Theme: Recording from the acostic to raw-wave-data, decoding a picture.
To making
recoding in the acostic in the room.
decoding the RGB pattern
and decoding the character pattern


Result: too bad: the acostic rings in 0 dB like a insect, thus I can record the raw-wave-data

good: QVGA scaning, prob.

good: the sentence is e-mail,

too bad: I had fixed the picture at the point of red. prob. I'm sorry.
