Abstract


Audio signals are frequently infected by background environment noise and buzzing or whining noise from audio equipments. Audio denoising is the technique intends to satisfy the noise as retaining the fundamental signals. For the elimination of noises from the digital audio signals more number of denoising techniques is introduced by the researchers. However the effectiveness of those techniques remains a problem. In this paper, an audio denoising technique based on contourlet transformation is proposed. The contoulet transform which is more efficient in finding and removing the noises. Denoising is carried out in the transformation domain and the enhancement in denoising is attained by a process of grouping closer blocks and creation of multidimensional arrays. In this technique each and every finest detail supplied by the grouped set of blocks and also it protects the important unique features every separate block. Every block are filtered and restored in their original positions from where they are separated. The grouped blocks overlap each other and therefore for every element a much different assessment is obtained that are to be combined to remove noise from the input signal. The experimental result shows that the proposed Contourlet and the Daubechies’s transformation is more efecient when compared with the other techniques.
