HCI for audiovisual live performance exploiting physical computing. Transform your standard musical instrument - electric bass, guitar, violin, piano etc - in an augmented tool, an audiovideo controller without exploiting any specific ext. hardware.

"CAGE", the Computer Audio Garden in Eclipse, is to be an Eclipse-based, Java and XML workbench, for the computer music composer. It will use the Rich Client Platform to provide a basic backbone framework, enabling existing computer music tools to be p

CAMEL (Content-based Audio and Music Extraction Library) is an easy-to-use C++ framework developed for content-based audio and music analysis. The framework provides a set of tools for easy Segmentation, Feature Extraction, Domain Extraction, etc.

CQT-FW(Constant Q transform with Fixed length Window) is a time-frequency transform for multiple pitch recognition in audio signals(songs). The transform CQT(Constant Q Transform) provide analisys frequencies in a exponencial way, like music does, but it have problems with the time resolution. In CQT-FW we have the same frequency resolution as CQT, but with fixed length windows in time, what leads to a constant time resolution as well. And more, time and frequency resolution are not dependent like in CQT end DFT transforms. We also propose a post processing witch eliminate the high order harmonics, leaving only the fundamental frequencies. The transform got good results in a good range of frequencies, but still have problems in low frequencies.

Realtime construction of audio manipulation chains :: simple plugin architecture :: GTK--

Chordfinder is an useful tool for musicians, in order to find chords and scales.

A set of tools for psychoacoustic research. Initially implemented: * correlograms (and sonograms too) * Lyons' cochlear model * impulse-domain transform using FIR filters (and inverse transform)

Native MacOSX realtime, Altivec powered sound processing application

These are simple command line audio tools to examine, change the gain, and convert wave and raw audio files.

Computer Musicians\' World is a music creator, modeller and manipulator program. With texture analysis you can represent the structure of music. A score editor, wave editor and a tracker also included as other types of music models.

A command-line tool for applying the continuous wavelet transform with respect to predefined wavelets to sampled data.

The project aims to identify a simple and low cost eddy current probe that can be interfaced directly to ordinary linux systems and develop software to record data and identify hidden corrosion on aircraft during their mandated annual inspections.

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/

The DataTime Process Framework is intended to support the processing of time-based data in a modular, concurrent, distributed and extensible manner. C++, using YARP, ACE, Qt and MUSCLE on Linux, OSX, Windows and Solaris.

Can detect digitalizing errors (like silences, saturations and identical samples) in audio files (wav). Scan audio files for statistics like the peak value.

Diglo is a Music Information Retrieval System based on Computer Vision and Audio Spectrum Analysis, using algorithmic operations to find emergent patterns in musical performance. Also it functions as a low-cost Motion Capture Analysis system.

Free music instruments tuner with gtk+ interface.

Audio classifiers are models that are able to predict whether a sound is something or not. The creation of such classifier is normally hard and requires help from an expert. EasyClassifier intends to make the creation of good audio classifiers more intuitive for inexperienced users. For Guides, check our wiki: https://sourceforge.net/p/easyclassifier/wiki/Home/ Under the hood, EasyClassifier uses ACE and jAudio from JMIR(http://jmir.sourceforge.net/). Please, email bugs to easyclassifier@gmail.com

EchoDroid is an Android java project that allows you to identify sounds through the Echo Nest 'EchoPrint' open framework.

Exscalibar is an EXtendable, SCalable Architecture for Live, Interactive or Batch-orientated Audio-signal Refinement.

This project implements the MPEG-7 Audio Spectrum Envelope and Audio Spectrum Projection descriptors.
