Abstract: Embodiments of the present invention use one or more audible tones to communicate metadata during a transfer of an audio file. Embodiments of the present invention communicate an audio file from a speaker in a recording device (e.g., a recordable book, toy, computing device) to a microphone in a receiving device. The audio file is transferred by audibly broadcasting the audio file content. The audio file may be a recording made by the user (e.g., the user singing a song, a child responding to a storybook prompt intended to elicit a response). The file transfer process uses one or more audible tones, such as dual-tone multi-frequency signaling (“DTMF”) tones to communicate metadata associated with the audio file. Audible tones may also be used to communicate commands that delineate the beginning and/or end of a file broadcast.
