Abstract:
The Wavelet Transform (WT) is a transformation that can be used to analyze and represent the temporal and spectral properties of non-stationary signals like audio. The combination of time and frequency localization is important for coding audio signals. The WT yields a compact representation of signals without an a priori knowledge of signal statistics. In this work the approach for discrete audio signal decomposition using wavelet transform are described. The developed by MATLAB 6.5 programming algorithm aims to minimize approximation error and decrease the mismatch of the original and the converted signal.
