HTG 367: Immersive Audio for VR  

Audio engineer Bob Schulein talks about his work combining immersive binaural audio with virtual reality. Topics include the difference between VR for gaming and music recordings, different techniques for capturing binaural sound, head tracking, combining immersive audio with 3D video, Bob's latest project recording a bluegrass band in binaural audio and 3D video, binaural recordings from the artist's perspective, binaural playback with speakers, answers to chat-room questions, and more. We also play several clips with binaural audio, which can only be heard in the video versions of the podcast; the audio-only MP3 is mono, so no binaural effects can be heard in that case.
