2. Product identification

This Manual applies to SoundID Reference Measurement Microphone (2021) ("Product"). The Product can be identified by the profile number ("Profile ID") associated with the individual microphone calibration profile ("Microphone Profile"). The Profile ID is printed on the measurement microphone ("Microphone") product element. Learn more in Section 7.1.

The Product can be identified by Profile IDs between 36K019-38L193 in alpha-numerical order. 

For other (older/newer) Sonarworks microphone products with a Profile ID outside the 36K019 - 38L193 range, see these user manuals:

3. Product documentation

The latest version of the documentation is available under the Legal page on the Sonarworks website. Supplementary documentation is available under the Support, Resources, and Downloads pages:

4. Intended use and reasonably foreseeable misuse

The Product is intended to be used as a tool for making high-precision measurements of acoustic sound pressure and acoustic pressure differences within the audible frequency spectrum of 20Hz to 20kHz.

The Product shall be used with the following software and components only:

6.5. Operating panels

The interface of the Microphone consists of a single male XLR connector, to be used as a point of connection between the Microphone and a peripheral audio interface. The Microphone XLR connector is intended to be connected to a balanced XLR female connector only.

6.6. Product compliance

This product complies with all relevant European Union Directives and the following relevant product safety standards:

While using the Microphone, magnetic fields generated by other electronic devices may induce non-destructive noise on the Microphone capsule. The distortion introduced by electromagnetic fields is not damaging to the Microphone or the accuracy of the intended acoustic measurement: Product performance deviations and performance thresholds are accounted for when used with the SoundID Reference software ("Sonarworks-native use").

7. SoundID Reference Microphone Profile

7.1. Microphone Profile and Profile ID

The frequency response of each Microphone unit has been individually measured, and a unique Microphone Profile is provided containing the measured frequency response data. The individual Microphone Profile is associated with a Profile ID, printed directly on each Microphone unit, as shown in Figure 5 below:

Figure 5: Microphone Profile ID (example)

Each Product unit includes a unique Microphone Profile, associated with three separate profiles to be used for various angle measurements:

For Sonarworks-native use, the SoundID Reference Measure application ("Measure app") employs the 30° profile for 2.0 stereo configuration measurements, while 2.1-9.1.6 multichannel configuration measurements employ both 30° and 90° profiles. 

7.2. Sonarworks-native use

To achieve optimal results with Sonarworks-native use of the Product, the Microphone Profile must be employed during the measurement process:

Once the Microphone Profile is loaded in the Measure app (see example below), the correct angle profile(s) are applied automatically, based on the configuration selected during a previous step in the Measure app.

7.3. Microphone Profile downloads

For offline use, third-party software/hardware use, or general backup purposes (in accordance with Section 4), the Microphone Profile files can be downloaded in a ZIP archive from the Sonarworks website:

1.

Go to the Downloads page on the Sonarworks website: https://www.sonarworks.com/soundid-reference/download

2.

Navigate to the "Measurement microphone profile downloads" section.

3.

Enter the Microphone Profile ID and click on the 'Download profile' button.

4.

Extract the downloaded ZIP archive to access the Microphone Profile files.

The download will contain two files in the Sonarworks-native SWMIC file format and three files in TXT file format for third-party use:

7.4. Offline and third-party use

For Sonarworks-native offline use, the Measure app allows for the Microphone Profile to be loaded manually, in case there is no internet access on the computer ("Machine") used for the measurements at the given moment:

Note: For Sonarworks-native use, 2.1-9.1.6 multichannel measurements require both 30° and 90° profiles to be used, which can only be done by entering the Profile ID in the Measure app as described in Section 7.2. Loading only the 90° TXT file manually will result in reduced measurement accuracy.

For third-party use, the Microphone Profile files can be downloaded and employed in TXT file format as described in Section 7.3.

Note: Sonarworks is not responsible for any compatibility-related issues assiocated with third-party use of the Microphone Profile. It is the user's responsibility to resolve any such issues according to the third-party software/hardware legal guidelines, documentation, and other sources of information.
