FIR Filters

This article was originally written in 2014, and it was published by Synergistic Audio Concepts, the association of professional audio practitioners and designers.  We in the pro audio community have for many years pushed to bring a powerful digital processing tool called FIR (finite impulse response) filters to the field as we are tuning systems for our clients.  Now, finally, with the right measurement tools and new, powerful software, we are able to accomplish things we were never able to do before, and, more importantly, we can achieve a level of quality and realism previously unattainable in tuning installed systems. As you read this article, you may well find that many of the terms and concepts are “over your head,” however, the important take-away should be that having your system tuned by someone with the skill and equipment to implement this sort of advanced digital processing can and will produce amazing results.

10 Silly Things Churches Do With Loudspeakers

This article is adapted from a presentation originally given by Robert Bernecker at

Techxplosion in Tampa Florida.  It is a look at common mistakes that we have observed at

many churches, and its often light-hearted approach to frequently repeated mistakes makes

for enjoyable reading. 

We believe that the information in this article is also a great primer on why churches should seek outside expertise when considering audio and video system changes or upgrades.  In the long run, steering clear of easily-avoidable mistakes saves the church more money than the cost of a qualified designer.

Reverberation in Churches

This article is intended to convey a basic understanding of the concepts and challenges that are involved in the acoustics of a worship space.  We hope that it is an easy read, and that it will equip you with the knowledge needed to know when a supposed “expert” is telling you things that are not necessarily correct.  As a result, you will be able to better work with your acoustic consultant as he or she develops a design for your space.

LCR Sound Systems - What Are the Benefits?

The term “LCR System” is often thrown about when church sound systems are discussed.  However, the term is more often used incorrectly than correctly!  SEFI Consulting has done a number of LCR systems, and we are big proponents of LCR designs when they are done correctly.  This article discusses the characteristics of a true LCR system, explains the benefits and technical challenges, and explores the costs.  This is another article that may provoke questions.  Feel free to contact us with your questions, ideas, or inquiries.
