...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.

...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.

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.
