This paper reviews the effect of sampling frequency on a FFT-based spectral estimator. In signal processing applications usually a fix window size is used for obtaining the current frame spectral. For an application like speech enhancement this accuracy of this estimation has a great influence in the quality of the system, because listener feeling is very important in this subject. In our proposed method we divided the well-known spectral subtraction method in two phases. Then by using different frame sizes that we used in these two phases the overall quality of the system has increased in different sampling frequencies.
