Comb filtering occurs when two or more identical audio signals are mixed together with a slight delay between them. The resulting frequency response graph resembles a comb because frequencies that are in phase sum together, while frequencies that are out of phase cancel.

What is a comb filter effect?

What Is Comb Filtering? Comb filtering is a phenomenon that happens when the same sound arrives at the listener's ears (or a microphone) at different times with a very small delay between the signals. This delay can be anywhere from one sample to several milliseconds, up to 15ms–20ms.

These two audio waves are identical and perfectly in sync or in phase.

Is comb filtering the same as phase?

Comb filtering creates peaks and troughs in frequency response, and is caused when signals that are identical but have phase differences — such as may result from multi-miking a drum kit — are summed. An undesirably coloured sound can result. The same effect can be harnessed deliberately to create flanging effects.

When can comb filtering occur?

Comb filtering occurs when a sound adds to itself within a short time interval. This interval typically ranges from less than one ms to approximately 25 ms.

How do reflections cause comb filtering?

Comb Filtering caused by Sound Reflections As reflected sounds travel a further distance than the direct sound, they arrive at our ears or at a microphone later. Both signals are identical, but one signal is delayed by a few milliseconds, causing a comb filter, where some frequencies are cancelled and some are summed.

What is comb filter speaker?

Comb Filtering: This is basically a delayed version of a primary signal that is produced when two or more loudspeakers are playing the same signal at different distances from the listener. In any enclosed space such as a music or theater room, listeners hear a mixture of direct and reflected sound.
