Please, could someone assist me with code for wavelet analysis?

Hi all,

Please, I have an acoustic signals from a couple of experiments and would to explore the time-frequency characteristics. Having known of STFT or spectrogram analyis which usually provide better resolution in the expense of either time or frequency, I would like to compute the time-frequency using the wavelet transform.

With this I will be able to identify the time at which an event occurs without compromising on either time or frequency resolution,

Please, could someone assist or share with me MATLAB code to carry that exercise.

Thank you very much in advance.

Warm regards,

Kwaku.

Hi Kwaku Owusu,

It is my understanding that you want to use wavelet transform. You might find this documentation "Wavelet Transforms in MATLAB" useful.

cwt in Matlab is used to find continuos wavelet transform of a signal.
