inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.
- Large (100GB+) file support
- Spectrogram with zoom/pan
- Plots of amplitude, frequency, phase and IQ samples
- Cursors for measuring period, symbol rate and extracting symbols
- Export of selected time period, filtered samples and demodulated data
Install inspectrum with your package manager, it should be present in most distros.
- cmake >= 3.1
- fftw 3.x
- liquid-dsp >= v1.3.0
- pkg-config
- qt5

inspectrum supports the following file types:
*.sigmf-meta, *.sigmf-data
- SigMF recordings*.cf32
,*.fc32
,*.cfile
- Complex 32-bit floating point samples (GNU Radio, osmocom_fft)*.cf64
,*.fc64
- Complex 64-bit floating point samples*.cs32
,*.sc32
,*.c32
- Complex 32-bit signed integer samples (SDRAngel)*.cs16
,*.sc16
,*.c16
- Complex 16-bit signed integer samples (BladeRF)*.cs8
,*.sc8
,*.c8
- Complex 8-bit signed integer samples (HackRF)*.cu8
,*.uc8
- Complex 8-bit unsigned integer samples (RTL-SDR)*.f32
- Real 32-bit floating point samples*.f64
- Real 64-bit floating point samples (MATLAB)*.s16
- Real 16-bit signed integer samples*.s8
- Real 8-bit signed integer samples*.u8
- Real 8-bit unsigned integer samples
If an unknown file extension is loaded, inspectrum will default to *.cf32
.
Note: 64-bit samples will be truncated to 32-bit before processing, as inspectrum only supports 32-bit internally.
