An open-source software-defined radio app for Mac and mobile devices that streams local FM broadcasts and scanner frequencies via RTL-SDR.
LocalRadio is an open-source software-defined radio application that allows users to listen to local FM broadcasts, music, news, sports, weather, and scanner frequencies using an inexpensive RTL-SDR USB device. It streams captured radio signals over a home network to Mac computers, mobile devices, and AirPlay-compatible systems without requiring additional hardware or software on client devices.
Radio enthusiasts, hobbyists, and cord-cutters who want to listen to local broadcasts and scanner frequencies without traditional radio hardware, particularly those interested in software-defined radio technology and home network streaming.
LocalRadio provides a cost-effective, easy-to-setup alternative to traditional radio receivers by leveraging affordable RTL-SDR hardware and offering a web-based interface that works across all devices on a home network without requiring mobile apps.

Uses inexpensive RTL-SDR USB devices to capture FM broadcasts, aviation, and public safety frequencies, making it a budget-friendly alternative to traditional radio hardware.
Offers an easy-to-use web interface that works on any device with a browser, eliminating the need for mobile apps or additional software on iPhones, iPads, Android, or PCs.
Supports streaming to Apple TV and other AirPlay-compatible devices, enabling whole-home listening over a home network without extra client hardware.
Recent versions add stereo audio for FM broadcasts and compatible devices, enhancing the listening experience for music and other content.
The project is labeled as experimental with pre-release alpha versions, lacking independent testing and not suitable for reliable, production use.
Requires a Mac to host the RTL-SDR device and run the application, limiting deployment for Windows or Linux users who want to serve audio.
Not tested for security with public IP addresses, making it risky for deployments outside a private home network, as admitted in the README.
Involves configuring an RTL-SDR device and home network streaming, which can be challenging for those unfamiliar with software-defined radio or network setup.
