This is not an Answer to your question. Besides, you need to give the volunteers time to answer your question. 2 minutes is not enough time to expect an answer. When/if someone answers, you can reply to them with a "Comment" not an "Answer." Also, please list what toolboxes you have that might be needed for this, for example the Signal Processing Toolbox, in the "Products" panel above.
