Glyphs could maybe encode data from a digital sample on paper and be "played" via optical scanner (or really high-res camera). |
|
| |
Are you proposing to print something like the waveform that is viewable in sound editing software? Could you get enough of that on a business card to reasonably reproduce such sounds as proposed? |
|
| |
...or just include a URL where a sound
sample can be found. |
|
| |
That seems a lot like the failed CueCat. |
|

The advantage of [Ling]'s idea is that future societies could hear, for instance, what birds sounded like. If out technology is ever lost then everything compressed will be difficult or impossible to decode. |
|

I can imagine a buisness card has enough data storage area for a few seconds of sound. |
|
| |
If a business card is 10cm x 6cm (??),
and if each pixel is 1mmx1mm
(conservatively, to allow for poor
printing, dirt, creases...), then a card
could hold 60kbits of printed data.
Should indeed be enough for a few
seconds of sound, especially with
compression. |

[half], thanks for your link. I was proposing that the waveform be printed as you mention, but a quick calculation at 600dpi and maximum frequency 4kHz, means 1 second of sound recorded over 26 inches of waveform. Erm...
The dataglyph system can record 1kB data in 1 square inch. However, to play either system back would require something like a hand held scanner, with today's technology.
I have linked to PARC solutions, who give more details. It is interesting to note that the coding can be 'invisibly' contained in a printed photograph.
Maybe a small scanner could be swept over the objects in question, on a page, and each object could contain sound information. |

Build the technology into a cell phone with a camera. |
|
| |
2D barcodes can hold about 2K (1800 bytes). |
|

Using the CELP 4.8 Kbps algorithim and the PaperDisk program I have been able to store a 3 -1/2 minute song using both sides of an 8-1/2 by 11 inch sheet of paper using an inkjet printer and a scanner. It would be cool if they made an open-reel tape player that played sound digitally and optically on paper that you could print on your home printer. |
