I have a data server program running a TCP/IP or UDP/IP data server which is streaming the data to a port with...the data to a port with a given data rate. The FFT spectrum display program should connect to the server, get the data stream, collect N data points in a buffer and run an FFT spectrum estimation in every T time and display the spectrum on the screen as a frequency vs amplitude (in dB FS full scale) display plus a waterfall diagram. For FFT: or The data stream contains complex base band samples (IQ) represented as 16bit I and 16bit Q samples, for frequency scale the original sampling frequency should be entered into the display. Some electrical engineering and/or signal processing background is very useful for this project.
We need a musical tuner library for iPhone OS that can: * Play a certain tuning note on a certain pitch * Recognize the note played by a musician and compare it to the configured pitch. It must be able to display the difference in a graphical way. The settings that must be possible: * Setting the note to hear. * S...--public String getStandardNote() - standard note (A) The implementation must be able to tune in multiple octaves. It is recommended to use the sample JAVA code to make a Objective C equivalent. This example doesn't include the FFT (DoubleFFT_1D class in the JAVA example). You are advised and allowed to use: Other libraries need to be approved before you may use them.

We need a C# wrapper for Kiss FFT (Keep it simple stupid Fast Fourier Transform) so we can access all of the Kiss FFT functions from .NET. Kiss FFT is a BSD-licensed project at We are using the Kiss FFT code for a microcontroller implementation and want to be able to use the same code from a GUI we have in C#. We started to do the port but realized that this would be a good initial project for us on GAF. For an example of what we mean by a C# Wrapper, please see what was done for the FreeImage project. () We have not written such a wrapper before but it does not look hard (1-1.5 days work max if we did it ourselves). Deliverables should be as follows: 1) A VS2005 C project to compile
