    wavesurfer.js

    wavesurfer.js

    Navigable waveform built on Web Audio and Canvas

    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.

    MusicDNA

    Experience your favorite music in a unique way

    MusicDNA is a music player unlike any other. It is an Android music player that renders beautiful DNA (visualization) of the currently playing music. It does this through the use of the Visualizer Class, and is inspired by paullewis's music-dna. It uses the FFT Data supplied by the Visualizer class of Android , calculating the Amplitude at that exact moment and using this to plot the DNA. MusicDNA fuses the functionality of traditional music players with stunning visualizations. In this way it captivates not only the sense of hearing but the sense of sight as well. MusicDNA's player allows for playing both local music as well as streamed music from SoundCloud.

    EZAudio

    EZAudio

    An iOS and macOS audio visualization framework

    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 pure C. EZAudio was designed to work transparently across all iOS and OSX devices. This means one universal API whether you're building for Mac or iOS. For instance, under the hood an EZAudioPlot knows that it will subclass a UIView for iOS or an NSView for OSX and the EZMicrophone knows to build on top of the RemoteIO AudioUnit for iOS, but defaults to the system defaults for input and output for OSX.
