Audio Analysis using the Discrete W avelet Transform
https://soundlab.cs.princeton.edu/publications/2001_amta_aadwt.pdf
Abstract: - The Discrete Wavelet Transform (DWT) is a transformation that can be used to analyze the temporal and spectral properties of non-stationary signals like audio. In this paper we describe some applications of the DWT to the problem of extracting information from non-speech audio. More specifically

Wavelet analysis for audio signals with music classification applications Abstract: Audio data like speech and music can be analyzed and processed with Fourier methods, having as one constraint the constant product of time and frequency resolutions.
Wavelets in real time digital audio processing: Analysis ...
http://www.boemers.de/personal/thesis.pdf
This thesis will evaluate the wavelet theory for the use in real time digital audio processing. Wavelets provide a new way of gathering frequency information from musical signals. Contrary to the traditionally employed technique for doing that based on Fourier transforms - the STFT - time information is not lost in a portion of analyzed audio data.
Signal Aligning Using Wavelets - Prosoundtraining

When attempting to “align” things in audio and acoustics, wavelets can prove to be very useful. They allow us to distinguish between delay, phase shift, and polarity using an intuitive method that is easier to interpret than an impulse response or a transfer function.

A Practical Guide to Wavelet Analysis
https://paos.colorado.edu/research/wavelets/bams_79_01_0061.pdf
Wavelet analysis is becoming a common tool for analyzing localized variations of power within a time series. By decomposing a time series into time–fre- quency space, one is able to determine both the domi- nant modes of variability and how those modes vary in time.

In particular, the Wavelet Transform (Wf) is of inter est for the analysis of non-stationary signals, because it provides an altemative to the classical Short-Time Fourier Transform (STFT) or Gabor transform [GAB46, ALL77, POR80]. The basic difference is as follows. In contrast to the STFT, which uses a single analysis

The wavelet transform or wavelet analysis is probably the most recent solution to overcome the shortcomings of the Fourier transform. In wavelet analysis the use of a fully scalable modulated window solves the signal-cutting problem. The window is shifted along the signal and for every position the spectrum is calculated. Then this process

The wavelet analysis procedure is to adopt a wavelet prototype function, called an analyzing wavelet or mother wavelet. Temporal analysis is performed with a contracted, high-frequency version of the prototype wavelet, while frequency analysis is performed with a dilated, low-frequency version of the same wavelet.
