I am developing one simple audio processing application in C++ using Qt.It can record audio from microphone. When I play the recorded sound there is lots background noise in it. Is there any simple code I can remove the background noise from audio sample
I tried to replace zero to the below audio sound but the recording coming through choppy and I searched in net for noise reduction methods found some algorithms that all are very difficult to understand and implement in my code

Any code sample will very helpful to me

Unfortunately, all good noise reduction algorithms are in one way or the other complicated. The two simplest approaches I know of are a low-pass filter and a median filter. More advanced approaches use more complex digital filters and make the filtering process itself dependent on the spectral distribution and amplitude of the signal.
