The art of music has been of great interest and pleasure for humans, through
all times people have been eager to produce music and the beautiful tones
have amazed us greatly. Today, a wide variety of different music styles
offers a worldwide source of joy to mankind. Lately, the technology of
computers has come to change the society in many different aspects,
introducing new ways of presenting information. Of course, also music
lovers have seen the potential in the new media and have taken action in
developing systems for manipulating and transforming sound into digitised
forms. The ability to store and manipulate sound on computer media opens new
ways of producing and listening to music and speech. However, the process
of converting music from analogue to digital format is not a trivial task.
Advanced mathematical methods and great knowledge in the art of music have
to be combined in a logical way not to change the format of the sound.
Lippold Haken and Kelly Fitz have invented a new analysis/synthesis system
for representing and manipulating sound called the Reassigned Bandwidth-
Enhanced Additive Sound Model. Based on this new model, they also developed
a C++ class library, called Loris, implementing analysis, manipulation, and
synthesis of digitised sound. Apart from the classes and methods provided
in Loris, the library also consists of several interfaces for different
scripting languages and a C-linkable procedural interface.
However, the Loris software only contains access to the new
analysis/synthesis model via the use of programming languages, rather
difficult to understand for music lovers with the lack of programming
skills. The need to present Loris to non-programmers has set the foundation
of this paper. The goal of the thesis is to design and develop a graphical
control application to offer non-programmers the possibility to explore the
functionalities found in Loris in a convenient way.
This work has resulted in a design and implementation of a prototype
application, named Fossa, distributed as part of the Loris project. The
application consists of a graphical interface, which provides
straightforward interaction for the user to exercise several of the
functionalities found in Loris, without introducing the need for any
programming knowledge from the users part. Fossa includes both a graphical
representation of reassigned bandwidth enhanced ...
