The first obtaining unit obtains high-frequency audio signals from original audio signals. The regulation unit obtains a volume of the original signals and amplifies the high-frequency signals according to an amplification factor having a positive correlation with the volume of the original audio signals, to output improved audio components. The second obtaining unit obtains reference audio signals from the original audio signals. The synthesis unit synthesizes the improved audio components and the reference audio signals to output improved audio signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio signal processing circuit","description":"An audio signal processing circuit includes a first obtaining unit, a regulation unit, a second obtaining unit, and a synthesis unit.
