Re : Minim .get() never gets two times the same result when you run again the analysis

so you just can average that.

I disagree

Did you try to put it all in an array or ArrayLIst and save that and analyze that?

I should always look the same. (not tested)

1. void draw()
2. {
3. 
   
4. for(int i = 0; i < song.bufferSize() - 1; i++)
5. {
6. arrLeft [counter] = song.left.get(i)  ;
7. arrRight [counter] = song.right.get(i)  ;
8. counter  ++;
9. }
10. 
    
11. }

[Edited]
because then the buffer size is not important anymore, so (analysis) time is not in the equation.
Since we add up all buffer states in one array.
