The system may include a sound device, a smart phone, and a processor. The sound device may modulate a code where a first set of frequencies represents a logic 0 and a second set of frequencies represents a logic 1. The smart phone may demodulate the modulated code to reproduce the code. The smart phone may send the code as a query to a processor. The processor may receive the query, determine content associated with the code, and send the content over the network to the smart phone. The smart phone may further receive the content and display the content on a display."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System effective to modulate a code and provide content to a user","description":"A system and method effective to provide content to a user.
