Applications of Inverse Filtering to the Optimization of Professional Loudspeaker Systems
The application of FIR filter technology to implement Inverse Filtering into a Professional Loudspeakers Systems nowadays is easier and more affordable because of the latest development of DSP technology and also because of the existence of a new DSP platform dedicated to the end user. This paper presents an analysis, based on real world examples, of a possible methodology that can be used in order to synthesize an appropriate Inverse Filter both to process a single driver, from a Time Domain perspective in a multi-way system, and to process the output pass-band from of a multi-way system for phase linearization. The analysis and discussion of results for some applications will be shown through real world test and measurements.
