This bonus podcast is a generated discussion that took a rather unexpected turn, which I found interesting so we have published it as a bonus episode. Charged with generating a debate about last week's podcast, the debate quickly moved to a rather more philosophical discussion about the nature of high-fidelity audio itself. Do we value the purest signal in terms of freedom from noise, or do we instead seek to create a 3-D sound picture, majoring on placement and position? The move from mono to stereo represented the first major development into spatial audio, but modern object-based immersive audio take this to a whole new level. Listen and enjoy!
