Detailed Documentation
This example demonstrates source code implementation for four-level wavelet packet decomposition and reconstruction of signals. The data file to be decomposed is stored in the a.wav file located at E: directory. The implementation utilizes wavelet packet transforms to achieve finer frequency band partitioning compared to standard wavelet decomposition, employing functions like wpdec for decomposition and wprec for reconstruction to analyze signal characteristics across multiple resolution levels.
