MARSYAS is an open source audio processing framework with specific emphasis on building music
information retrieval systems. It has been under development since 1998 and has been used for a va-
riety of projects in both academia and industry. In this chapter, the software architecture of Marsyas
will be described. The goal is to highlight design challenges and solutions that are relevant to any MIR
software.
IntroductIon
ing. It is likely that in the near future anyone will
be able to digitally access all of recorded music
in human history. In order to efficiently interact
with the rapidly growing collections of digitally
available music it is necessary to develop tools
that have some understanding of the actual musi-
cal content. Music information retrieval (MIR)
is an emerging research area that deals with all
aspects of organizing and extracting information
from music signals.
Advances in technology have always transformed
music. Examples of technologies that transformed
the way music was produced, distributed and
consumed include musical instruments, music
notation, recording and more recently digital
music storage and distribution. Recently portable
digital music players have become a familiar sight
and online music sales have been steadily increas-
