Easy Mathcad Project

Hello all freelancers. We are looking for somone to write a dll (c++) that will connect as a user dll in mathcad To qualify for this project you must be able to create or wrap c++ dll's We will send you the info needed to make it mathcad compatible. This should be a very fast and easy project for a experienced programmer. Notes on project: We will not pay anything in advance. Once the dll is done and we test it to be sure it functions, we will send full payment We will require both the dll and the sourcecode. We are in a hurry, but this should be a couple hour project if you know what you are doing We need this in a 24-48 hr turnaround The Dll needs to have only 3 functions, you can create it from scratch or wrap a dll such as directsound or windows sdk. The functions are 1. Play sound (from matrix or array) 2. Record sound (matrix/array) 3. Play/Record asynchronous (same time) We will send a mathcad worksheet to the winner for testing his/her work. This dll will play a wav file from a buffer/soundcard-it will not use a physical wav file-all work is done from the buffer In effect we need to play and record wav sounds created by mathcad from inside mathcad Lastly, anyone pricing over budget will be ignored. There is a bonus for same day/overnight completion
