dual-channel measurements / Time domain vs. – Fundamental Measurement Concepts: Single channel vs. Topics Covered Include (but not limited to): – A detailed and hands-on (as possible) examination of the requirements for configuring and controlling a Smaart measurement rig. – A systematic breakdown of how they are realized in Smaart measurement software – A fundamental description of the measurement concepts involved in dual-channel FFT based analysis (as used in our industry) The Operator Fundamentals Class provides: Throughout this alignment practicum, the session seeks to reinforce the necessary collaboration of measurement and listening skills
It presents the use of Smaart in a methodical process of evaluating and adjusting the individual system components, and the subsequent combination of multiple subsystems into a multi-channel / distributed sound system. The second & third day involves a hands-on practicum focusing on the implementation of the information presented in the first days. The first day of class are primarily a classroom lecture and lab format, relying heavily on in-class measurements. This course focuses on providing the attendee with a functional knowledge of how Smaart operates as a tool before expanding to the application of that tool in sound system engineering, and as much as possible, examines data interpretation as much as acquisition. This course begins with an overview of both the general system measurement theory involved as well as the operational context in which Smaart is used, namely in Sound System Engineering and Alignment.
Special attention is paid throughout the course to the subject of how to make valid and useful measurements. The Smaart Operator Fundamentals covers the fundamentals of setting up a Smaart measurement rig and using Smaart to make basic RTA, Spectrograph, Transfer Function and Impulse Response measurements. If you have any questions concerning course prerequisites, please do not hesitate to contact the listed Smaart instructor prior to registration.
