With this set of microphones, the slight difference in the waveforms created by the sound sources are captured by the left and right ears. One builds two microphones inside two fake ears and puts them on a model head. While it sounds complicated, the concept behind the recording technology is rather simple. This stimulates greatly a sense of distance and direction for listeners. By recording the sound on set and then transferring the sound files to the clients, Binaural Recording aims to recreate the exact same sound experience for human ears. This is a sound recording technology that came out over 100 years ago that was used to recreate the experience of watching a play or concert for people who could not actually be there in the theater. This actually refers to another technology called “Binaural Recording”. But if one googles “3D sound”, the similar terms will appear in the results. Many people call Atmos a “3D sound experience”. Dolby’s official website introduces the new features of the Atmos system and shows some examples of how it sounds. Films like The Life of Pi, The Hobbit: The Battle of The Five Armies, Gravity,The Martian and many others all used this new sound system. The biggest difference between this new system and traditional surround sound is the extra speakers on the ceiling, which help to create a better spacial sound atmosphere. Beginning in June 2012, Dolby introduced the more complex Atmos system, hoping to create a 3D aural experience in theaters. Surround sound uses sets of speakers to create a multidimensional sonic atmosphere. Filmmakers agree that the most effective way to do this is with three-dimensional sound. However, they are also working just as hard to improve film sound, aiming to make the moviegoing experience more real and impactful. Filmmakers continue to test the limits of how they can improve picture, coming up with innovations such as IMAX cameras, 3D capture and 4K resolution.
