Dynamic refers to the ability to position the sound stage at different positions as the engine operates at various RPMs and load. In order to control the sound stage width, a phase difference can be introduced between a first audio channel (e.g., a left audio channel) and second audio channel (e.g., a right audio channel). In the most general case, the phase difference can be introduced per harmonic per RPM. In this approach, the phase difference can be adjusted such that a vehicle occupant will perceive each harmonic signal to have a particular width. This width can be adjusted independently per RPM regions by tuning the per harmonic phase difference."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic engine harmonic enhancement sound stage","description":"A method to produce a dynamic sound stage for engine harmonic enhancement (EHE).
