The Very First  step to Sound Design is choosing the right components. Once the physical components of a sound system have been properly installed, then it's time to begin the process of "tuning" the system for optimum matching with the acoustic characteristics of the space as well as the speakers used. 

If the system is not properly tuned then the full potential of all the carefully selected components will not be realized. 

Post-installation tuning can be broadly divided into two types: speaker tuning, which is processing specifically aimed at maximizing the performance of the speakers themselves, and room tuning, which addresses the acoustic characteristics of the space in which the sound system will function.  

What’s the goal of tuning a system? To have the same sound everywhere. That means having the same level, same frequency response, and same intelligibility in every single seat.

Is that attainable? No. Our atmosphere is a harsh place for sound waves. But do we strive for faithful delivery to all ears? Absolutely. Tuning can be objectively measured. We have tools that we can use to measure exactly how close we are to achieving our goal, and therefore, declare success. With software and hardware such as SIM, Smaart, Easera, and SATLive, we can perform a transfer function to measure relative level, delay/phase, and frequency response. Toning, in contrast, is a subjective process.
