Voice-Based Internet Connection App MelodyLink is a voice-based internet connection application that listens to audio-encoded URLs through smartphones and other devices, then connects users directly to the corresponding websites. Until now, internet access has primarily relied on one-dimensional text or two-dimensional images such as QR codes. MelodyLink transforms this experience by using patented technology that enables internet connections through audio signals transmitted in three-dimensional space, effectively turning smartphones and other devices into a new type of interactive media. The MelodyLink app provides two core functions: 1. Receiver Function – Receives and recognizes audio signals containing encoded URL information. 2. Media Function – Decodes the URL embedded in the audio signal, connects to the designated website, and delivers the site’s content and information directly to the user through the device.
