T9 - How I Does Filters: An Uneducated Person’s Way to Design Highly Regarded Digital Equalizers and Filters

Peter Eastty, Oxford Digital Limited - Oxfordshire, UK

Much has been written in many learned papers about the design of audio filters and equalizers, this is NOT another one of those. The presenter is a bear of little brain and has over the years had to reduce the subject of digital filtering into bite-sized lumps containing a number of simple recipes that have got him through most of his professional life. Complete practical implementations of high pass and low pass multi-order filters, bell (or presence) filters, and shelving filters including the infrequently seen higher order types. The tutorial is designed for the complete novice, it is light on mathematics and heavy on explanation and visualization—even so, the provided code works and can be put to practical use.

Many of the sessions not mentioned here will be of interest to students, depending on their specialization and progress. Especially all Tutorials, Master Classes, the Live Sound Seminars, and many of the Workshops have much to offer.
