Hi guys,am working with my project on the design of a software that will give the values of resisters to the given gain and transistor parametres.
May u help me with more advice so that i could come out with something which sounds.

 

You almost have to decide with amps you're going to support. I did something similar in the 80's for a common emitter design, w/ emitter swamping resistor and 2 base bias resistors. This is because the formulas vary for each configuration.

SPICE, as I understand it, already does something similar, in the sense it will test an existing design.
