LabVIEW is a platform and development environment for graphical programming for measurement and automation. It is a development tool available for applications in test and measurement, data acquisition (DAQ), analysis, and instrument control (GPIB, VXI, and serial).

Audio visualization tool for generating detailed spectrograms from FLAC files, featuring customizable parameters and zoom functionality for precise audio analysis.


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...

SigDigger is a Qt5 digital signal analyzer written in C/C++ that runs in GNU/Linux, macOS and Windows. SigDigger uses its own DSP library (sigutils) and a realtime signal analysis library (Suscan) to distribute load, and supports most SDR devices in the market thanks to SoapySDR.

The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types (e.g. logic analyzers, oscilloscopes, and many more).

The Universal Radio Hacker (URH) is a software for investigating unknown wireless protocols.



Csound is a sound design, music synthesis and signal processing system, providing facilities for composition and performance over a wide range of platforms. It is not restricted to any style of music, having been used for many years in the creation of classical, pop, techno...
Technical graphing and data analysis for Macintosh and Windows. IGOR Pro creates publication quality scientific graphics used by scientists and engineers around the world. IGOR Pro 6 is an extraordinarily powerful and extensible scientific graphing, data analysis, image...
inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.




Pyo is a Python module to help DSP script creation. Pyo contains classes for audio signal processing. With pyo, the user will be able to chain such classes directly in Python, and to manipulate them in real time through the interpreter.
Most arbitrage tools are limited to CEXs. UnIQum stands out by integrating DEX Futures (Aster, Hyperliquid) alongside major CEXs (Binance, Bybit), unlocking unique liquidity gaps. Key Differentiators: 1. Hybrid Coverage: We track spreads between CEX & DEX in real-time. 2.




SoapySDR is an open-source generalized C/C++ API and runtime library for interfacing with SDR devices. With SoapySDR, you can instantiate, configure, and stream with an SDR device in a variety of environments. Both osmosdr and uhd devices are available within SoapySDR.
