Open Source Linux Data Visualization Software

wavesurfer.js is a customizable audio waveform visualization, built on top of Web Audio API and HTML5 Canvas. With wavesurfer.js you can create anything from an HTML5 audio player to a sophisticated DJ application. wavesurfer.js works only in modern browsers supporting Web Audio. It will fallback to Audio Element without graphics in other browsers (IE 11 and lower). You can also try wavesurfer.swf which is a Flash-based fallback. The audio will start playing as you press play. A thin line will be displayed until the whole audio file is downloaded and decoded to draw the waveform. Web Audio needs the whole file to decode it in the browser. You can however load pre-decoded waveform data to draw the waveform immediately. wavesurfer.js runs on modern browsers supporting Web Audio, including Firefox, Chrome, Safari (desktop and mobile) and Opera.

xoscope is a digital oscilloscope using input from a sound card or EsounD and/or a ProbeScope/osziFOX and will soon support Bitscope hardware. Includes 8 signal displays, variable time scale, math, memory, measurements, and file save/load.

Quickplot is a fast interactive 2D plotter with infinite zooming, value picking, pipe input, and unlimited plots displayed. Quickplot is meant for looking at your data quickly and of secondary importance is making static pictures of your data.

The PAMGUARD project develops software to help detect, locate and classify marine mammals using Passive Acoustic Monitoring. This project is being migrated to github at https://github.com/PAMGuard. Please go there for the latest updates. thank you sourceforge for hosting us for all these years.

Software oscilloscope using Python and tkinter. Supports multiple sources: socket, file, audio, USB. Displays data by samples, time or frequency. Scales the input automatically or manually.

NATSpectrum is a skinnable Spectrum Analyzer, Guitar Tuner, and Quick Volume Control. NS visualization mimics WinAMP 2.x style. NS is written in pure Win32 C++ and uses DirectDraw and DirectSound. (FFT, Frequency, Mixer, Microphone, DirectX, PNG, Record)

FrAid(FRactal AID) is an interface to Java, allowing it to proc. math. data(functions/equations). A compl. standalone system utilizing the FrAid prog. lang. is available(no need to be Java programmer to use it!). Use instead of Matlab. High res. graphics

Extremely Lightweight Beat Detection Algorithm - BeatDetektor uses a very simple statistical model designed from scratch by myself to detect the BPM of music and provides real-time feedback useful for visualization and synchronization.

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.

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

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

MouseGestureComposer is a graphical partition editor for visual artists and musicians. Basic elements are mouse movements, placed on a timeline segmented in measures, similar to classical music. Uses processing.org. Developed by numediart.org. A video tutorial is available here: http://vimeo.com/33442844 Main developper: François Zajéga - http://www.frankiezafe.org

Musical Notation System Using a GUI with a built in text editor, one can create a score with the appropriate notations. All musical notations are then transformed into a graphical representation and can be exported into various formats (pdf, ps, eps).

Pumilio is a web-based sound analysis and archive system for almost any kind of sound file with tools to see the spectrogram of the sound, select regions for further analysis and insertion in a database, filtering, and many other manipulations.

Qwav is a waveform extension to the Qt GUI application framework from Trolltech AS of Norway. It's a C++ library that provides a mono and stereo waveform widget and more.

RDV is a visualization environment for scientific and engineering data. Built on top of the RBNB dynamic data server, it supports local and remote data sources and can visualize numeric, video, image, and audio data in a number of different ways.

This project delivers Linux support (USB driver and Tools) for a Digital Signal Processor (DSP) cards of the Signal Ranger series, see http://www.softdb.com/product_dsp.shtml for details) connected to a Linux host via USB.

Sonogram and waveform display programm for Unix using different algorithms like FFT and LPC to display musical features or potential artefacts that you may no be able to hear. Superimposed tuneable Staff-Lines allow for easy transcription of music.

The Secret of NIM is a software writen in PHP/MySQL and JavaScript. It shows a graphical representation of a logic scheme with wires connecting logic modules which have specific parameters. This software has been developped for NIM/TTL logic, thus his simplicity allows also the representation of other logic systems, numeric systems or analogic systems i.e. the pedal board of an electric guitar. The Secret of NIM is divided in two parts. The first one is the main part of the software. It edit different project, connect modules with wires and edit the parameters of those modules. The other part of the sofware is an utility. It edits the modules which will be used for the projects or create them if they aren't in the database yet. The Secret of NIM is a all-in-one software, easy to use and very helpful for saving the wiring of an experiment. But it can't do the logic itseft, it allows only a visualisation of the logic.

A project designed to convert numerical data in various formats into playable sound files for visualization and classification purposes.

Oscilloscope software for Linux and X11. It uses sound device (/dev/dsp) as input source. Two channel (stereo), variable sampling frecuency, time and V scales. Variable trigger mode, level and channel . Nice xforms GUI. Includes buffer circuit scheme (wi

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.

jATLAS is a Java implementation of ATLAS [Architecture and Tools for Linguistic Analysis Systems]. For more information, see http://jatlas.sourceforge.net.

Software oscilloscope using Python and tkinter. Supports multiple sources: socket, file, audio, USB. Displays data by samples, time or frequency. Scales the input automatically or manually. It has been renamed "pdatascope" to avoid a name-clash with Pyscope, a scoping package on PyPi. See https://sourceforge.net/p/pydatascope/ for the latest code.
