Sound Field Processing
Advanced algorithms perform sound field processing to emulate multi-channel audio from a two-channel source. This technology manipulates the sound waves to create an expansive audio space. By adjusting the timing, intensity, and phase of each sound wave, soundbars can present audio that feels surround-like.
Phase Shift and Time Delay
Each speaker in a traditional surround sound system is positioned to achieve a specific phase and delay in audio playback. Soundbars use similar principles by exploiting phase shift and time delay techniques. By manipulating when and how the sound waves reach your ears, soundbars can create the illusion of sound traveling from different directions, further enhancing the surround sound experience.
