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.

This software is a music tutor: it helps you learning to play an instrument. It guesses the score you are playing, and measures your precision at the task, thus allowing you to improve. It also lets people playing in versus mode.

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.

Various reference programs to read baseband I/Q sample data from a Funcube Dongle Pro+ (FCDPP) software defined radio (SDR) hardware front end, demodulate the data stream and send it to the host's audio output port. Programs are present to demodulate AM, CW, FM and SSB (USB, LSB) streams. Also included is a program that writes FCDPP sample data to its standard output (stdout) port. The programs require the qthid program to control the FCDPP frequency and gain (also available at sourceforge.net. Search for: qthid). Recent activity (10/2014): Added test programs used to construct fun2ssb. See README4; (12/2014) Made program changes to accommodate subsequent complier revisions. For instructions on building qthid-4.1 for Ubuntu 14.04, see a topic under the Discussion menu.

Tool to read and write id3 v2 tags for audio files.

Idi is a voice recognition program intended to help people with physical disabilities to use a keyboard by dictating. It can also be used as a way to remote control your computer or as a nice way to type in your bath.

jackGuitar is a jack capture client which displays the given note you are playing (or could be) on a fretboard without any midi pickup. The UI uses gtk+/cairo, and offers some bells & whistles like changing the tuning or displaying scales & modes on the fretboard.

Wrapper atop "lmms render" - keep rendered tracks up to date with lmms projects. Creates EBU R128 compliat tracks.

A set of plugins for the DSSI synth plugin architecture with GTK-based GUIs, all written in C and C++ using liblo and libglademm. Plugins will include an oscillator, an envelope generator, and a step sequencer.

Pure Data external object to calculate the median of a signal.

This program lets you check a standard MIDI file for errors.

Weakening effect on the MP3 audio encoder and the assimilation of the spectral characteristics of the source. Produced by applying empirical filter (derived from an analysis of a pair of flac-mp3) to the sound in the space R2. 1) Transfer the sound of the space R to R2 (mp3rsrr2); 2) Finding the empirical filter by OLS pair flac-mp3 (mp3rsols); 3) Apply a filter to the sound (mp3rsvalue); 4) Transfer the sound of the space R2 in space R (mp3rsr2r);

mplib is a small, cross-platform C library that is able to handle ID3 tags version 1 and 2. Keywords: id3, mp3, mpeg, tagging

This is a toolkit for transcribing a music audio file to common music notation. This is done by manually annotating a spectrogram or something similar and converting it to a MIDI file and to a abc music notation file.

Propax (Propax Revolution Over Pixapr And Xplsisnjasp) is a hardware visualization project.

Mixing Bhatkhande rules with Traditional and Learning based software techniques to classify of existing as well as predicting new North Indian (Hindustani) Classical Music raaga\'s (raga\'s)

rePhase project has moved to https://rephase.org, please go there to download rephase and to get info, support and updates. rePhase is a FIR generation tool for building fully linear-phase active crossovers with arbitrary slopes. It also let you manually compensate for the phase shifts of your loudspeakers and existing crossovers, be it active or passive. Once generated, the FIR can be applied using any hardware (openDRC, miniSHARC, Najda, ...) or software (foobar, convolver, JRiver, ...), stereo or multi-way convolution engine.

RECWAV gives a processor-efficient display of the spectrograph of an audio file, showing the energy in the sound at each moment and frequency. It was originally developed on a '286 under DOS and now also runs under Linux with svgalib.

Win32 dll to normalize wav pcm files using very well known replaygain algorithm, it can be used as the first pass prior to mp3 encode, notice that BENormalize that is available in the project http://sourceforge.net/projects/rsppmp3/ gives a lot better results than ReplayGain, give it a try

Application to transcribe music. This means recording songs/open audio files and pick out the notes.

tag2html is a tool that converts most important mp3-tags from mp3-files into a html- or xml-file.

Tune is a note/chord detecting program for use with guitars, pianos, or voices. It uses an FFT to analyze incoming sound and computes the root frequency.

vTune is an open-source pitch correction software.

This project contains a pitch detect and a voice endpoint detect algorithm. Also codes for a digital filter and drawing font on bitmap file. It is just for study, nothing more, so be have fun!

Wavefourier is a tool for analysing wave-files with fourier-analysis.
