Processing and analysis of acoustic wave data using DSP based real time wavelet transform

Some mechanical and other physical processes, while occurring, generate a number of short acoustic wave pulses. They can be detected depending on the location and type of source of these acoustic waves. Results of wavelet transformation show good contrast between acoustic wave data and noise, and some features of the processed signal are clearly visible. WT is less numerically demanding algorithm than FFT, but real time processing is on the brink of abilities of a single processor. Array of processors shuld be used for more demanding applications.
