![]() ![]() That’s it! You are now recording binaural audio. A popular method in nature recordings is to put a tree trunk between mics. Ideally, this object will replicate the geometry of a human head. Place a dense object in the space between mics. These differences create the 3-D interpretation by your brain. Using this distance is crucial for creating the subtle differences in arrival time and volume. This is the average distance between human ears. Space your microphones 7” (18cm) apart from each other. You will need one microphone for each “ear.” Since the internal microphones on handheld field recorders are not spaced properly for binaural recordings, you’ll need to purchase external microphones. Follow these steps to achieve these results. In order to replicate human hearing and create a 3-D soundscape, binaural recordings must emulate the distance between our ears and the geometry of our heads. Based on the difference in time and loudness, it tells us where the sound originated from! This directional information is called sound localization.īinaural recordings attempt to replicate these differences between right and left channel audio. The real magic occurs when our brain receives this information. These subtle differences in time received and intensity are called interaural time and level differences respectively. One ear will hear the sound first and it will be more intense (louder). This additional distance will cause each ear to hear the sound slightly differently. How it works in real life:Ī sound that originates on our right side must travel further to reach our left ear. This feat is possible thanks to the natural spacing of our ears, our heads, and interaural differences in time and intensity. Within milliseconds of sound waves entering our ear, we already know its pitch, location, and what produced them. The three combine to produce instant feedback in response to sound. The relationship between our ears, head and brain is fascinating. To fully understand how this works, we must do some research on human hearing. That’s because binaural recordings replicate what environments sound like to humans. It is as if you are really standing in the recorded environment. You can hear sounds all around you and can pinpoint their location. Listening to binaural audio creates a 3-D landscape of sound inside your head.

It’s used in everything from ASMR videos to music claiming “life-changing” abilities. Output: 3.“Binaural” is a term that gets thrown around a lot in our industry. The microphone has two (2) Male 3-pin XLR outputs, one for each ear.ĭimensions: 7.5" x 4.5" x 4.5" | 190mm x 110mm x 110mm (WxHxD) The microphone also includes a bass roll-off switch with a knee point of 160 hz (1/8" output only). With the power switch in the ON position, the battery will last 300+ hours of continuous use (3.5mm output only). The FS Pro II binaural microphone can be powered by the pre-installed 9V battery or phantom power via the XLR outputs. Custom made, hard shell carrying case for easy transport and safe storage. The base of the microphone has a 1/4"-20 female thread mounting hole that can be connected to a hot-shoe adapter or used to mount directly onto a tripod or grip handle. The microphone stand adapter is removable. Comes standard with a 5/8" microphone stand adapter installed in the base. Free Space Pro II Binaural Microphone with silicone ears ![]() Please see pictures for an accurate representation of the condition of the microphone. This microphone may have little hairs stuck on its silicone areas from a towel used to clean the product. There are signs of light use-some of the metal, circular areas may be missing paint along their border. Providing an amazingly rich and silky smooth sound, it delivers flawless performance with pristine highs and a rumbling low-end.įully functioning, in excellent condition, barely used. With a wide dynamic range, the FS Pro II ideally is suited for professional recording studios, content creators, filmmakers, field recordists, and sound designers that are looking for an immersive binaural soundscape. The flat frequency response and dynamic range of the capsules results in a very open and dynamic binaural realism, especially during very delicate recordings. The FS Pro II features two matched DPA 4060 CORE hi-sensitivity capsules mounted inside each ear canal delivering a very sensitive and natural binaural sound. If you are looking for the best binaural microphone on the market, look no further than the 3Dio FS Pro II binaural microphone. ![]()
