What is Binaural Sound?
A world of three-dimensional sound convincingly heard through any pair of headphones

Binaural sound refers to an audio signal that represents three-dimensional sound, which is paired to the left and right ear, mimicking how we hear in real life. Binaural rendering refers to the processing technology that inputs an audio signal into a two channel signal, which is separately delivered to the left and right ear. Unlike binaural recording, which requires a binaural microphone to record sound in the beginning process, binaural rendering can take any type of input audio signal and process it as a two channel output signal.

How Binaural Rendering Works
Listen to sound as if it is coming from a certain position

An audio signal is actually a waveform containing a specific amount of pressure that dictates how it will sound in that exact moment. Binaural rendering additionally assigns positional information to the audio signal. This position can even be externalized, where sounds appear to be coming from hearing outside the head, compared to sounds coming from inside the head that is typically heard with headphones. More specifically, binaural rendering uses what’s called Head-Related Transfer Function (HRTF) that mirrors how a sound source in that position will sound for each ear. In other words, well-defined HRTF data is fed into the audio source to make it sound like the audio is coming from that specific place.

Unparalleled Binaural Rendering Technology
Immersive sound with minimal processing

G’Audio Lab’s innovative binaural rendering technology was integrated into the MPEG-H 3D Audio international standard by the ISO/IEC committee in 2014. This decision was based on its ability to deliver the best sound quality while requiring minimal processing power. This binaural rendering technology has enabled a software driven approach across all of G’Audio Lab’s production and rendering solutions, freeing users from expensive 3D headphones or additional hardware gadgets.

Natural Sound in Any Context
Transforming 3D sounds into a two-channel signal or more

Sound adjustments made relative to the listener's point of view is not bounded by headphones and can be enjoyed on multiple types of listening devices. Our audio processing and rendering technology can deliver spatial audio in various audio output scenarios, including soundbars and 5.1 speaker layout. Regardless of the type of output representation you are listening with, spatial audio will always be expertly fitted when using our rendering solution.
