Network control brings new possibilities to user interaction with DSP devices. One important area is to offer real-time control of filter shapes (center frequency, Q, and gain) by changing filter coefficients in real time. Textbook solutions to DSP filter problems rarely consider such dynamic situations. This paper presents observations on implementing real-time control of DSP. The work explores the update rate and granularity required to achieve perceptually smooth, real-time control.
