...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.

JUDI is a framework for large-scale seismic modeling and inversion and is designed to enable rapid translations of algorithms to fast and efficient code that scales to industry-size 3D problems. The focus of the package lies on seismic modeling as well as PDE-constrained optimization such as full-waveform inversion (FWI) and imaging (LS-RTM). Wave equations in JUDI are solved with Devito, a Python domain-specific language for automated finite-difference (FD) computations. JUDI's modeling operators can also be used as layers in (convolutional) neural networks to implement physics-augmented deep learning algorithms thanks to its implementation of ChainRules's rrule for the linear operators representing the discre wave equation.

NEW V3 version with RTC and buzzer (require V3+ ECG Logger Viewer application) The ECG Logger project is a Wearable Cardio Monitor for Long-Term (up to 24h) ECG Data Acquisition and Analysis (aka Holter) with an ECG live (real-time) mode. This project provides a very low-cost open-source "Hardware and Software" for a Cardiac Rhythmic Holter. The hardware has been made very simple and is based on an Arduino Nano micro-controller with boards for SD card mass-storage, instrumentation...

An iOS and macOS audio visualization framework built upon Core Audio useful for anyone doing real-time, low-latency audio processing and visualizations. I've designed six audio components and two interface components to allow you to immediately get your hands dirty recording, playing, and visualizing audio data. These components simply plug into each other and build on top of the high-performance, low-latency AudioUnits API and give you an easy to use API written in Objective-C instead of...

...Summary displays starts with the choice of a geospatial map-view or annunciator panel, both with unique visualizations for across-the-room visualizations fit for a PQ operations center. Drill-downs are in place for various statistics and guide users all the way down to the waveform level. This version consist of a few proof-of-concept applications of applying event severity and trend values to heatmap displays—giving the PQ engineers a wide-area status of PQ for quick interpretation. Data quality has been added so users can quickly see when meters are providing incomplete or invalid data. This dashboard currently accepts power quality data from COMTRADE and PQDIF standard file formats. ...

...Slider controls let the user select any coefficient or sample from any of several transforms, which can then be plotted to either axis of a 2D histogram (scatterplot). Within the waveform space, cursor-based controls let the user select subregions of the waveform space or individual waveforms to view. The user may cluster waveforms manually or via one of several popular clustering programs. The classification along with waveform properties (width, etc.) can be saved to disk in simple text files. WaveSorter is written in C++, utilizes the GNU Scientific Library for all computation, and is highly parallelized; on modern hardware it can handle files containing several 100,000s of waveforms per channel with almost no noticeable loss in GUI fluidity and <1sec lags for files with >1,000,000 waveforms per channel. ...

Waveform viewer. Inspired by 'gtkwave' and 'Dancer2' (Denso proprietary tool). Used primarily for embedded software development, this tool allows for visual signal comparison and analysis. Gaming style mouse + keyboard makes for fast/fun use.

Web based visualizations of data from CPAP/APAP machines, such as the Philips Respironics System One

Magstripper is a magnetic card reader and decoder that takes raw waveform information from a magnetic audio head (soldered directly to a mono audio jack) and processes it via a mic input. It also includes a multi-user door lock access control system.

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.

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.

...Trans-Scribe will provide users with an interface for transcribing .wav audio speech files in any language and creating documents that display, publish, or export the waveform along with transcriptions.
