well i might be wronk, couse im new to this, but arduino reads the signal in 8 bits, and that quality sounds (if you want to make audio amp). not to mention that the signal will be less than 5 volts, because then there would be no point in amplifying it, which means that from the 8 bits you will be using about half (depending on input signal lvl)... that means 4 bit signal (also depending on input signal lvl)... am i right?
No, the ADC is 10 bits.Standard PWM out is 8 bits, but 16 bit PWM is supported by the hardware.He didn't say what kind of amplification - voltage or current.Aref can be adjusted - if incoming signal is 0-1V, then Aref at 1.1V will allow full 10-bit resoution. If Aref was at 5V, then a smaller range would result as you suggest.
