3 chiều audio or spatial audio is emerging as the next evolutionary stage in sound, but like many other new, unfamiliar media technologies, the terminology & descriptions may seem confusing and hard to lớn grasp at first. We had a chance khổng lồ sit down with Waves Audio’s Senior Director of Business Development & Marketing Adam Levenson và ask eight important questions. Hopefully what we learned will give our readers a deeper appreciation for the immersive sầu qualities of spatial audio.

OnQ Team: For starters Adam, what exactly is spatial audio?

Adam Levenson: Spatial audio describes a variety of sound playbachồng technologies that make it possible lớn perceive sầu sound all around you without the need for any specific multiple speaker setup.

OnQ: Can you go over the difference between stereo, surround sound, & spatial audio? AL: Both stereo and surround sound formats such as 5.1 và 7.1 are tied khổng lồ fixed speaker setups. Throughout the years, masterful works have sầu been produced using stereo and surround including some of the most beloved music & movies. But if real-world sound is the ideal, then these formats only provide windows inlớn that ikhuyến mãi experience. Spatial audio allows listeners khổng lồ step out of a windowed vantage point và into lớn an immersive sầu, emulation of real-world sound.

OnQ: Are there different kinds of spatial audio? AL: There are several different spatial audio products available lớn consumers. There are "object-based" formats in which the location of a sound is baked inkhổng lồ the position of the thing that emits the sound such as a oto passing by in a movie, or violin playing stage left. Then there"s "Ambisonics" that provides a sphere of sound centered around the listener. There are spatial virtualizers, technologies that project sound into a virtual acoustic space. Waves Nx is a virtualizer capable of spatializing any stereo or surround content.

OnQ: How is it possible lớn hear spatial audio on earbuds or headphones?

AL: Human hearing has evolved over millennia to allow us khổng lồ precisely and rapidly identify the location of sounds. Our brains interpret location cues according to lớn how sound interacts with our hearing anatomy including the shape of our ears and heads. Over earbuds or headphones, spatial audio technologies emulate that acoustic interaction khổng lồ stimulate the mind into lớn perceiving sound in 3 chiều. That emulation is achieved through sound filters called Human Related Transfer Function or HRTF. The process of playing spatial audio through two earbud or tai nghe speakers is called binaural rendering, with binaural meaning "through two ears."

OnQ: What is personalized spatial audio? AL: Human anatomy is unique lớn each individual, so some spatial audio technologies use personalized HRTF filters. These HRTFs are generated from an analysis of a photograph of your ear(s), or from measurements of your head và the distance between your ears.

OnQ: What is head-tracking & why is it an important part of the spatial audio experience? AL: On conventional earbuds or headphones, turning your head means the sound turns with you. The sound is between your ears, so where your head goes, the sound goes, even if you are listening lớn spatial audio. But with headtracking, a turn of the head accurately changes your listening angle: as you look around, the sound field remains anchored in place, just lượt thích it does in the real world. Center stays in the center, left stays left, right stays right, rear stays in the rear. In addition khổng lồ HRTFs, headtracking is another experience vector that produces a convincing, believable 3D experience.

OnQ: Is it possible to experience spatial audio over speakers? AL: The acoustic principles that make perceiving spatial audio possible over a pair of earbuds also apply to technologies that produce spatial audio from two or more speakers. Earbuds and headphones have a built-in advantage in that each speaker is acoustically isolated by the proximity to your ear and by the obstacle of your head. Over speakers, this acoustic isolation is achieved through a process called cross-talk cancellation.

OnQ: Does spatial audio only work with special content? AL: Some popular spatial audio formats require the content khổng lồ be produced using proprietary authoring tools & require the user khổng lồ have sầu playbaông chồng hardware, such as a trang chủ theater receiver, equipped with special decoding technologies. Other solutions use virtualization techniques that are capable of spatializing any nội dung in stereo, surround, or spatial formats.
