What is speaker impulse response?

An impulse response (or IR) is a sonic measurement of the sound of a speaker, room or microphone in relation to a sound source.

Can impulse response make the frequency response?

The impulse response is the response of a system to a single pulse of infinitely small duration and unit energy (a Dirac pulse). The frequency response shows how much each frequency is attenuated or amplified by the system. The frequency response of a system is the impulse response transformed to the frequency domain.

How is speaker impulse response measured?

The simplest way of measuring an impulse response is often the use of an impulsive source signal such as a clap of your hands, a balloon or a blank pistol. By selecting External Impulse, the response to an impulsive signal is simply recorded without any subsequent processing.

How do you EQ a loudspeaker?

First, position speakers for best sound. Next, set equalizer controls to neutral or 0 before adjusting to your listening preference. For brighter treble, reduce mid-range and low-end frequencies. For more bass, tone down treble and mid-range frequencies.
