Our more recent experiments with binaural sound have used a different technique which I'll call headphone surround. It makes sense to develop production techniques that are independent of the reproduction method. (That piece inspired Today's April Fools joke that year, where Evan Davies tried to get the nation to put their hands in front of their face to block out a noise signal, much to our amusement.) Thanks to Internet distribution of programmes, it is now more feasible that different versions of a programme could be delivered, depending on whether headphones or loudspeakers are being used. In 2011 there was a feature on the Today programme about a scientist at Princeton University who is one of the many people working in this area. Another issue is that binaural sound cannot be reproduced over loudspeakers without special processing techniques, which are still developing.

They are not the most portable or inconspicuous of microphones. There are also practical issues with dummy head recording. This mismatch of cues also affects the tonal quality of binaural recordings. It is very difficult to create the impression of sounds coming from in front of your head, partly because of conflicting visual information and partly because of a mismatch between the shape of the dummy head and the shape of your own, which means that the auditory cues are not perfect.
But often the quality of binaural recordings is not yet good enough. Rob da Bank showed some of the classic examples such as the virtual haircut which can be quite spooky to listen to. So why aren't all BBC programmes available in binaural sound? These recording techniques can create great immersive effects when the right demonstrations are used.

R&D's head and torso simulator microphone The brilliantly imaginative interactive drama The Dark House, broadcast in 2002, used miniature microphones placed in the ears of the actors, so you could listen from each of their perspectives. In 2008 the Radio 4 documentary Bravo November, about a Chinook helicopter in the Falklands War, used dummy head recordings from inside the helicopter. Since then there have been occasional experiments with these techniques in BBC programmes. This programme is often played on BBC Radio 4 Extra, so look out for upcoming repeats.
It was a 20 minute play written and performed by Andrew Sachs without a single word of dialogue. The BBC made several pioneering radio dramas using these microphones at the time. These are basically human manikins with microphones placed where the eardrums should be.
In the early 1970s dummy head microphones, like Fritz and the one pictured below, became commercially available. This FAQ page from one of our previous experiments gives a bit more detail about binaural.īinaural sound itself is not a new idea, public performances were transmitted in some form of binaural stereo as far back at 1881. This is as opposed to listening to stereo sound on headphones, as we currently do, which leads to the impression that sounds are all inside your head. Briefly it is a sound production technique that mimics the natural hearing cues created by our head and ears to create the impression of 3D sound when listening on headphones. Whatever the reason, these podcasts-filled with rich narrative storytelling, elaborate audio soundscapes, fascinating phenomena, and good old-fashioned scares-are sure to satisfy listeners seeking out the weird, unexplainable, frightening, or downright horrific.So what is binaural sound? Those of you who read this blog regularly may already be familiar with the concept, as in the last couple of years we've discussed some binaural experiments we've done here. So a creepy podcast could serve as a way to augment Spooky Season, or a way to fully escape from current events. And for the astrologically inclined, Mars and Mercury are also in retrograde, just for fun! While those facts alone might be enough to set the superstitious on edge, there’s also no denying the creeping feeling that our current reality is more disturbing than any tale we’ve ever been told around a campfire.
#Binaural audio spooky full#
On October 31, a blue moon will rise (the first time a full moon has fallen on Halloween in 76 years), and the veil between the spirit world and our own will allegedly thin. “Spooky Season” (also known colloquially as “October”) is, for many, a long-awaited time of the year, and in classic 2020 fashion, this season is packing quite the punch.
