This is a program to store data calculated from the tempo of a song into different degrees of seconds for use with "programming synths". Written in C++ with Visual C++ Express. Java version coming soon.
SuperWillow is a Music Generation program. Artists have many influences which they have accumulated over the years by listening to countless pieces of music, this principle is reflected in SuperWillow.
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.
BeamformIt is an acoustic beamforming tool that accepts a variable amount of input channels and computes an output via a filter&sum beamforming technique. It can process all sorts of data acoustic files, leading to an homogeneous single output.
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.

A collection of scripts and programs to automatically annotate video/audio for subtitles. Basically relies on a MARSYAS (Music Analysis, Retrieval and Synthesis for Audio Signals) plug-in for detecting human voice in polyphonic recordings.
MacVisSTA: Macintosh Visualization for Situated Temporal Analysis.
This is an open source system designed for Mac OS X. This software permits visualization of multiple time-synchronized videos in conjunction with one or more graphical plots/annotations.
Moodtrack contains Python classes for music-emotion analysis and assembly, enabling users to build soundtracks based on emotion and timing. USERS: Music Supervisors/Composers/Producers, Game Audio Developers, Content Providers. FILM DEMO: moodtrack.tv
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.
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.
Open-source content and evaluation framework for music transcription systems. Can be used as monophonic or polyphonic database, through software mixing.
Build your music portal easily. With this PHPNuke module you will be able to publish music information: Artists data, albums, songs, audio samples, chart lists, themes and more. You can install it with no technical knowledge.
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.
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.
Use cicsWave to extract digital audio data from wav files. 16 & 24 bit stereo formats at any sample rate is supported. A csv (comma separated values) file is created which can be used in spreadsheets etc. Only 32000 samples (both) channels are extracted.
A visualization of the fourier transform applied to sound data. Analyzes a time-domain sound sample using the Fourier Transform, and graphically displays the results and sound in real time. Attempts to audio into sheet music.
This is a simple C library for working with the raw data in uncompressed WAV files. There are many better libraries for dealing with WAV files than this one. I wrote this to do some experimenting, and it's probably not the solution you're looking for.
