Sounds we hear..

Finally found time to experiment the use of head-worn binaural earphone CS-10EM with static directional sound in a visual mix. Its very sensitive and highly susceptible to wind noise thus the fluffy beanie helps well in winter as a windjammer. You should notice how it captures the low rumbles coming from the school at a distance and cars driving by. Quiet pre-amps from the R-26 surprised me again here. Mind you these are connected to the Plug-In mic I/O, not the XLR. The XLR connections are much quieter. CS-10EM picks up a full range of 20Hz-20KHz well but I’d only trust the built-in earphone solely for level monitoring and nothing else. And for that, the big gain knob on the R-26 helped greatly to dial in the right level.

For those who are new to Binaural Audio, the next paragraph is a brief introduction about it. If not just skip to the video to hear it for yourself. WAIT!! Before you get to that, grab yourself a good headphone.

Binaural hearing has been emulated in sound laboratories by using mannequin heads with built-in microphones. Except this time, I’m the living breathing head. 🙂 From these signals, human beings can determine characteristics such as inter-aural time and level differences and—based on the listening experience—information about the spatial origin of the sounds being heard. Are they coming from in front or behind, from the left or right, or above or below? This ability to perceive where a sound originates from is referred to as binaural hearing.

Also noted, that GoPro WiFi app does not work well in snow somehow. It was -5ÂşC that morning and the range was somehow drastically reduced. My iPhone sees an connect to the GoPro ad hoc WiFi connection but buttons initiation does not relay well even at this rope length. It could be either the iPhone or GoPro. But phone is warm in my pocket while GoPro is close to the freezing floor.

Oh well, only the sound matters here..
