The Course

AFMG® SysTune is a real-time audio measurement and analysis software from AFMG® Technologies GmbH. It provides the user with powerful tools to measure and tune their live sound events by means of real-time determination of impulse response. The tool is equally helpful for installed systems of all extents.

This online course covers this measurement and tuning tool and clarifies the background needed to use it efficiently.

A considerable part of the course treats the practical side of using AFMG® SysTune in real-world live events.

Course Objectives

Upon completion of the course, the students will

1. be exposed to the needed background in acoustics and digital signal processing for using AFMG® SysTune,
2. learn how to set-up the measurement system and calibrate the measurement chain,
3. be familiar with the different test signals and how to make the right decision about using any one of them,
4. understand how to carry out measurements in AFMG® SysTune,
5. gain better understanding of using AFMG® SysTune through exploring several real-world cases, and
6. be trained in interpreting the measurement results and extracting conclusions out of them.

For Whom Is the Course?

The course is designed for those, who are involved in setting up, testing, commissioning, measuring and real-time tuning of sound reinforcement systems.

Previous knowledge and experience with acoustical measurements would be helpful but are not prerequisites for the course. Students, however, are assumed to have a reasonable level of engineering general knowledge and to understand the basic definitions and terminology.


Direct E-Mail Support

Each course student shall have access to direct and personal e-mail support for the course curriculum for ninety days from the day of enrollment or releasing course material online, whichever is later.

During this period, the student can send his/her questions to the instructor, and shall receive an answer from the instructor within 48 hours at latest.

The e-mail support can be extended to one year against extra charge.


Testing and Certification

After each lecture, students shall have the chance to take a number of quizzes to test their progress with the course topics.

At the end of the course, there shall be a final set of quizzes to test the students' knowledge of the entire course and how far the met the objectives.

Certificates for this course are issued by in cooperation with AFMG® Technologies GmbH. A certificate of successful completion shall be issued to the students, whose overall score based on all quizzes in the course including the final set is 75% or better.
