A system is disclosed for playing prerecorded audio encoded in a fault tolerant manner as a series of infra-red ink dots printed along with a photographic image using an ink jet printing system, the system comprising an infra-red scanner for scanning the infra-red (IR) form of the prerecorded audio; a processor interconnected to the IR scanner for decoding the scanned audio encoding to produce a corresponding audio signal; and an audio emitter interconnected to the processor for emitting or playing the corresponding audio signal on demand. The encoding can include Reed-Solomon encoding of the prerecorded audio and can comprise an array of infra-red ink dots which are high frequency modulated to aid scanning. The system can include a wand-like arm having a slot through which the photograph is inserted.
A device for playing a prerecorded audio signal printed as an array of infra-red ink dots in a fault tolerant encoded form on a surface of a photograph coincident with an image printed on said surface of said photograph, said image and said infra-red ink dots having been printed by a camera having an in-built printer, the device comprising:
