sdrtop – terminal monitor for software-defined radio hardware

sdrtop monitors software-defined radios in the terminal with live spectrum, waterfall, RF measurements, signal decoding and IQ recording.

Spek-rs generates audio spectrograms using FFmpeg, with configurable colour palettes, drag-and-drop support and graphical spectral analysis.

Open Sound Meter provides real-time spectrum, phase, impulse response, coherence, delay and SPL measurements for sound system tuning.

Soundscope analyses recordings and live audio through terminal displays for waveforms, FFT spectra, LUFS loudness and true peak levels.

spectroterm displays live audio spectra in the terminal with frequency axes, configurable colours, falling bars, peak markers and PipeWire support.

AudMeS combines an oscilloscope, FFT spectrum analyser, tone generator, distortion measurements and frequency-response testing.

Cava creates responsive audio spectrum visualisations with terminal and graphical displays, custom colours, shaders and multiple audio inputs.

myriacat is a spectrum analyzer with VLF SDR. It’s designed to be fast, intuitive to use, portable, and lightweight.

Friture analyses live audio with FFT spectra, spectrograms, octave measurements, level meters, oscilloscopes and delay estimation tools.

Spek displays audio spectrograms with adjustable frequency windows, dynamic range, colour palettes and channel selection for detailed analysis.

sndpeek visualises waveforms and spectra with a 3D waterfall, Lissajous display and real-time extraction of acoustic features.

rtspeccy displays live audio spectra and spectrogram history with OpenGL, frequency guides, freeze controls, zooming and panning.
