Run
./inspectrum [filename]
Input
inspectrum supports the following file types:
-
*.sigmf-meta, *.sigmf-data
- SigMF recordings -
*.cf32
,*.cfile
- Complex 32-bit floating point samples (GNU Radio, osmocom_fft) -
*.cf64
- Complex 64-bit floating point samples -
*.cs16
- Complex 16-bit signed integer samples (BladeRF) -
*.cs8
- Complex 8-bit signed integer samples (HackRF) -
*.cu8
- 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.
