The use of FIR filters (or finite impulse response filters) has grown in popularity in the live sound world as digital signal processing (DSP) for loudspeakers becomes more and more sophisticated. While not a new technology in itself, these filters provide a powerful tool in system optimization due to their linear phase properties. But what exactly do we mean by “finite impulse response” and how do these filters work? In order to understand digital signal processing better we are going to need to take a step back into our understanding of mathematics and levels of abstraction.
What we perceive as reverb is a combination of two things, called early reflections and late reflections. Early reflections are the first reflections of the source sound that make it back to our ear; they are the reflections that travel out, reflect off of something once, and head back. Late reflections are the reflections that spend time bouncing off of multiple surfaces before returning to our ear. Because we experience such a large number of reflections arriving at our ears so closely together, we do not hear them as individual, echoed copies – instead, we get the smooth sound of reverberation.
The wonderful people who make up our industry are not easily replaced by someone deemed “unskilled” by a large corporation. We have a wealth of knowledge that is often built up from years of experience and dedication to our craft. I’m hoping in the future labor companies will be more willing to split bids with other companies in order to properly fill calls for clients. I’m also hoping companies like Uber Works don’t continue to devalue our labor. You can’t penny and dime our skillsets or take a commission on an hourly rate. A low-balling bid war during this time wouldn’t just set back rates; it would push so many more away from an industry that they love.
