AUDio MEasurement System - a multi-platfrom system for audio measurement through sound card in the PC. It contains: generator, oscilloscope, audio spectrum analyzer (FFT) and frequency sweep plot. Compiles and works under Linux, Windows and MacOS. Source code is available in "git" and as ZIP snapshot. For more information see README.md

... Electronic's GMC-300/500/600 Geiger counters, RadMon, Gamma-Scout Geiger counters, audio-click Geiger counters, IoT devices, I2C based sensors. New is the support of the RadPro firmware, suitable for various low-cost Geiger counters. GeigerLog reads data from devices, saves them to databases, prints to screen and plots as auto-updated, customizable graphs. Quality control using Statistics, Scatter, Poisson, FFT & Autocorrelation, and more. The Raspberry Pi 5 qualifies as full GeigerLog host.

This project provides the SOFA Toolbox, a toolbox for the Spatially Oriented Format for Acoustics (SOFA). The SOFA Toolbox is the successor of the SOFA API for Matlab/Octave. More information on the SOFA Toolbox can be found at https://github.com/sofacoustics/SOFAtoolbox. SOFA is a file format intended for reading, saving, and describing spatially oriented data of acoustic systems. Examples of data are head-related transfer functions (HRTFs), binaural room impulse responses (BRIRs),...

LDCT is an open source, cross-platform application containing many calculations commonly used in loudspeaker design.

Qt-based software for audio measurement (speaker parameters, frequency and phase response, etc).

A portable loudspeaker design system supporting measurement, modeling, simulation and optimization of boxes, filters and systems.

Software oscilloscope using Python and tkinter. Supports multiple sources: socket, file, audio, USB. Displays data by samples, time or frequency. Scales the input automatically or manually.

DRC generates digital room correction FIR filters to be used within HiFi systems in conjunction with real time convolution engines like BruteFIR.

Antenna, a free and open-source dvb-t (terrestrial digital tv) tuner for linux desktops. Antenna is a full featured tool to see what's going on in the sky. It enables you to scan, watch and record television, radio and services broadcasted on air.

SoundRuler is a tool for acoustic analysis, graphing and teaching. It interactively recognizes and measures 35 temporal and spectral properties of each sound in a file. It also features several measurement, graphing and didactic modules.

Luscinia is a program for archiving and analyzing field sound recordings (especially of animals). It incorporates an interface to a database, spectrogram measurement algorithms, sound comparison algorithms, and statistical analysis.

A cross platform dual channel FFT based Acoustic Analysis Tool to help engineers analyze live professional sound systems using the transfer function. One feature is the ability to capture four sample plots, average them, and invert to aid in final EQ

This project is the MATLAB development of a virtual sound level meter. The program will read in a calibrated .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter. The software implements Fast, Slow, Impulse and LEQ; A, C and Flat Weighting; Ln and Noise Dose analysis; Octave and 1/3 Octave band analysis; high resolution FFT analysis and spectrograms. Band analysis can be made using fast FFT methods or slower, but ANSI standard...

Software oscilloscope using Python and tkinter. Supports multiple sources: socket, file, audio, USB. Displays data by samples, time or frequency. Scales the input automatically or manually. It has been renamed "pdatascope" to avoid a name-clash with Pyscope, a scoping package on PyPi. See https://sourceforge.net/p/pydatascope/ for the latest code.

This is a framework used to convert files from one format to another, while providing a measurement of the accuracy and fidelity of the conversion process

A python-based calculator that uses the Sabine, Norris-Eyring and Fitzroy formulae to calculate the RT60 time of a room with given specifications. Material list from SAE Institute reference.

esweep is a scriptable audio measurement program which features various signals and signal processing functions. Its main purpose is the measurement of speakers.

DTMF detector library and/or application that reads in the specified audio file and returns/outputs whether DTMF detected and/or list of detected digits. May have GUI and command line interfaces.

openEAR is the Munich Open-Source Emotion and Affect Recognition Toolkit developed at the Technische Universität München (TUM). It provides efficient (audio) feature extraction algorithms implemented in C++, classfiers, and pre-trained models on well-known emotion databases. It is now maintained and supported by audEERING. Updates will follow soon.

This software generates a distorted version of an audio file that can give a required audio quality. This is for use with subjective tests, such as MUSHRA, where an anchor is required of a particular quality.

Maximum Length Sequence and Sinusoid Sweep response measurement library that uses the soundcard to measure loudspeakers and electrical systems.

WISL performs network performance measurements and dynamically generates sounds (music) that represent the current state of the network. It is highly extensible: individuals can contribute soundpalettes or measurement modules.
