What is potentiometer taper?
Simply put, a potentiometer is a resistor. When you turn the pot, you change the level of resistance. A potentiometer taper is the relationship between the position of the pot (as you turn it) and the corresponding output. This is important when using an audio potentiometer as a volume knob because humans perceive volume changes logarithmically. This means that if you use a logarithmic pot (type A), the volume sweep is evenly distributed through the rotation of the knob. In contrast, if you were to use a linear pot (type B) for volume control, most of the volume changes will be "crowded" at one end of the turn. The "reverse log" (type C), also called a reverse audio taper, is like an A taper, only backward.
