Sound based condition montoring

    1. The problem statement, all variables and given/known data

    Hi Guys,
    Basically i'm got some engine sound data in MATLAB form that needs analysis and diagnostics.I was able to source out a couple of methods of plotting the data.This was done via FFT,power spectrogram and a probability density plot.
    But here's the problem,i dont know any techniques for extracting features from these analysis results.Because i need to use these features rather than the analysis results (shown in my diagrams) for fault detection and diagnosis.

    I'd deeply appreciate it if anyone can push me in the right direction.

    2. Relevant equations



    3. The attempt at a solution
