Open-source alternatives to Circular Audio Wave

BlenderGIS is an addon for Blender that provides a suite of tools for importing, georeferencing, and rendering geographic data and terrain meshes. It functions as a 3D terrain generator and geographic data importer, enabling the creation of three-dimensional surfaces from elevation models, contour lines, and topographic textures. The project distinguishes itself through its ability to fetch basemaps, building footprints, and street data directly from web services into the 3D environment. It includes a georeferencing toolset to align coordinates and virtual cameras using spatial reference syst

PlotJuggler is an interactive time series visualization tool that loads, streams, and renders large datasets using hardware-accelerated OpenGL graphics. It functions as a multi-format data loader, supporting file formats such as CSV, ULog, and ROS bags, and also serves as a live data stream viewer that subscribes to real-time sources via MQTT, WebSockets, ZeroMQ, and UDP. The tool distinguishes itself through a plugin-based extensibility platform that allows users to add custom data sources, file formats, and processing capabilities. It includes a Lua scripting engine for creating custom data

Howler.js is a JavaScript library that provides a unified interface for managing audio playback across web browsers. It functions as a cross-browser audio engine, abstracting complex browser audio APIs into a consistent developer experience while ensuring reliable performance through automatic fallback mechanisms. The library distinguishes itself by offering specialized tools for spatial audio and efficient asset management. It includes a spatial audio framework that maps three-dimensional vectors to audio nodes for immersive sound positioning, alongside an audio sprite manager that allows de

Circular visualization in R

wavesurfer.js is a WebAudio playback library and interactive waveform visualizer that renders audio data onto an HTML5 canvas. It enables users to see and navigate sound files through a visual representation of audio peaks, allowing for direct seeking and playback control within a web browser. The project is distinguished by its flexible rendering model, which can use precomputed peak data to display waveforms without downloading or decoding the full audio file. It utilizes a plugin-based extension model to integrate advanced tools such as spectrograms, interactive audio timelines, and real-t

Sound.js

audiojs is a drop-in javascript library that allows HTML5's tag to be used anywhere. It uses native where available and falls back to an invisible flash player to emulate it for other browsers. It also serves a consistent html player UI to all browsers which can be styled used standard css.

A library for audio and music analysis, feature extraction.

Librosa is a Python audio analysis library and digital signal processing framework. It functions as a feature extraction suite and music information retrieval tool designed to analyze the structural and sonic characteristics of audio signals. The library provides specialized capabilities for music analysis, including dynamic tempo tracking to identify rhythmic pulses and spectral feature extraction to compute harmonic spectra, chroma variants, and onset points. It also serves as a time-series audio processor for synchronizing audio streams. The system covers a broad range of audio processing

Magenta.js is a collection of TypeScript libraries for doing inference with pre-trained Magenta models. All libraries are published as npm packages. More information and example applications can be found at g.co/magenta/js.

Tippecanoe is a command-line tool used to generate optimized vector tiles for web maps. It converts large-scale geospatial datasets, including GeoJSON, CSV, and Geobuf files, into binary vector tiles or MBTiles SQLite databases. The project is designed to maintain map performance and visual quality across different zoom levels. It achieves this through geospatial data downsampling, which includes simplifying geometries and thinning point density to prevent tile overcrowding and keep tile sizes within specific limits. The tool provides extensive data transformation capabilities, such as attri

Audio feature extraction for JavaScript.

MIDI.js is a JavaScript library for playing MIDI files and triggering musical notes within web browsers. It functions as a web MIDI library and soundfont audio synthesizer, providing the core engines necessary to render instrument sounds for multiple simultaneous tracks. The project includes a specialized MIDI-to-visual sync engine that interpolates musical events into continuous animation loops to synchronize visuals with audio playback. It also provides a soundfont code generator to convert audio instrument files into base64 code for direct browser consumption. The library covers MIDI file

The purpose of ChordMark is to provide the easiest possible way to write accurate chord charts, e.g., text-based song transcriptions with lyrics and chords. ChordMark charts are usable by all musicians, whether they sing or not, whether they already know the song or not, and whether the song…
