The MPEG sound coding standard utilizes the progressively windowed adjusted discrete cosine change (MDCT) to accomplish an excellent execution. Coordinate calculation of the MDCT in MPEG coding and of the converse MDCT (IMDCT) in MPEG deciphering are computationally concentrated errands. Accordingly, proficient calculations for the MDCT and IMDCT are of prime significance inside the sound coding and interpreting process. The forward and converse altered discrete cosine change (MDCT) are two of the most computational escalated operations in the MPEG sound coding standard. In this venture, we utilized Clenshaw’s repeat equation to change parts of the MDCT and IMDCT of the general length. Clenshaw’s repeat recipe is an effective approach to assess the entirety of results of ordered coefficients that obey recursive relations. Proficient usage of MDCT and IMDCT are gotten. The proposed consistent structures are especially reasonable for parallel VLSI realization. Simulation results are carried out using MATLAB for signal reconstruction by considering different signals. Further, the proposed approach is applied for signal compression and the compression results are obtained. It is observed from the simulation results that the proposed approach is more efficient that straightforward method.
