Drum Count is a simple tool which analyzes sound in real-time to measure the number of strokes played on a drumset.

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

This is a Java Just Intonation Calculator. It allows users on many platforms to calculate and hear just tunings. It will support saving and opening tunigs and opening spreadsheet documents and allow users to send tunings to their synthesizers, via MIDI

The project contains a small command line tool (written in Python) that analyses the file structure (ID3 and frame headers) of MP3 files and projects the structure into a JSON object.

A portable utility for checking the consistency of MPEG streams or files. The primary accent of the check is on the seamless flow of frames and tags since most MPEG defects introduced by aborted network transfers manifest theirselves in its breakage.

Basing on the MoodLogic(c) idea, Open SONG db will be the free alternate! It will scan your harddisc for mp3s and then check them online for more detailed information. You will (if somebody else already added this song to the library) get the song's sp

Thérémine is an audio program which reads realtime pitch and volume data from an USB Arduino Theremin, and generates high quality audio signal emulating a realistic instrument. It was originally designed to work with an Open.Theremin.UNO shield (see http://www.gaudi.ch/OpenTheremin), although it should work with other Arduino devices as long as you provide an appropriate program. Thérémine can play a variety of different tones. It comes with another program, Loop bank manager, whose purpose is to extract stationnary, looping samples from recorded wave files. It allows importing new instrumental tones into Thérémine, as long as the source recording contains reasonable data. Two demo sample banks are provided with Thérémine featuring violin and voice tones. Both were made using Loop bank manager.

Linear (or Longitudinal) Timecode (LTC) is an encoding of SMPTE timecode data in an audio signal, as defined in SMPTE 12M specification.

Cross platform 3D midi and audio visualization system. Features an advanced graphics rendering engine, with ogre3d, and a data driven plug-in architecture which allows for programmers and artist to modify and create new "visualization instruments".

AMM - Another Mp3 Manager - Manages Information about your Mp3s, find duplicate Mp3s, get Information from ID3v1-Tags, ID3v2-Tags and from filename, ...

Analyses audio content of songs and downloads information from the web to build a comprehensive descriptive library you can use to generate playlists based on the song mood, theme genre, or virtually any property of the song.

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.

AVI-OGM Info : A simple GUI/console program to get usefull informations from Media files. Supported formats are currently : AVI (*.avi), Ogg Video and Audio (*.ogm, *.ogg), MPEG Audio (*.mp3, *.mpa, *.mp2) and MPEG Video (*.mpg, *.mpeg)

Instrument tuner. It can help you to tune a piano, a guitar ... Accordeur displays spectrum and calculates the pitch really played. A visual bar allows an easy tuning. Instruments and temperaments are customizable.

The software takes midi input (e g from a midi keyboard) and prints on the screen what chord you are currently playing. The idea is to write the chords not the perfect logical way, but the way a musician would write it.

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

This is a tool for collective electroacoustic improvisation. Up to 20 users can particpate using their smartphone and their voices to mould sounds/images recorded live.

Apolo is a personal music suggesting system based on user behavior analysis.

Apoplexy provides simple, fast and direct MP3 management. Allows batch entry of track information (artist, album, track, playlist) and configurable sorting and archival of files. Crafted in finest perl and utilizing the wxPerl crossplatform GUI toolkit,

AuVis is a short command-line program that generates static images based on the audio data read from a WAVE resource. This can be useful when you want to get a quick overview on how loud an audio file is at certain positions.

Audacity Policial (aka Audacity Police) is an extension of Audacity sound editor that was created to help police and justice investigations based on phone call and environmental recordings, supporting audio analysis and transcription.

This is an audio processing project in a very early stage.
