Abstract—In this paper, an adaptive filter has been designed and simulated for enhancing an audio signal. The designed filter is based on Block LMS algorithm wherein a comparison has been made for enhancement of audio signal buried in both periodic sinusoidal and FM modulated noise. The enhancement has been perfomed using leaky and non leaky algorithms by varying the convergance rate. The performance has been evaluated using Signal to Noise Ratio (SNR) for each.
