libxmp is a library that renders module files to PCM data. xmp is a module player for Unix-like systems, based on libxmp, that plays over 90 mainstream and obscure module formats from Amiga, Atari, Acorn, Apple IIgs and PC, including Protracker (MOD), Scream Tracker 3 (S3M), Fast Tracker II (XM) and Impulse Tracker (IT) files.

The GUIDOLib provides a powerful engine for the graphic rendering of music scores, based on the Guido Music Notation format. It supports Linux, Mac OS X, Windows, Android and iOS operating systems. A Java JNI interface is available as well as a Javascript version of the library. A Web API has also been designed, allowing to deploy the engine as a Web service.

VSTGUI is a cross platform C++ library mainly for developing user interfaces for audio plug-ins (VST, AudioUnit, AAX, RTAS, etc).

A netease cloud music-based UI, using wanandroid API development accord with Google Material Desgin reading class open-source projects. Kotlin && Netease cloud music Ui && Retrofit2 + RxJava2 + Room + MVVM-databinding && Wanandroid API. NetEase Cloud Music was officially released on April 23, 2013. It is an online music product that focuses on discovery and sharing and has a strong social use. I believe that everyone who has used it will know that the experience it gives is excellent. The daily content pushed by the dry goods concentration camp, including a picture of a girl every day, related Android, IOS and other dry goods. It is updated every day after 12:30, because the content is not updated on weekends, so the content is cached for three days if it is not available on the Internet.

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.

The Environment State Virtual Sensors for Android is a library that allows recognition of environmental scenarios in which an Android device can be found. The basic scenarios types are: Motion states, Noise states, Proximity state, ringer-mode state.

Java Tiny Gfx Library (JTGL) is a graphic fundation framework (a graphics/gaming api) that will allow easy deployment/porting of applications/games on many environments: J2SE,J2ME/MIDP(Nokia,Siemens,BlackBerry),SuperWaba(Palm,PPC,Symbian),ExEn,DoJa,etc..

JUCE is a C++ toolkit for building cross-platform applications on PC/Mac/Linux/iOS/Android. Particularly good for complex, customised GUIs and audio/midi processing, it also includes a vast range of classes to help with all your day-to-day programming tasks.

LibBWEntrainment is a Free and Open Source Brainwave Entrainment Library for Java. *** It is not a standalone application. *** The library is very flexible, allowing different types of renderers (isochronic, binaural, ...) as well as multiple output devices (speakers, file, socket or even screen), and it can easily be ported to other languages because it doesn't use any proprietary Java feature. Current features: -Javadoc and examples -Extremely lightweight, yet flexible -Easy to use -XML Presets -Multiple Entrainment Tracks -Looping -Isochronic rendering -Output to PC and Android -Output to MP3/FLAC/Wav file -Output to raw Stream Compared to my old LibBinaural, this is twice as fast and much more flexible. A project using this library is available here https://sourceforge.net/projects/isochronic/.

Scalable Language API (SLAPI) The most comprehensive architecture for conversational natural-language applications including speech recognition/synthesis, semantics, & machine translation. Used on Android & other mobile app platforms.
