The amplifier section is built around TL072 (IC3) and a low-power amplifier LM386. The op-amp A1 of IC3 operates as a low-noise preamplifier. Capacitor C8 is used in order to pass low frequency. The op-amp A2 of IC3 operates as a low-pass filter. For changing the cut-off frequency, you have to change the values of capacitors C11 and C12.

Firstly, connect the Low Power Audio Amplifier circuit according to the circuit diagram given in this article. As you can see, IC LM386 is the major component in this circuit. This IC is actually the audio amplifier that allows inverting and non-inverting inputs. Inverting input is normally grounded and hence we also grounded that pin, which is pin 2.
