Q Factor Calculator

Formula

The formula to calculate the Q Factor (Q) is:

\[ Q = \frac{f_c}{BW} \]

Where:

\( Q \) is the Q factor of the EQ band.
\( f_c \) is the center frequency (Hz).
\( BW \) is the bandwidth (Hz).

Example

Let's say the center frequency (\( f_c \)) is 1000 Hz and the bandwidth (\( BW \)) is 200 Hz. Using the formula:

\[ Q = \frac{1000}{200} \]

We get:

\[ Q = 5 \]

So, the Q Factor (\( Q \)) is 5.

What is a Q Factor?

The Q factor, or quality factor, is a dimensionless parameter that describes how underdamped an oscillator or resonator is, and characterizes a resonator’s bandwidth relative to its center frequency. Higher Q factors indicate a narrower bandwidth, with a more selective and less damped resonator. In audio equalization, a higher Q factor means that the EQ will affect a smaller range of frequencies around the center frequency, allowing for more precise control over the sound.
