[SoX-users] SoX plot coefficients

[Marco B. <mar...@gm...>]

I need to plot the amplitude frequency response of SoX bass, treble and 
equalizer commands by using a spreadsheet.
I have opened .plt files resulting from SoX --plot gnuplot command and I 
 have found H(f) formula.
Where could I find the formulas for coefficients a1, a2, b0, b1, b2?
Please, could you send them to me?
 
 Thank you very much.
