MUIC & ACOUTIC – AUDIO IGNAL PROCEING & DP CALCULATOR
Crossover Slope
A precise tool.
What is the Crossover Slope & How does it work?
Crossover filters are essential in audio signal processing to separate different frequency bands. The slope of a crossover filter determines how steeply the energy is attenuated as it transitions from one band to another.
The order of a crossover filter determines its slope, which is measured in decibels per octave (dB/oct). A first-order filter has a 6 dB/oct slope, a second-order filter has a 12 dB/oct slope, and a fourth-order filter has a 24 dB/oct slope.
Slope (dB/oct) = Order times 6
Order = Filter order (1, 2, or 4)

Frequently Asked Questions
What is the slope of a first-order crossover filter?
A first-order crossover filter has a slope of 6 dB/oct.
How do I calculate the slope for a fourth-order crossover filter?
Multiply the order by 6, so a fourth-order filter has a slope of 24 dB/oct.
Can you explain what decibels per octave (dB/oct) means in audio processing?
dB/oct measures how quickly sound energy is reduced as it moves from one frequency band to another.
What is the slope of a second-order crossover filter?
A second-order crossover filter has a slope of 12 dB/oct.
How does increasing the order of a crossover filter affect its slope?
Increasing the order increases the slope, with each order adding 6 dB/oct to the total slope.
Is there a formula to calculate the slope from the order of a crossover filter?
Yes, the formula is Slope (dB/oct) = Order × 6.
What are some common orders for crossover filters in audio equipment?
Common orders include first-order (6 dB/oct), second-order (12 dB/oct), and fourth-order (24 dB/oct).
