IASA 2018 Annual Conference

This tutorial explores all aspects concerning the pre-emphasis and de-emphasis that may be applied to a modulated groove. The characteristics, in terms of frequency vs. amplitude response, of the different cutting and replaying processes (mechanical, electromagnetic, optical, etc.) are comprehensively exposed. The goal is to answer most of the where, why, and how questions, to build a solid background that will help choosing and applying the correct de-emphasis, in both the analog and the digital domains.

The presentation, although supported by a number of sound examples, is very technical, and easier to understand for those who are already familiar with this topic, or who have attended my presentation in the Expert Transfer Techniques series of last year.
