TinyRadio
A simple software-defined radio (SDR) receiver with a terminal UI, built in Zig.
What it does
TinyRadio turns your RTL-SDR dongle into an AM/FM radio with a text-based interface. It's not pretty, it's not optimal, its probably not even acturate, but it makes music come out of the air.
Requirements
- Zig (latest version)
- RTL-SDR dongle and drivers (
librtlsdr) - PulseAudio (Linux)
Installing RTL-SDR drivers
Devbox
devbox shell
Running
zig build -Doptimize=ReleaseFast run
Controls
- ↑/↓ - Tune frequency
- B - Switch AM/FM bands
- M - Mute/unmute
- -/+ or ←/→ - Volume down/up
- 1-6 - Load presets
- Q or Ctrl+C - Quit
Dependencies
This project is powered by the excellent zigradio library by vsergeev, which does all the heavy SDR lifting. Massive credit to that project for making software-defined radio flow graphs in Zig!

Note
This is a quick-and-dirty radio app. If you're new to Zig, this might be a fun project to explore, but don't expect production quality. It's more of a "look, SDR works in Zig!" proof of concept.
