Abstract
A method and apparatus for printing a one-dimensional, continuous signal, such as a sound wave, as a printed pattern and for recovering the sound wave from the printed pattern. The method decomposes the one dimensional signal two-dimensional function that is continuous in both dimensions. The two-dimensional function can be printed as a pattern on to a paper substrate using a standard printer. The audio signal is recovered by scanning the pattern and processing the scanned values.
