Open Source Audio Analysis Software

MP3Gain analyzes and losslessly adjusts mp3 files to a specified target volume. It does not simply do peak amplitude normalization. Instead, it performs statistical analysis to determine how loud the file actually sounds to the human ear.

Finds problems in MP3 files and helps the user to fix many of them using included tools. Looks at both the audio part (VBR info, quality, normalization) and the tags containing track information (ID3.) Also includes a tag editor and a file renamer.

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.

MediaInfo is a convenient unified display of the most relevant technical and tag data for video and audio files.

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

As a library of classes for generating and manipulating music and sound, jMusic provides a solid framework for computer assisted composition in Java. jMusic has a music data structure based upon note/sound events and methods for modifying and structu

CECILIA is an environment for music and signal-processing that uses Csound as its underlying audio processing engine. One can think of CECILIA as a completely programmable sound-processing tool, with real-time interactive processing on soundfiles or live

mp3stegz is an application that apply steganographic (steganography) algorithm in mp3 files. mp3stegz will maintain original mp3 file's size and sound quality. The hidden message is compressed(zlib) and encrypted(Rijndael).

Both the Midas M32 and Behringer X32 share the same design of show management using the console GUI, M32-Edit and X32-Edit apps. This app provides an alternative method to manage these show files (cues, scenes and snippets). It provides an easier method of reorganizing and importing/exporting of files.

DuMP3 is a duplicate and similar file finder. It finds exact duplicate binaries by hash, similar text files by substring content, images (JPG, BMP, GIF, PNG, etc) by color and audio files (MP3, WAV, OGG, etc) by wave data. Future: fonts, video.

Program performs bird species recognition by their voices. In early stage of development but working well with some popular species and good samples quality.

Csound is a sound and music synthesis 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 at least classical, pop, techno, ambient. Csound is now hosted at https://github.com/csound Binary and source-code releases: http://csound.github.io/download.html Mailing lists are hosted by HEAnet at https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND and https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND-DEV Archives: mail lists at http://dream.cs.bath.ac.uk/Csound-archive releases: http://dream.cs.bath.ac.uk/Csound-archive/OldReleases/

Annoyed by listening to music you already listened years ago? This command line utility sorts out new MP3s that you already have and reports the ones you like that are in a better quality.

General C++ Library, with modules for Computer Vision, Pattern Recognition and much more.

Scratchlib is a platform independent C++ library to detect the position, speed and direction of the timecode records "Stanton Final Scratch" and "Mixvibes v1"

A set of Qt/C++ classes enabling cross-platform sound recording and pitch recognition. Can be used in software (e.g. instrument tuners, sound dictation, music teaching and tests) as a user input method. Includes a guitar-tuner example.

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