# 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

- 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.

## Before you buy

- 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.

## In the box

- Microphone (Included)

## 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

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.
- Positive themes: Customers report positive microphone performance and calibration results.
- Positive themes: Customer feedback describes sound quality and perceived improvements over standard microphones.

## 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.
