I need an audio processing expert (digital signal process expert) to develop a C/C++ (and/or iPhone) application. 1) Project Description: Please look at http://www.tvtak.com/. On the smartphone, when the user points at the TV, TvTak first detects the surface of the television display, and then computes an "identifier" of the video playing on the TV with its unique graphical characteristics. What I need is development of similar technique(application). But using audio part instead of image part of video. 2) Detailed information Suppose I have a TV show(video) which will be played in TV. - Encoding: First I embed a certain 16 bit information by using "Encoding App". Encoding App generates an audio pattern that is at a frequency the human ear can't hear but a smartphone or tablet microphone can hear. And then integrate the generated audio pattern into original audio pattern of the TV show. Like this I get "encoded video" - which will be actually played in TV. - Decoding: On the smartphone, when the I points at the TV which is playing the "encoded video", Decoding App recognizes audio part of the video and decodes the embedded information. Like this I get the 16bit data what I embedded. 3) Delivery - Encoding app by using c/c++. - iPhone app which works like default camera program, but has the decode feature mentioned above - Technical document that describes the embedding technology( or algorithm) 4) Others If the programmer can develop both of 2 apps, it's OK. If not, he can develop the decode app with c/c++ also. When you place a bid, please write about below things: - Your experience about development of same or similar project. - Your experience in audio processing. Serious bidders only and right person will have more jobs. Thanks.
