Abstract

Radio programmes are now frequently downloaded by listeners or delivered automatically to media players using a technique called Podcasting. These media players frequently use ID3v2 metadata embedded in the audio files to catalogue and index the programmes, making navigation and selection of the content easier for users.

This white paper proposes a way to provide audible metadata within an audio file that is equivalent or an alternative to the existing textual metadata. This audible metadata would allow appropriately adapted media players to provide a greatly improved user interface for the visually impaired.
