John Vanderkooy, Distinguished Professor Emeritus, Department of Physics and Astronomy, University of Waterloo, Waterloo, Ontario, Canada, will preview his thoughts on Unwinding Coupling Capacitors.Audio program material has typically gone through many high-pass coupling capacitors before it is finally committed to a storage or playback medium such as CD or streaming audio. This, together with the typical low-frequency characteristics of microphones, playback electronics and loudspeakers, causes a cumulative phase behavior that seriously distorts the wave shape of low-frequency waveforms. The human ear has some sensitivity to such distortion, and this paper devotes itself to a study and mitigation of this phenomenon. John is interested if some of our group can help with finding appropriate signals to demonstrate (or not) the significance of LF phase distortion. John is prepared to share code and details for Matlab or open source Octave. {Contact John Vanderkooy at [email protected]} Q&A follows the presentation.
