Abstract

Apparatus and methods enhancing radio programming include receiving a broadcast radio transmission at a communication device. The broadcast radio transmission includes primary content and supplemental content having a relationship to the primary content. Further, the primary content includes a first audio data, while the supplemental content includes audio data. Additionally, the apparatus and methods include converting the supplemental content into converted supplemental content, maintaining the relationship to the primary content. Moreover, the converted supplemental content includes second audio data converted from the non-audio data. Thus, the described apparatus and methods allow the communication device to output signals for generating audible representations of both the primary content and the supplemental content.
