GNU Radio Companion is making access to software-defined radio easier with a version that can be used through a browser. Developed by [Marc Lichtman], the tool offers sample flowcharts; it supports various SDRs, including RTL-SDR, as well as sound cards and recorded radio broadcasts.
The browser version is said to offer the functionality of the desktop version, except for network-connected SDRs.
Why it matters
Browser-based use lowers the technical barrier for those who want to try software-defined radio tools, while offering the opportunity to evaluate different hardware and content sources in the same environment. This scope directly concerns those using RTL-SDR, those working via a sound card, and those working with recorded radio broadcasts. Ready-made flowcharts make it possible to examine functions and compare ways of using the system without setting it up from scratch. However, the lack of support for network-connected SDRs means that the browser version is not a full equivalent of the desktop version for users working with such connections; therefore, which mode of operation is preferred depends on the connection method of the SDR being used.
