ArtemiS II

Dates and Times

April 1-2, September 23-24, 2008
Course is from 8:30 AM to 4:00 PM (lunch is provided each day)

Prerequisite

ArtemiS I Seminar or authorization by instructor.

Seminar Objectives

(Participants are encouraged to bring their own data files, for use in addition to those provided for the course.)

In general, this seminar develops the use of ArtemiS as an analytical extension of human perception for sound quality and vibration analysis in both an acoustic and a multichannel acoustic-plus-vibration context. How to select and apply conventional metrics and psychoacoustic metrics in situation-specific ways, based on listening to the data, is covered with hands-on participation. Synthetic signal generation, import-export operations, and use of the ArtemiS Editor are included.

Specifically, the seminar addresses the operation of functions found in the following ArtemiS Tool Packs: ATP 2 Psychoacoustics, ATP 3 Signature Analysis, ATP 4 Octave Analysis, ATP 10 Generator and Editor, and ATP 12 Database.

Course documentation includes printed material plus comprehensive Powerpoint presentations and a library of worked ArtemiS example Projects. A large, categorized selection of data files is included. Course materials constitute a major reference resource for ongoing use in laboratory libraries. Exercises will be interspersed throughout the course to provide individuals hands-on work.
