Hi @建设,

I understand that the issue here is the Audio Toolbox is listed under the account license and MATLAB is activated successfully, but Audio Toolbox features are not available after installation, as shown in the screenshot.

For Audio Toolbox licensing, the feature name used in the license file is "Audio_System_Toolbox". To confirm that the license is correctly recognized by MATLAB, you can test it directly from the Command Window using the following command:

license("test","Audio_System_Toolbox")

If this command returns false, it indicates that MATLAB is not currently able to check out the Audio Toolbox license.

Regarding the script you mentioned, I am also unable to find a documented Audio Toolbox function or example related to "loudnessZwicker". It is possible that this function comes from a custom implementation or from another toolbox.

To verify that Audio Toolbox is working correctly, I recommend testing it with some standard Audio Toolbox workflows, such as basic audio input and output examples. The following page provides simple, supported examples that can help confirm correct toolbox functionality:

I hope this helps!
