Recursive averaging

WebIn this letter, we introduce a minima controlled recursive averaging (MCRA) approach for noise estimation. The noise estimate is given by averaging past spectral power values and using a smoothing parameter that is adjusted by the signal presence probability in subbands. The presence of speech in subbands is determined by the ratio between the … WebOct 7, 2024 · 1 I need a function called average (a), where a is a list, and it returns the average of the elements using recursion. I solved it with an auxiliary function called sum (which solves recursively the sum of all elements of a list), but I want to solve it within the average function. This is what I have tried:

WebBe aware that the moving average recursive filter is very different from typical recursive filters. In particular, most recursive filters have an infinitely long impulse response (IIR), composed of sinusoids and exponentials. The impulse response of the moving average is a rectangular pulse (finite impulse response, or FIR).
