In this paper we present the EASY (Electro-Acoustic muSic analYsis) Toolbox software system for assisting electro-acoustic music analysis. The primary aims of the system are to present perceptually relevant features and audio descriptors via visual designs to gain more insight into electro-acoustic music works and provide easy-touse "click-and-go" software interface paradigms for practical use of the system by non-experts and experts alike. The development of the EASY system exploits MIR techniques with particular emphasis on the electroacoustic music repertoire - musical pieces that concentrate on timbral dimensions rather than traditional elements such as pitch, melody, harmony, and rhythm. The project was mainly inspired by the lack of software tools available for aiding electro-acoustic music analysis. The system's frameworks, feature analysis algorithms, along with the initial analyses of pieces are presented here.
