    The tech essentially takes a 5.1, 7.1 or Dolby Atmos signal, and applies a series of audio filters and EQs to those different channels, making it sound like those audio tracks are placed around you.

    back. The consequent non-linear spatial filter uses the differ-ence between the signals in the two beams to build spatial statistical models and to compute the probability the signal come from the desired direction for each frequency bin. Then it is applied suppression gain, reducing the signal from am-bient noise and unwanted sound sources.

    The process of playing spatial audio through two earbud or headphone speakers is called binaural rendering, with binaural meaning "through two ears." OnQ: What is personalized spatial audio? AL: Human anatomy is unique to each individual, so some spatial audio technologies use personalized HRTF filters. These HRTFs are generated from an analysis of a …

    • Beamforming is spatial filtering, a means of transmitting or receiving sound preferentially in some directions over others. • Beamforming is exactly analogous to frequency domain analysis of time signals. • In time/frequency filtering, the frequency content of a time signal is revealed by its Fourier transform.
