Once we’ve finished tuning the system, we often use music to evaluate the results. But how do we know what’s actually been recorded? How big is the actual stage? Where are the instruments and vocals actually located?
World renown recording and mastering engineer, Bob Katz will explain how these recording attributes are captured in the recording or synthesized in the mix so we will be better able to assess the final performance of systems we build and tune. Bob will explain what sonic properties are described by words like “fat”, “thin”, “edgy” and others. He will also cover loudness and level setting in mixing and mastering to explain why some recordings and streams sound louder than others. Vertical Divider

Modern and advanced tuning processes now include two additional advanced processes--
spatial averaging techniques and phase measurements. Learn how to make these measurements, what they mean and how to incorporate them into your analysis and tuning process. Concepts will be presented as models to build a foundational understanding. Vertical Divider

Building on the foundational
information presented in Session 3, Session 4 will provide a system tuning example and a process in real time. This process will incorporate spatial average measurements and phase analysis so attendees will see a real-world example of how to make these measurements and how to use them to enhance system performance and speed up the process of system optimization. |
Session 1 & 2 (Combined Double length with intermission)
Course Name: Music Recording & Production
Instructor: Mastering engineer, Bob Katz
Course Details
Once we’ve designed and installed the reproduction system, adjusted and tuned it, we always evaluate the performance using music. Learn how staging and imaging are recorded or created in the final mix. Bob will also talk about the frequency components of various instruments and vocals and about what it means when someone refers to the sound as “fat” or “thin”, “muddy”, “sweet”, “edgy” and so on. Additionally, if you’re confused about recording levels, why some recordings or streams sound much louder than others and what that means for other aspects of performance and system level setting, Bob will fill us in.
This course is a unique opportunity to learn about how important aspects of recordings are created from the guy who literally wrote the book and who has been making many of the world’s best audiophile quality recordings for nearly 50 years.
What you will learn
● How staging and imaging are captured and/or synthesized in the recording and mastering process.
● What frequencies instruments and vocals are comprised of to facilitate subjective system analysis.
● How recording levels contribute to our perception of more than just how loud a tracks seems to sound.

Who is Bob Katz?
Since 1972, Bob has been recording and mastering audio and video for television and for audio playback of recorded media (records, tapes, CDs and files for streaming. In 1979 Bob moved from Connecticut where he had been the Supervisor of the Connecticut Public Television Network to launch his career in NYC in recording for records, radio and TV. Since that launch, Bob has produced and mastered three Grammy-winning CDs, produced many recordings that have won “Recording of the Month” from Stereophile Magazine including “The Best Audiophile Recording Ever Made”. Bob has invented and created audio hardware, software, contributed to accepted recording standards, designed, built and retrofitted recording studios. Additionally, Bob has written to books regarded as required reading for anyone producing, mixing or mastering recordings: Mastering Audio: The Art and the Science, now in its third edition, and iTunes Music: Mastering High Resolution Audio Delivery. |
The list of recordings to which Bob has contributed or produced in their entirety is much too long to include here. Chances are, if you’ve ever competed in a car audio sound quality contest, used one of the sanctioned competition CDs or had your own copy of “The Ultimate Demonstration Disc”, Bob has contributed already to your enjoyment or your understanding of your craft through his work.

Session 3
Course Name: Advanced Measurements and Analysis Instructor: Andy Wehmeyer Course Details While engineers in labs have been making advanced measurements for a long time, recent upgrades in hardware and software performance in affordable PCs have made it possible for even car audio techs to incorporate laboratory processes into retail system optimization. |
In this course, we’ll explain impulse response measurements, spatial average measurements using microphone arrays and the measurement of speaker and system phase directly. Learn how to make these measurements and what they mean so you can incorporate them into a tuning process that will provide even better system performance, reliably and in less time.
What you will learn
● The course covers impulse response measurements, which contain both frequency response and phase data necessary for
advanced tuning.
● Learn how to make a spatially averaged measurement and what it contains. Learn why you ought to incorporate this in an
advanced tuning process.
● The course will provide a foundational understanding of phase and how it contributes to system performance. Learn what
crossovers and EQ, reflections and delays do to phase and how to identify these components in a phase measurement.

Session 4
Course Name: Advance Data Tuning
Instructor: Mark Eldridge
Course Details
A hands-on demo of how to make advanced measurements, collect and use the acquired data. Measuring frequency response and phase simultaneously with a microphone array and a timing microphone will be demonstrated. Learn how to incorporate phase measurements into real-time optimization of crossovers and final system imaging performance. See real world examples of the influence of reflections and speaker placement on measurement data. This session will tie up the two previous sessions by providing the “how to” so you can more easily incorporate advanced data and final subjective evaluation of system performance into your tuning process.
What you will learn
● How to make advanced frequency response and phase measurements
● How to incorporate advanced measurements and data into a live tuning process.
● How these processes affect our subjective analysis using music.
