Dancing About Architecture - Graffiti Jazz | Dirac’s Auto Target Curve | Cutting-Edge Class-D

In this episode of the SoundStage! Audiophile Podcast, hosts Brent Butterworth and Dennis Burger dig into a new album by David Chesky called Graffiti Jazz, a unique and fascinating jazz composition that comes with separate mixes for speakers and headphones. From there they transition into a discussion about Dirac Live’s new Auto Target Curve and how it potentially improves some aspects of room correction, as well as how it could be improved even more. As an aid to new listeners who’ve complained about overuse of terms like hertz and kilohertz without explaining what these mean, we’ve also included a few tone sweeps to illustrate the frequency ranges being discussed. 

To wrap things up, Brent and Dennis dig into two new articles about GaN FETs vs. MOSFETs and what they mean for class-D amplifiers, which gives them a perfect opportunity to dispel some myths about class D.
