The implementation will use the methods for FFT and IFFT provided by the Accelerate Framework, and be as optimised as possible for performance in iOS devices. The implementation will be a single Objective-C class with a single method. This method will take as input a pointer to a float buffer and the length of the buffer. It will return a buffer (that will be released by the caller) containing HALF the autocorrelation (excluding the symmetric part). For reference, the method signature and result should be equivalent to the one given by the following code: -(float *) autoCorrelationForValues:(float *) values length:(NSUInteger) length { float *ret=(float *)malloc((length+1)*sizeof(float)); float move[length]; memset(move,0,length*sizeof(float)); float res[length]; NSUInteger where=0; for(NSUInteger i=0;i

Dear Sir! I've just read your job post and much interested in your project. I have been creating high quality and excellent iOS and Android apps for 6+ years using Swift, Objectiv-C, Java. Here are some links to web& mobile apps which are developed by me. I'm expert in Geo-location, GPS tracking, Payment gateway integration, and Social media integration such as Facebook, Twitter and so on. I have good experiences in Firebase, Twillio Api, QuickBlox, AWS and so on.
