Harmony Hub is a web-based application designed to alleviate tinnitus symptoms during music listening by applying split-ear notch filters at user-specified tinnitus frequencies. A key challenge was balancing audio quality with filtering to ensure a satisfying listening experience. We leveraged Creative Commons music to support underground artists and maintain compliance with commercial licensing standards. The outcome is a personalized platform that reduces the perceived intensity of tinnitus while promoting emerging musicians. Harmony Hub empowers users to manage their symptoms and increase emotional music connectivity, offering a unique intersection of auditory therapy, user-driven customization, and ethical music streaming.
