inspectrum

inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.

Try it

sudo apt-get install qt5-default libfftw3-dev cmake pkg-config
mkdir build
cd build
cmake ..
make
sudo make install

brew install qt5 fftw cmake pkg-config
mkdir build
cd build
CMAKE_PREFIX_PATH=$(brew --prefix qt5)/lib/cmake cmake ..
make install

sudo port install fftw-3-single cmake pkgconfig qt5
mkdir build
cd build
cmake ..
make
sudo make install

./inspectrum

Currently inspectrum can only read files with interleaved (complex) 32-bit floats, such as those produced by GNURadio or osmocom_fft.

Be fast and light
Make as many settings as possible work in realtime. I want this to be a useful tool for visually learning about DSP by tweaking around with things like FFT settings, filter widths or clock synchronisation.
Support large files - as large as possible, but at least several GBs.
Future features: filtering, demodulation, clock sync. Probably based on GNURadio.
