Virtual Reality is use in tech industry, entertainment, sport, mental health, education, and fashion.

Users have already discovered how the next generation is shaped by virtual and augmented reality (VR/AR) applications. However, think of another essential element VR/AR environment has – sound!


Significance of Sound

Without sound, the virtual environment is unrealistic. Users will experience full engagement in the virtual environment with the right sound in VR.

To ensure full immersion in VR systems, the spatial (three-dimensional virtual space) sound needed to match the spatial characteristics of the visuals. So, if the user sees a car moving away in the VR environment, the user will also hear the car moving away from him.

Spatial sound provides an enhanced surround sound environment compared to conventional surround sound format. With it, all movies, games, and songs will sound better.


VR audio hears like in someone else's head

Multiple loudspeakers used and positioned around the listener’s head to reconstruct an immersive sound field. This achieved by extending methods used in stereo recording and playback.

VR creators use sound not just users experience in a different atmosphere, but to put them in a different mental and emotional setting.


Using VR Sound Engineering Technology

Surround sound is history. Composing, developing, and producing VR sound requires expert views in two areas:

1. Sound-based engineering

  • It is challenging to show changes in user’s interaction, or time and space by producing sound effects, script sound, and background music. But it has the advantage of producing the sound effects, script sound, and background music in one track and not going through the coding stage.

2. Computer-based interactive sound engineering

  • Produced in different files, including the sound effects, script sound, and background music. It can increase engagement by showing user’s interaction, or time and space.

VR applications prefer VR produced with sound engineering to prevent noise cancellation. The spatial sound is used by companies such as Facebook and YouTube, which encodes sound files in a binaural method (two-channel surround format). Through this, users can hear sounds suitable for their environment over headphones.

Imagine how audiobooks can certainly provide a better experience for readers using these applications. We would love to hear more about your thoughts on spatial sound – leave comment below.
