soapysdr-fft-log is a tool for logging and playing back arbitrarily large portions of the RF spectrum. it can also identify peaks based on a handful of input parameters and log them to console. It is a sister project to plutosdr-fft-log which brings support to many of the most popular SDRs. scanner.py continuously scans a specified frequency range and logs the FFT results to .bin files. each log file contains data for an arbitrary large portion of the spectrum, allowing continuous spectrum monitoring. replay.pl plays back FFT log files generated by scanner.py, printing detected peaks to the console.
