HTG 354: Going Out of Your Head  

Darin Fong talks about his headphone-virtualization software called Out of Your Head. Topics include a quick summary of head-related transfer functions (HRTFs), how Darin wanted to simulate the effect of listening to a speaker-based stereo system in headphones, how he measures HRTFs in different rooms with different speakers to create presets, and how the software accepts the audio from a media player and applies the selected preset to create a binaural-audio file. We also play a few examples (be sure to listen on headphones to hear the effect!) and discuss various applications and plans for future developments. Plus answers to chatroom questions and more.

HTG 346: Audio Science and Immersive Sound  

With so much more to discuss than we could get to last week, host Scott Wilkinson continues his conversation with Paul Hales, founder of Pro Audio Technology. This week, he explains why he believes that audio science is relatively unrefined, leading to lots of dogma, misinformation, uncertainty, and inconsistency. Next, we dive into immersive-audio systems, including the importance of multiple subs, sophisticated bass management, and speaker directivity. Also, we talk about measuring sound pressure levels, answers to chatroom questions, and more.

Entertainment-technology consultants Geoff Tully and Ron Williams, just back from the 2017 HPA (Hollywood Professional Association) Tech Retreat, talk about some of the main topics of discussion at the event. Paramount among them was high dynamic range (HDR), which Geoff addressed in a presentation advocating HDR with 1080p resolution, a concept that broadcasters embrace. Ron discussed the demo he presented with Grass Valley of a live HDR camera signal shown on an SDR monitor and two HDR monitors, illustrating how HDR actually results in greater perceived detail.
