After making the changes at the retrogram-rtlsdr project, i got the "virus" to make something even more better and in a language i know better, as C is not my thing. So Python it was, as it may not be the faster, but it has great support and anyone can contribute, as it is a well known programming language.
For sure, it needs some refinement and work some quirks, but it's functional and it has more than any other text based SDR project... at least, i know off. Just grab a copy and "play" with it. Get it at my Github repo... https://github.com/xqtr/PySpecSDR
