Welcome to audiomeasurements.com
This website is a clearinghouse for audio measurement related information with an emphasis on live audio measurements. The goal is to provide useful information regarding how to measure, verify and tune a sound system, test audio gear to verify proper functionality and to explain the principles of sound system design and optimization as I learn them myself. I am incredibly fortunate to have world class measurement engineers as friends and associates that are willing to share their knowledge.
In the year 2017, measurement software and related hardware is relatively inexpensive and most of the information one needs to advance in this field is available in Bob “6o6” McCarthy’s book, “Sound Systems – Design and Optimization 3rd Edition“. If you buy it via the previous link and it’s not already on sale, use SSD20 as a discount code for a 20% discount at check out.
If you have specific questions about putting together your own measurement rig or how to use it, feel free to contact me.
In general, images on this site can be clicked on to enlarge them. This will be very important when looking at measurement traces as they default to fit the screen within the framework of the website (depending on your browser, screen resolution, device, etc…)
I post about my various measurement experiments and experiences on the BLOG page to the left of the site. Many times I am posting during a tech rehearsal or late at night after a show so I apologize in advance for incomplete posts. If there is something you’re especially interested in and I’ve failed to finish a post on that topic, contact me and I’ll prioritize finishing it. In this case the squeaky wheel gets the most grease.
This site is self sponsored. Consequently decisions about content are mine to make and not based on any outside pressure or influence. It is my goal to maintain a site that is relatively neutral. With that stated, I naturally use and discuss gear I own personally and come across on shows.
This website is and will remain a work in process due to the nature of how the blogging process works. I gather the information as I find it which can happen at any time. Regarding my own measurements, if I see a need for performing a measurement so that I can understand a principle better but don’t have time to perform it immediately, I add a post or page as a place holder. Consequently your patience and understanding are greatly appreciated since some posts are incomplete. I aim to share information that is aimed at helping to build a larger audio measurement community. We have lots of work to do…
Questions, comments and critiques are welcome.
