Open Source SynchroPhasor PMU
The GridTrak Open Source SynchroPhasor PMU Project provides resources that enable you to build your own SynchroPhasor sensor for use with the openPDC project, research, development, or electric grid observation.
frequency gridtrak gtospmu open-source-pmu openpdc openpgclubber - Application of music theory in audio reactive visualizations
This small js library listens to audio sources and extracts the underlying rhythmic information. The linear frequency energies are converted into midi notes which music theory suggests to be a better segregation for music audio. A set of meaningful measurements are produced in a form suitable for direct use in webgl shaders, or any other context. This simple flow provides a powerful framework for the rapid development of awesome audio reactive visualisations.

For the given WebAudio AnalyserNode, determine the average signal (0 .. 1) between two frequency ranges in Hz. This can be useful for audio visualization on a certain spectrum of the frequency graph.The frequency is assumed to be in byte data, though you can use the floatData entry point to get around this.

An implementation of Coromode and Muthukrishnan's Count-Min sketch data structure for JavaScript. The count-min sketch is basically a high powered generalization of the bloom filter. While a bloom filter gives an efficient way to approximate membership of a set, a count-min sketch can give approximate data about the relative frequency of items in the set. Creates a count-min sketch data structure.

Detects the pitch of a signal using the autocorrelation method. Detects the pitch of signal by computing the period by autocorrelation.

Abacus let you count item frequencies in big datasets with a fixed amount of memory. Unlike a regular counter it trades off accuracy for memory. This is useful for particular tasks, for example in NLP/ML related tasks you might want to count millions of items however approximate counts are good enough.

react-slider-kit is going to be a comprehensive solution to slider feature in react. This component was originally inspired by dribble concept design The Range Slider Component. React-Slider-Kit is bundled as a combination of multiple components, and by default the single slider is imported.

The goal of this library is to provide handy features that didn't make it to the Swift standard library (yet) due to many different reasons. Those could be that the Swift community wants to keep the standard library clean and manageable or simply hasn't finished discussion on a specific feature yet. If you like this, please also checkout HandyUIKit for handy UI features that we feel should have been part of the UIKit frameworks in the first place.
