Spectrum Spectogram Analyzer was designed with accuracy and easy of use in mind. It can be used for monitoring or measuring environmental sound or noise; help tuning instruments; timing short sound events; and educational purpose.


GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like...

Spectro is a freeware audio file analyzer for windows. Currently capable of reading FLAC, APE, MP3 and WAV files. Spectro lets you view vital data about compressed audio files and creates a spectrogram of the wave data.


inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.




The Gnome Chemistry Utils include six chemistry related programs:




Baudline is a time-frequency browser designed for scientific visualization of the spectral domain. Signal analysis is performed by Fourier, correlation, and raster transforms that create colorful spectrograms with vibrant detail.




A graphical application for showing the Fast Fourier Transformation (FFT) as graph and waterfall diagram of the radio spectrum retrieved by Software Defined Radio (SDR) devices supported by GrOsmoSDR. Plugins enable demodulating a selected signal.


Modeled after the spectrum effect in Ableton Live , Spectrum is a free and open-source web app that shows frequencies of an MP3 or OGG file in real-time.


A multi-purpose graphical, educational, scientific, interactive, online, multimedia presentation / physics tool to explore, learn, calculate and visualise everything around the electromagnetic spectrum. Shows bands, discrete frequencies, graphs..
