RTL-SDR Radio Receiver for Chrome

A new RTL-SDR Radio Receiver app for Chrome has been released. The source code can be viewed at GitHub. The app is currently capable of receiving broadcast FM stations and scanning between them. To run this app you will need to have the Chrome web browser installed or be running a Chromebook laptop.

Note that at the moment there seems to be a bug in Windows Chrome that prevents this from working.

Radio Receiver is 100% written in JavaScript, but is nevertheless fast enough that it can run on a 2012 Samsung ChromeBook laptop at full quality.


* Stereo FM.
* Scan for stations.
* Unlimited slots for presets.
* Supports the International and Japanese FM bands.
