ADITI SARAWAGI 8D AUDIO Music is ever evolving as is technology and when both of these come together, they literally create (sound) waves! 8D Audio has taken the internet and music world by storm and there is no escaping it. Technically you only have two real sound sources- the left and right earphone, but 8D audio makes it seem like the origin of the sound is above or beside you. It resembles the feeling of being present at a live concert with you swaying to the music all around you! 8D audio is basically an effect applied to a soundtrack where it is edited to make it seem like the audio is moving in a circle around your head and this experience is mainly effective with earphones. It gives an impression that the audio is coming from different directions and different distances. Sometimes, different echo types are combined with this and the experience becomes completely immersive. Some credit to the increasing popularity of 8D Audio can be given to VR games, 3D installations and 360° videos which have become dependent on full-immersion 360° audio. This is where 8D audio comes in. The most popular audio standard for such tunes is Ambisonics and a number of professional level tools are available to audio engineers these days. Ambisonics is a method for recording, mixing and playing three dimensional 360° audio. The format used is a 4-channel format called Ambisonics B-format, which uses only four channels to reproduce a complete sphere of sound. It spreads the sound evenly throughout the 360° sphere. Along with the horizontal plane, it covers sound sources above and below the listener as well. There aren’t any actual 8D recordings but it is basically 8D mixing of pre-existing recordings or songs. 8D music creators use various software’s to manipulate a song’s different stereo parts, moving and positioning them within a virtual 360-degree space. Many pop, hip-hop and rock songs have been remixed in this format like Thunder by Imagine Dragons and Castle on the Hill by Ed Sheeran along with a virtual barber shop 8D audio piece which have become sensationally viral. This technology has existed since the 1970’s but never really took off until now where young millennials have created 8D audio sounds with the help of various software’s. This viral trend has made a success story of a number of young millennials. The most popular 8D channel is ‘8D Tunes’ which has more than six million subscribers and around 200 million total views. Another popular channel is Trillion with around two million subscribers. There have been numerous reactions to 8D audio. Though some people find it distracting, some people say it is similar to a feeling of an ethereal high. Some reports have also come in where people have claimed it has helped them fall asleep and calm down their anxiety as well. Others claim that 8D audio is an out-of-body experience for them, actually helping them forget their physical pain. It has become almost therapeutic for some people-be it relaxation, or sleep. There is no scientific evidence to prove the connection between these binaural beats and physical relaxation, but the responses by listeners make it hard to deny the positive effect of 8D audio. With software’s becoming increasingly easily available and the frequent launch of new social media mediums, 8D Audio is the latest viral trend which looks like it is here to stay. The technology is getting more and more sophisticated with every passing day and listeners sure look like they are in for a treat. The Score Magazine highonscore.com 25
