Abstract:
Audio enhancement became important when noise in signals causes loss of actual information. Many filters have been developed and still improving. A highly optimized core discrete Remez part of the Parks-McClellan (PM) filter along with wavelet type discrete symlet filter been proposed in the paper. The proposed algorithm DWT-REA is experimented for two speech signals and efficiency is checked with calculation of MSE. Performance is also evaluated for different value of noise level. Proposed Algorithm is also compared with simple REA for seeing the improvement in recovered signal. Proposed algorithm can easily applicable in the field of speech enhancement.
