You are better off squaring the signal. Applying an FFT to get the magnitude will smear your signal in time. I suggest you look into acoustic emission detection

- anfractuosity 9y agoThanks! I'd not heard of acoustic emission detection, I'll look into that now. Do you think my sample rate is high enough for acoustic emission detection, as I notice in your other comment you mention they often use sample rates many times higher. Also is there a particular paper you'd recommend regarding acoustic emission detection?
