Steganography doesn't work as pictured here. More likely you could have two audio or image files, between which every sample or pixel only differ a little, so the "carrier" file (into which the hidden data is encrypted) would sound or look OK. The person who has the "key" file, would then compare the key file with the encrypted file, byte by byte, to extract the encrypted data. However, this method can't hide a file with resolution equal to the carrier file resolution (one or perhaps two bits per byte only). So the image of the girl couldn't have been encrypted into the picture of the house without visibly distorting the data. See more
