NFC Talk is a peer-to-peer chat application demonstrates the use of Near Field Communication (NFC) technology on Windows Phone 8. This application has three pages: settings page, connect page and a chatting page. To run the application user needs to enter a name in the settings page. Connect page is used to establish a connection between two devices and chatting page to send message between them. To know more about NFC Talk application architecture and the API usage, see Opening sockets with NFC article.

NFC brings a fast and easy way of data transmission between devices. Windows Phone 8 platform uses Proximity API which opens a communication channel between two devices, just by tapping the devices together.  To learn more see Windows Phone 8 Proximity API reference .

Digital Signal Processing(DSP) by Sebastiano Galazzo (galazzo to the Nokia Developer Community) is a project which delivers a collection of useful tools that implements DSP algorithms. With the use of 1D Fast Fourier Transform algorithm author has demonstrated Audio Noise Reduction and Sound pattern matching in Windows Phone.

The next action plan of the project is to bring digital image processing like image matching, compression, etc. using 2D Fast Fourier Transform. Till now we are not confirm whether will it be a geometric image matching or a regular image matching or/and will there be a loss-less image compression or not. But this project sounds much promising to bring new and exciting features.
