IIR Room Tuning | FIR Designer Case Study

Room tuning using IIR filters commonly involves taking live, continuous measurements while adjusting processor settings. Alternatively, it can be an iterative process of measuring and filter adjustment. When FIR-capable amplifiers & processors are involved, room tuning can be optimized further by using the same loudspeaker measurements to develop custom FIR …

Audio FIR Filtering

Although not a new technology, manufacturers are increasingly including FIR filtering in loudspeaker processors and DSP based amplifiers due to the significant increase in performance-versus-cost of microprocessors and DSP hardware. The advantages of FIR filtering include more arbitrary and fine control of a filter’s magnitude and phase characteristics, independent control …
