The audio processing system may include a crossover network that separates an input audio signal into a low frequency signal and a high frequency signal. Subband spatial processing and b-chain processing are applied to the high frequency signal to spatially enhance the input signal, and adjust the input signal for the unmatched speakers. The low frequency signal is processed using a parametric band-pass filter and a first gain to generate a low frequency resonator signal, and a second gain to generate a low frequency passthrough signal. The processed low frequency signals are provided to the micro-loudspeaker by combination with one of a left channel or a right channel of the processed high frequency signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enhanced virtual stereo reproduction for unmatched transaural loudspeaker systems","description":"Embodiments relate to an audio processing system that adjusts for unmatched speakers, such as by frequency response, output power, directionality, etc. For example, a mobile device may include an earp","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10499153","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
