  "github_readme_excerpt": "# inspectrum\ninspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.\n\n![inspectrum screenshot](/screenshot.jpg)\n\n## Features\n * Large (100GB+) file support\n * Spectrogram with zoom/pan\n * Plots of amplitude, frequency, phase and IQ samples\n * Cursors for measuring period, symbol rate and extracting symbols\n * Export of selected time period, filtered samples and demodulated data\n\n## Install\n### Linux\nInstall inspectrum with your package manager, it should be present in most distros.\n\n### macOS\n * [Homebrew](https://formulae.brew.sh/formula/inspectrum)\n * [MacPorts](https://ports.macports.org/port/inspectrum/)\n\n## Windows\n * [radioconda](https://github.com/ryanvolz/radioconda)\n * [conda](https://anaconda.org/conda-forge/inspectrum)\n\n## Build from source\n### Prerequisites\n\n * cmake \u003e= 3.1\n * fftw 3.x\n * [liquid-dsp](https://github.com/jgaeddert/liquid-dsp) \u003e= v1.3.0\n * pkg-config\n * qt5\n\n### Build instructions\n\nBuild instructions can be found here: https://github.com/miek/inspectrum/wiki/Build\n\n### Run\n\n    ./inspectrum [filename]\n\n## Input\ninspectrum supports the following file types:\n * `*.sigmf-meta, *.sigmf-data` - SigMF recordings\n * `*.cf32`, `*.fc32`, `*.cfile` - Complex 32-bit floating point samples (GNU Radio, osmocom_fft)\n * `*.cf64`, `*.fc64` - Complex 64-bit floating point samples\n * `*.cs32`, `*.sc32`, `*.c32` - Complex 32-bit signed integer samples (SDRAngel)\n * `*.cs16`, `*.sc16`, `*.c16` - Complex 16-bit signed integer samples (BladeRF)\n * `*.cs8`, `*.sc8`, `*.c8` - Complex 8-bit signed integer samples (HackRF)\n * `*.cu8`, `*.uc8` - Complex 8-bit unsigned integer samples (RTL-SDR)\n * `*.f32` - Real 32-bit floating point samples\n * `*.f64` - Real 64-bit floating point samples (MATLAB)\n * `*.s16` - Real 16-bit signed integer samples\n * `*.s8` - Real 8-bit signed integer samples\n * `*.u8` - Real 8-bit unsigned integer samples\n\nIf an unknown file extension is loaded, inspectrum will default to `*.cf32`.\n\nNote: 6",
