Maxim is designed to make it easier to program cross platform audio for desktops amd mobile platforms. It provides a single API for building complex audio applications on Android, iOS and the Desktop, using the WebAudioAPI in combination with traditional Java approaches for compatibility.
It's a work in progress, but vastly simplifies the process of getting started writing audio and music software for mobile platforms
