1. A method of obtaining an audio file, the method including:

  • providing at least one substrate on which at least one audio file is associated with, and uniquely identified by, printed visible data and a plurality of coded tags, each tag encoding an identity of the substrate and a location of that tag on the substrate, the audio file being recorded using a selection device and associated with the visible data and coded tags by interacting the selection device with the coded tags;

    associating the substrate with a digital version of the substrate in a computer system;

    determining from the digital version, using the substrate identity and tag locations, the identity associated with the coded tag of at least one audio file selected using the selection device wirelessly networked with the computer system, the selection device sensing the coded tags on the substrate to select the audio files; and

    downloading audio data to the selection device, from the computer system, using the determined identity.
