The primary objective of Armadillo is to provide a convenient way to quickly analyze musical sounds on an inexpensive computer without the need for specialized hardware. The development of high speed computers with excellent graphics and high quality audio I/O in the 1990's made this possible. While a number of analysis programs have been available on PC or Macintosh platforms, there are few that are dedicated to the analysis of musical sounds as Armadillo is.
