You’ve done everything you can think of to keep the levels constant. You’ve added amps. You‘ve moved speakers. Still, the amount of reverberation in your worship space makes intelligibility a real challenge. Then, of course, there’s background noise and feedback. Believe it or not, there may be a simple solution to combating these sound quality issues. Three letters. DSP.
Whether audience members are in a theatre, an auditorium, or a church like yours, they have high expectations about sound quality. So if you’re curious about the ability of DSPs to provide the remedy, read on. We’ll cover some of the basics:
• DSP – Digital Signal Processing
• Signs and Symptoms: When It Can Help
• Types of DSPs
• Practical Applications
In this blogpost, Shure’s Gino Sigismondi is here to tell us what Digital Signal Processors can and can’t do. We also recruited expert Jim Brown of Audio Systems Group to share his vast real world experiences.
How They Work
Digital Signal Processing converts signals from real world sources (usually in analog form) into digital data that can then be analyzed. Analysis is performed in digital form because once a signal has been reduced to numbers, its components can be isolated and manipulated in more detail than in analog form.
When the DSP has finished its work, the digital data can be turned back into an analog signal with improved quality. A DSP can filter noise from a signal, amplify frequencies and suppress others.
