Measurement
This section explains the measurement portion of
AutoEQ.
Microphone movement
Correct microphone movement during sound
measurement is critical to getting a good result from
AutoEQ. Please read this section carefully.
1
Overview
To make a measurement, you will move the
microphone through the space of the cabin while
AutoEQ plays a frequency sweep ("whoop-whoop"
sound).
The key is to move the microphone constantly and
consistently so that all of the space in the cabin is
evenly covered during measurement.
This is important, so we will explain it in detail.
2
Measurement points
One AutoEQ measurement consists of at least 200
measurement points. That is, the frequency sweep
("whoop-whoop") will be played 200 times in order
to measure the cabin's sound.
The exact point in space where the microphone is
when it hears one frequency sweep is a
measurement point. The sound was measured at
that point.
The goal of microphone movement is to space these
measurement points as evenly as possible in the
frontal space of the car cabin.

Range of movement
Spaces through which you should move the
microphone include:
• The space above the dashboard.
• The space in front of the driver and passenger, as
low as the front of their shins (going slightly into
the foot wells) and as high as the ceiling.

What to avoid
When moving the microphone for a measurement:
• Do not stop moving the microphone at all,
including for individual measurement points.
Constant movement is best.
• Do not go deep into the foot well spaces in the
measurement.

Perform measurement
When you are ready, click the button to begin
measurement.
A countdown will begin on the screen, and then the
measurement process will begin.
For the duration of the measurement, move the
microphone through the cabin of the car as
described in the previous section.
During measurement, the result of each sweep will
be displayed on the screen with a faint curve and
the average will be shown with a strong curve.

measurement in progress.
The progress of the entire measurement will be
shown in a progress bar at the bottom of the screen.
The app will confirm when measurement is
completed.

measurement that has been completed.
If you see no obvious problems with the
measurement, you can accept it. If not, choose
"remeasure" to retry measurement.
