Audio technology is an ever-changing industry. As with all technology, there are constant upgrades and changes that make it an exciting industry to stay vested in. one of the more recent changes has been the advancement and redefining of an old technology known as Binaural sound. It is an exciting technology that has many future applications.
Depending on the quality of the 3D mic that is chosen, there are many levels of sound that can be picked up at varying degrees of quality. By definition, Binaural microphones, also known as 3-D microphones pick up a higher grade of varying sounds in both microphones. Sounds of nature, human voice and music will come in sounding just as it does to the human listener live and will be recorded exactly that way. It will also allow for output with Binaural speakers to come out through the speakers the same way it is recorded.
What is Binaural Sound?
Binaural sound is different than normal audio recordings. Binaural sound is actually the same way the human ear hears everything. The human ear can hear all the high and low pitches of sound as well as all of the strength or softness of sound as it is played, spoken or created. By contrast, regular stereo sound is different. Stereo sound takes all sound and makes it equalized at the same level of volume. While this has certain advantages, it also has disadvantages. Stereo and surround sound is always at the same sound level that is preset by the person in charge of the sound system.
Binaural sound is the exact same sound that humans and all animals audibly hear from their ears. The ability to record this type of sound was actually developed in the late 1800’s but it implementation into modern technology did not occur on a more widespread level until the IMAX experience was finally developed.
While surround sound gives a person sound in a total encompassing way, IMAX Binaural sound implementation gives a person the feeling that they are living the experience live and in person. Part of this is because the sound comes out the way people are accustomed to hearing in person. This technology is also now being used in video game production as well.
However, in order to record this type of sound in a way that accurately reflects the sound output, the audio creator has to use what is called a 3-D microphone. These types of microphones are not sold at all audio places. Audio enthusiasts have to go to a place like Hooke Audio or a 3-D sound specialty audio sales outlet in order to get this type of technology.
What’s Different With 3-D Microphones?
A 3-D microphone takes in sound just the same way human ears do. They have two ports of sound entry and are most often designed with two human looking ears placed at a similar distance apart as human ears are on a human head. This allows for the sound to enter into each microphone and be recorded in the same way as human ears hear.
