About:
Luaradio is a lightweight, embeddable flow graph signal processing framework for Software Defined Radio (SDR). It provides a comprehensive suite of processing blocks and supports both LuaJIT and pure Lua for high-performance execution. This allows users to build custom SDR pipelines without the overhead of large frameworks like GNU Radio.

Key Features:

Flow graph architecture with signal processing blocks
High performance via LuaJIT Just-In-Time compilation
Pure Lua fallback for portability and embedded systems
Supports various hardware (RTL-SDR, SoapySDR) and file sources

Use Cases:

Building custom SDR receivers and transmitters
Real-time signal analysis and demodulation
Educational projects for digital signal processing
Prototyping RF communication systems

Alternatives:

GNU Radio – Luaradio is significantly more lightweight and embeddable, whereas GNU Radio offers a larger ecosystem and GUI tools but with a heavier C++ dependency.
Liquid DSP – Luaradio provides a higher-level flow graph abstraction in Lua, while Liquid DSP is a C library focusing on lower-level DSP primitives.
