The Pure Data (short Pd) project on SourceForge unifies the extensions (or externals) written for the Pure Data Graphical Computer Music System written by Miller Puckette with contributions from many others.

Reads audio from Windows audio interface or wave file and creates a continuous spectrum display. Command line support for generating sine, square, triangle and sawtooth wave files. Uses biquad IIR digital filters for frequency detection, plus digital lowpass filters for output extraction. Highly configurable. 60+ FPS with suitable hardware. Manual or automatic gain control.

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

Winboard 4.5 32-bit is a free Windows accessible Chess program that works automatically with the JAWS or the free NVDA screen reader. It is for the blind, low sighted or those who can not use a mouse. It provides vocal announcements of position changes and other selectable board conditions. Blind players also use a separate "tactile chess board". Winboard 4.5 has full keyboard access to move pieces and run menu items. Partial sighted players use high contrast mode and adjust board, piece,...

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.

ManyEars implements real-time microphone array processing to perform sound source localisation, tracking and separation. It was designed for mobile robot audition in dynamic environments. NOTE: Development will continue on github : https://github.com/introlab/manyears

Quickplot is a fast interactive 2D plotter with infinite zooming, value picking, pipe input, and unlimited plots displayed. Quickplot is meant for looking at your data quickly and of secondary importance is making static pictures of your data.

didgmo is a software for DIDGeridoo sound MOdeling. didgmo is capable of predicting the sound characteristica of a didgeridoo by providing its inner geometry. didgmo uses the method of acoustic transmission line modeling.

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

Advanced Speech Signal Analysis library provides a structure to handle various file formats and a variety of analysis functions commonly used in speech processing.

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

Zwicker's Loudness Calculation (ISO532B) Tools. The project includes a loudness calculation program based on Zwicker's Method, and a WAV file analyzer generating data files for loudness calculation. Documentation and test files are also provided.

This is a fast C implementation of Arturo Camacho's SWIPE' pitch extraction algorithm. See the project homepage for more about the advantages of the SWIPE' algorithm. swipe-1.0.tar.gz contains the current source, which should compile quite neatly.

Transana is a cross-platform tool for the transcription and qualitative analysis of audio and video data. It also provides the ability to identify and organize analytically interesting portions of videos, as well as attach keywords to those video clips.

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.

eXtace is a 3D audio visualization tool (or eye candy depending on how you look at it). eXtace requires ESD (Esound) for its sound input source. It performs a FFT (fast fourier transform) on audio and displays it via various graphical modes.

Easy-to-use platform-independent plugin API for the extraction of low-level features from audio data in PCM format, as required in the context of music information retrieval software.

dvbsnoop - DVB analyzer / MPEG analyzer program to monitor, analyze, debug, dump or view dvb/mpeg/dsm-cc/mhp stream information (TS, PES, SECTION) (e.g. digital television) send via satellite, cable or terrestrial.
