Re: [Openbts-discuss] [Discuss-gnuradio] Free Signal Analysis Tool

[Isaac Gerg]

No, Im not sure GnuRadio is what I need. Let me be a little more clear in my needs.  What I need is a tool to analyze time domain data (signals, if you will).  It could be RF, could be seismic, could be acoustic.  I just need a free tool that lets me load up time series data and do things like perform various FFTs, etc WITHOUT having to write any code.  Somethink  like SigView but free and/or open source.  Many companies who make RF rxs or geophones have such tools but they are developed in house and often use matlab with a gui front end (no coding!)  These tools are designed to let someone quickly look at a signal and determine coarse attributes from it like time up/down, bandwidth, spectral shape, etc.

I think gnuradio is basically what you're looking for. I'm still very
new to using it, but I've seen it have frequency analysis tools, and
generally it lets you build whole signal analysis flows visually or
programmatically using python (I think a much better language then
matlab's).
