history
Project history and usage
inspectrum is an offline signal-analysis application for captured radio samples, especially software-defined radio recordings. Its package-manager niche is practical DSP tooling: a Qt spectrogram viewer that turns raw capture files into measurements, symbol extraction, and exportable slices.
Project history
The GitHub repository was created in 2015 under miek/inspectrum, and the first tagged release, v0.1, appeared later that year. The README describes a desktop tool for analysing captured signals from SDR receivers, with support for very large files, spectrogram navigation, amplitude/frequency/phase/IQ plots, cursors, symbol extraction, and export of filtered or demodulated data.
The release history shows a gradual widening of file-format and analysis support. Version 0.2 added extra plots, cursors, symbol extraction, data export, and additional SDR sample formats; later releases added support for real-valued samples, SigMF files and annotations, Qt 6, and SigMF datasets.
Adoption history
The README points users to Linux distribution packages, Homebrew, MacPorts, radioconda, and conda-forge, which places inspectrum in the cross-platform SDR packaging ecosystem rather than only as a source build for radio hobbyists.
Homebrew packages inspectrum from its tagged GitHub source archive and reports installation activity for the formula, while the input metadata also records packages in Debian, Ubuntu, MacPorts, Nix, Arch, and openSUSE-style package managers.
How it is used
The documented usage is to run inspectrum against a capture file. The README lists common SDR sample extensions such as cf32, cs16, cu8, SigMF metadata/data pairs, MATLAB-style real samples, and HackRF/BladeRF/RTL-SDR-oriented integer formats.
The tool is used after capture rather than during acquisition: users record samples with SDR hardware or another program, then inspect timing, symbol rates, modulation traces, and extracted regions offline.
Why package nerds care
For package maintainers, inspectrum is a compact example of the SDR stack in a desktop formula: Qt, FFTW, liquid-dsp, CMake, and a file-format-heavy UI for raw binary data. It is more specialized than a generic plotting tool and more packageable than a complete GNU Radio workflow.
Its importance comes from occupying a small but useful slot between low-level SDR capture utilities and larger radio-analysis environments: a single executable that can be installed from a package manager and pointed at raw samples.
Timeline
- 2015: GitHub repository created and v0.1 release published.
- 2017: v0.2 added extra plots, cursors, symbol extraction, data export, and more sample formats.
- 2020: v0.2.3 added real-valued sample support and Qt 5.15 build fixes.
- 2023: v0.3.1 added SigMF files and annotations.
- 2025: v0.4.0 added Qt 6 and SigMF dataset support.
Related projects
- inspectrum sits near GNU Radio, osmocom tools, HackRF, BladeRF, RTL-SDR, SDRAngel, liquid-dsp, FFTW, SigMF, radioconda, and conda-forge packaging for radio/DSP workflows.
