The Audiophiles Guide
The Audiophile's Guide podcast is your invitation into the world of high-end audio, and connecting with me, Paul McGowan—a 50-year veteran in the art and science of sound and the co-founder and CEO of PS Audio. We do kind of a mind meld between me and our technologically connected hosts. Each episode is a fresh, no-nonsense exploration of how to bring music to life in your home, drawn from my decades of hands-on experience designing the gear that makes it happen.

PCM audio vs. PDM and DSD
Pulse code or pulse density? In this episode, we dig into PCM, PDM, and DSD—three very different ways of turning digital bits into sound. Based on insights from The Audiophile’s Guide, the discussion unpacks how each format works, how they shape what we hear, and why it matters for both streaming and physical media. From classic Red Book CDs to high-res DSD files, it’s a deep dive into the digital languages behind the music—and what your DAC has to say about it.
