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.
