Audyssey ACM1-X individually calibrated microphone for MultEQ-X

Audyssey Laboratories, Inc.: The Audyssey ACM1-X is an individually calibrated microphone designed for room measurements with Audyssey MultEQ-X. Its mic-specific calibration file is used by the Windows software, so this is a specialised choice for compatible AVR calibration rather than a general-purpose measurement microphone.

At a glance

Each microphone is described as individually measured and assigned its own calibration file.
The manufacturer says the file is supported in MultEQ-X software on Windows 10 and 11.
Omnidirectional pickup is intended to capture room sound from all directions for acoustic measurements.

Pros and cons

Pros

Individual calibration data is designed to correct measurements towards a Type 1 reference microphone.
The omnidirectional pattern suits capturing room acoustics from multiple directions.
Customer feedback reports positive calibration results and perceived sound improvements.

Cons

Its calibrated workflow depends on MultEQ-X, rather than the AVR's built-in calibration or the mobile MultEQ Editor app.
A paid MultEQ-X licence for a compatible AVR is required, adding a software cost beyond the microphone.

What to know before buying

The calibration file is described as usable only within MultEQ-X. The manufacturer says using this microphone with an AVR's built-in calibration, the mobile MultEQ Editor app or other measurement software will not provide the stated file-based correction. Confirm that your AVR is compatible with MultEQ-X before purchase.

Who is it for?

A good fit for

Owners of a compatible AVR who plan to calibrate through MultEQ-X on a Windows 10 or 11 computer.
Buyers who want a microphone-specific calibration file for room-acoustic measurements.

Less suited to

Those seeking a microphone for singing or general-purpose recording, despite the listing's recommended-use field.
Buyers who intend to use only an AVR's built-in calibration or the mobile MultEQ Editor app.
Users who need a microphone supported by measurement software other than MultEQ-X.

Customer feedback is positive about microphone performance, sound quality and calibration results, with reports of perceived improvement over standard microphones. That feedback is relevant to the ACM1-X's room-measurement purpose, but the reported experience does not replace the key compatibility requirement: its individual file is intended for MultEQ-X. Aggregate ratings are generally favourable, though they do not establish that every user will see the same results.

Frequently asked questions

Does the ACM1-X work with an AVR's built-in calibration?

The manufacturer says its individual calibration file is not used by the AVR's built-in calibration. The specified workflow is MultEQ-X software.

What else is required to use the calibration file?

The listing says to use MultEQ-X on Windows 10 or 11 and requires a paid licence for a compatible AVR. The software is available from the Microsoft Store with an in-app purchase.

Can I use it with the mobile MultEQ Editor app?

The manufacturer states that using the ACM1-X with the mobile MultEQ Editor app will not provide the individual-file correction described for MultEQ-X.

Is the calibration file supported in other measurement software?

The listing says the file is currently supported only within MultEQ-X, and use in other measurement software is not supported.
