period, start them after a delay, or fade them out gradually, which the site suggests for falling asleep.
- Saved and shared mixes
- Mixes can be named, saved and switched between. A mix can be shared as a link, and the web app has share buttons for Facebook, Twitter, Reddit and Tumblr.
- Extra sounds with Pro
- The web app lists 15 Pro sounds, among them brown and pink noise, two fan speeds, air conditioning, a city, a stream, a waterfall, three more rain recordings, cicadas and frogs.
- Offline mobile apps
- The iPhone, iPad and Android apps store their sounds on the device, play without a connection and keep running in the background alongside music or podcasts.
