audio - Wavelet Transform Output in MATLAB - Stack …
https://stackoverflow.com/questions/19732284/wavelet-transform-output-in-matlab
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).
Wavelet Transforms in MATLAB - MATLAB & Simulink
https://www.mathworks.com/discovery/wavelet-transforms.html
Wavelet Toolbox™ for use with MATLAB ® supports Morlet, Morse, Daubechies, and other wavelets used in wavelet analysis. Audio signals, time-series financial data, and biomedical signals typically exhibit piecewise smooth behavior punctuated by transients.

Audio Compression using Wavelets in MATLAB Audio frequencies range from 20Hz to 20kHz but these frequencies are not heard in the same way. Frequencies below 20Hz and above 20kHz are very difficult to hear, while those not much more than 20Hz, or not much less than 20kHz, cannot be heard by most people.

Audio/video compression frees up space substantially, which can then be utilised for other purposes. This article describes some important audio compression techniques. An audio signal sample is taken and analysed using MATLAB for frequency and amplitude. Haar and Daubenches algorithms are applied on the speech signal and the audio is compressed.
