Ok. So either there is something I don't grasp about audio signals in general, or there is something up there. Problem: Every time audio sound is played, the spectrum displayed (in demo) ends differently. Try1: drum snare

Try2: same drumsnare

Shouldn't they be identical? Is this concidered in the terms of error "same" spectrum? Or am I missing something? I am working on an idea, where I need a thorough sound analysis, which includes FFT, therefore would need as precise data as I can get. Any insights?

    Are these the spectrum of the *exact same file*, or are they spectrum of two recordings of the same drum? The variation between very similar sounds from an instrument can be huge. – Linuxios Oct 27 '16 at 17:57
  • Exact same file. P.S. I moved on to other tools. – Danielius Dec 05 '16 at 19:49
