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.
MP3val is a small, high-speed tool for MPEG audio files validation and (optionally) fixing problems. It was primarily designed for verification of MPEG 1 Layer III (MP3) files, but supports also other MPEG versions and layers.
Rakarrack is a stereo digital effects processor for Linux with jack support. Standard line-up of nearly 40 effects modules include Equalizers, Reverbs, Echo, Flange, Chorus, Distortions, WahWah, Vocoder, and other filters and processing modules.
AUDio MEasurement System - multi-platfrom system for audio measurement through sound card in the PC. Incorporates Generator, Oscilloscope, FFT, Sweep frequency characteristic. Now it can be compiled and works under MSWindows and Linux.
Yet Another Audio Feature Extractor is a toolbox for audio analysis. Easy to use and efficient at extracting a large number of audio features simultaneously. WAV and MP3 files supported, or embedding in C++, Python or Matlab applications.
KGuitar is powerful KDE-based music tabulature editor with support of guitar, drums, classic note scores, MIDI synthesizer output, chord, scales, modes, melody and rhythm construction and analysis tools, lots of tab effects, Guitar Pro files import.
A convolution plug-in for Windows Media Player, DirectShow/DX (for use with ZoomPlayer Pro, Media Player Classic, etc) and VST. Allows cross-feeding of channels. For room correction, bass management, cross-overs, equalization, etc.
A subband sinusoidal modeling library/command line tool/gui for time stretching and pitch scaling audio. Download the sbsms package for the source or the win32/mac wxSBSMSPlayer package for the gui binaries.
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
This program removes clicks, pops and bitrots from audio files
There is a one common problem in capturing audio from old vinyl disks. Many of the disks have scratches that impose needles to make little jumps producing short sharp noises named 'click'. My project's aim was to create a free software which able to remove this kind of noise from audio files produced by capturing vinyl disk. Also the application is able to remove some other kinds of short sharp noises like 'bitrots'. The program can detect start positions and lengths of clicks and replaces the damaged samples with interpolated ones automatically. Win 10 users can add the app from Wondows Store.
VLevel is a dynamic compressor which amplifies the quiet parts of music. It uses a look-ahead buffer, so the changes are gradual and the audio never clips. It is a command line filter and a LADSPA plugin, so it works with XMMS.
FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display. It provides several algorithms for processing audio data in the frequency domain with a highly interactive GUI to manipulate and display the spectral data.
IMMS is an intelligent playlist plug-in for XMMS that tracks your listening patterns and dynamically adapts to your taste. It is incredibly unobtrusive and easy to use as it requires no direct user interaction.
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.
A C++ library and Python module for audio synthesis featuring dynamic digital filters. Nsound lets you easily shape waveforms and write to disk or plot them. Nsound aims to be as powerful as Csound but easy to use.
The open source, multimodal interactive "Sensitive Artificial Listener" dialogue system created by the EU project SEMAINE.
virtuodrive is a distortion effect plugin for guitar, it's available in vst and jesusonic format
baptools - broadcast audio production tools
AnaWave is a project for musicians, analyse a wave file for retrieve chords. Majors and minors for the moment, this project is open for include 7eme..... VS, MFC
This project will try to develop an audio analyser which displays several informations as phase in 2 ways (1 dimensional and 2 dimensional), waves shapes, spectrogram in full range and by 1/3 octavia with the value of the current peak frequency, and meter
VST Plugin for real time analysis of MP3 coding. This plugin is suitable to reproduce on the fly the "hearing" effect of MP3 compression.
NOTE: Project is looking for a new maintainer MPEG Maaate is a platform to do compressed-domain analysis of mpeg audio files (mpeg-1 layers 1,2,3), which includes mp3 files. The library has a bunch of filters which are implemented as plugins, such as histogram, pauseRate, signalMagnitude etc. (last successful compile was probably round 2005)
beatFinder is an beat analysis tool for percussive music. Beat tracking is interactive and output data can be produced either as numerical beat positions or as audio click or counting tracks.
Rescue deleted TS (mpeg transport stream) files
This program allows to detect and reconnect fragments from deleted TS (MPEG transport stream) files. You can use this to recover files from a hard disk after a crash or an erroneous deletion.
Automatic BPM (Beat Per Minute) detecting application. It can also store detected BPMs into tags.
