audio like music has only appeared recently. The Wavelet Transform (WT) and more particularly the Discrete Wavelet Transform (DWT) is a relatively recent and computationally efficient technique for extracting information about non-stationary signals like audio. This paper explores the use of the DWT in two applications. The first

To transform the signal back to the original audio signal, I then perform an inverse wavelet transform on the signal using the function wavrec. The output of this function brings me back to the original audio signal. However, many data points are slightly off from the original signal (only by about a magnitude of 10^-16 so it is very slight).
