Good day, my goal is to use the envelope() function to take sound signals and plot it's outskurts, so only it's amplitudes. Given an array of all the amplitudes of this sound signal, i was told I could use the envelope() function to create a new array plotting the outskirts of the signal making it easier to find words spoken in the sound wave. I'm unsure how to do this and am struggling to understand how the function works. If possible could I please get examples on how the function works (explain it as if I'm a dummy, cause at this point I think I am). Thanks a lot in advance!
