I am using the following circuit to make a computer microphone. The "speaker" component is the computer's microphone input. The problem with this circuit is that somehow I can hear capacitors discharging or something similar https://vocaroo.com/i/s1U2NhEnlQaa. I have also started to believe that some kind of aliens are trying to communicate with me when I am touching the board https://vocaroo.com/i/s0wLsUYS8Rym. How can I "cut" these peaks and prevent aliens interrupting to my signal?
