This paper describes a new rapid development environment for digital audio applications and computer instruments, AIDE (Audio Instrument Development Environment). The system is designed to help users build signal processing applications for use in music, multimedia and sound design. Based on a graphical patching principle, this system generates software using the V and Sound Object libraries. These provide the graphical interface/application framework and sound processing elements, respectively, for standalone programmes generated by AIDE. It is envisaged that the system will also generate application components in addition to stand-alone programs. The paper outlines in some detail the elements involved in the software. It discusses how the system is aimed at different types of users with different levels of interaction. The paper concludes with an overview of the typical application development cycle using the system.

The Csoundo library combines the sound compiler Csound with Processing, a java-based programming language for visual applets. The combination of the two provides a framework for the rapid development of interactive audio-visual applications. Csound and Processing have recently been ported to the Android platform so these languages may now be used to develop applications directly for Android devices. However, at present, Csound for Android has only been implemented with basic Android Graphical User Interface(GUI) elements while Processing for Android lacks support for external libraries, including its established audio libraries. Csoundo for Android bridges the gap between the two languages and allows developers to rapidly build interactive audio applications without having to be concerned about the inner-workings of Android development.
