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

Native MacOSX realtime, Altivec powered sound processing application

CoRoPa stands for Computational Rough Paths. The aim of CoRoPa is to provide a software framework for various ideas related to Rough Path Theory, including rough differential equations and the digital description of serial data streams.

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

The Cortex Manager application is designed to help users manage their music on storage devices used with the Cortex HDC-1000, HDC-3000, HDTT-5000 and others.

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.

Free music instruments tuner with gtk+ interface.

Ekstasis is currently a rapidly produced prototype version of a Digital Signal Processing (DSP) framework which seeks to provide signal/data processing modules which can be strung together via Boost library interprocess message queues. Tools for creating and destroying the communication queues, loading/saving PCM 44100 Hz to/from the signal processing chain, windowing the data (currently only a Hann windowing function module), performing a Discrete Fourier Transform (DFT) on the data (using FFT, currently only real part), detecting the presence of an event within a data segment/packet via normalized spectral signature matching/comparison, and the generation of a midi file from the detection of said patterns (i.e., event occurrences) as output are currently available.

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

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.

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.

Framework for Digital Image Analysis

Freetantrum is an umbrella codename for the open-source projects of eTantrum, Inc, including the eTantrum Songprint music identification library.

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.

Gertie is a set of synchronization tools for synching animation with a recorded soundtrack, and can also be used as a synch tool for composers writing music for recorded video.

HASAS (HydroAcoustic Signal Analysis System) is a modular system for passive sonar signal analysis. It can be used for biological research or surveillance, for example. The soundcard is used as input device, and it currently includes all the very basic fu

Harmonia is a tool for analyzing music scores exported to MIDI or MusicXML format. It allows you to detect voices inside a single MIDI track (eg. live piano recording), main themes (and their motifs), harmonic key and chord interpretation.

A KDE instrument tuner. Displays the pitch and amplitude of audio signals.

IOverflow aims to be a 3D shooter game with a visual style loosely based on the game "Rez". It features a 3D Landscape that responds to the (player selected) music actually playing. (will also work as a fancy 3D screensaver)

This is a simple DSP simulator for educational purposes: developed as a course supplement of CIT-4617 (Digital Signal Processing) at Islamic University of Technology (IUT). Written in C++.

IcePick is the real guitar hero. IcePick aspires to be the open source alternative to Guitar Rising or Little Big Star. It presents the guitar player with an animated tab and rates their playback in realtime.

The purpose of this project is to provide a biometric security solution by using voice print, fingerprint and/or facial recognition along with a password and/or smart card support using AES to protect data. Please read forums for if interested.

Katmus is an application for manual music transcription. It features a score editor synchronized with a wave file, time stretching, project manager and lots of other features.

Kwave is a sound editor for the KDE environment. It is written with KDE/QT and is extendable through a powerful plugin interface. For the moment it supports .wav files and many other formats, recording/playback via PulseAudio, Qt Multimedia, OSS and ALSA and some simple effects
