DirectShow filter: Audio processing using Bezier Curves

** Dear RentACoders, We are looking for a talented DirectShow filter developer who can create a new filter from scratch. ** Our goal is to restore audio that's been clipped due to high volume. We created an exact algorithm that we want to use. It uses an implementation of [Bezier Curves][1] and volume adjustment to restore clipped audio. **_Step-by-step approach_ ** 1. Take input from audio stream 2. Detect clipped peaks (where audio signal exceeds maximum allowed volume for at least three consecutive samples) 3. Calculate angle/slope of the last X-number of samples that led to the clip 4. Calculate angle/slope of the next Y-number of samples after the clip 5. Create a four-point Bezier Curve to get missing sample values 6. Add the missing values to the output stream to restore clipped audio samples 6. Return the output _**Developer Requirements** _ 1. You have to be familiar with Audio Processing and DirectShow filters 2. You have to implement our algorithm using Bezier Curves and use them to shape sound 3. No third-party source code is allowed. Entire project has to be written from scratch. 4. We can provide graphics to visualize how the math should work _**Additional notes**_ This DirectShow filter has to accept all types of audio input, including 16bit ane 24bit streams. If you are a professional DirectShow developer with a firm grasp of mathematics, we look forward to having you onboard! This should be an interesting assignment with a high coolness factor. We look forward to your bid. Thank you. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
