How do I apply a wavelet decomposition filter?

Hello everyone, I applied stft to audio files. But I want to apply wavelet decomposition filter before stft. However, I couldn't. I would be very happy if you help.

windowLength = 256;
win = hamming(windowLength,"periodic");
overlap = round(0.75 * windowLength);
ffTLength = windowLength;
fs = 16e3;
numFeatures = ffTLength/2 + 1;
numSegments = 8;
inputFs = 16e3;

%% STFT 
cleanSTFT = stft(audio,'Window',win,'OverlapLength',overlap,'FFTLength',ffTLength);
cleanSTFT = abs(cleanSTFT(numFeatures-1:end,:));
