Our teacher gave us an assignment: Write a program to transform an audio track to time - frequency domain, and create a vector include at least 4 features extracted from transformed output signal.
I think that i have to write a program that read an audio file, transform it into an vector of signals, which is the input of dwt algorithm, and i will get transformed output signal. After that, i use the output as an input of some functions to get extracted features.
I have some serious problems, due to lack of knowledge. I have very limited knowledge of physic, math, audio processing. Assume that what i'm thinking are right, then i don't know how many signal arrays should i get from the audio track and how to do it. I haven't figured how DWT work and the meaning of the DWT output, so that i don't know what to do with arrays of input signal. And the last are the extracted features, what features can be extracted using DWT (maybe i just needed the keyword, if i could understand DWT).
Thank you for your help!
