A system is disclosed for playing prerecorded audio encoded in a fault tolerant manner as a series of invisible dots carried on a substrate together with a photographic image. The system has a detector that detects the dot form of the prerecorded audio on the substrate and outputs a first signal; a decoder interconnected to the detector that decodes the first signal to produce a output signal; and an audio emitter interconnected to the processor that receives the output signal and outputs corresponding sounds. The dots may be infrared absorbing and the encoding can include Reed-Solomon encoding of the prerecorded audio. The system can include a wand-like arm having a slot through which the photograph is inserted.
An audio playback device for playing prerecorded audio represented by an array of ink dots printed using a pagewidth printhead at a resolution providing about six Megabytes of audio in infra-red ink on an image carried by a substrate, a substrate carrying an image and including an array being substantially identical, to an average unaided human eye, to the same substrate and image not including an array, the audio playback device comprising:
