What audio indication must be provided in sound recordings of classified information?

The requirement for an audible statement of classification and dissemination controls in sound recordings of classified information is key to ensuring that those who access the recording are immediately aware of its sensitivity and handling instructions. This audio indication serves as a clear alert to anyone who listens to the recording, emphasizing the importance of adhering to established policies for protecting classified material.

In the context of classified information, it is vital that the classification level (such as Confidential, Secret, or Top Secret) is understood by any potential listener right from the outset. Additionally, providing dissemination controls informs listeners of any restrictions on sharing or distributing the recorded information, thereby safeguarding national security interests. This measure is a critical part of compliance with government regulations regarding the handling of classified materials, ensuring that all personnel recognize their responsibilities in protecting such information.

While the other options may provide useful information, they do not fulfill the specific requirement to alert listeners to the classification status and required handling of the recorded content.
