Moreover, *libcsdr* serves as the base for the new, experimental <ahref="#sdr.js">sdr.js</a>, which takes Software Defined Radio DSP to today's web browsers that provide JavScript JIT compilation.

*sdr.js* is *libcsdr* compiled to JavaScript code with *Emscripten*. Nowadays JavaScript runs quite fast in browsers, as all major browser vendors included JavaScript JIT machines into their product. You can find a <ahref="https://kripken.github.io/mloc_emscripten_talk/cppcon.html">great introductory slideshow here</a>about *Emscripten*.

You can find a <ahref="https://kripken.github.io/mloc_emscripten_talk/cppcon.html">great introductory slideshow here</a>on the concept behind *Emscripten* and *asm.js*.
The purpose of *sdr.js* is to make SDR DSP processing available in the web browser. However, it is not easy to use in production yet. By now, only those functions have wrappers that the front-end of OpenWebRX uses.
