How should an audio recording containing both unclassified and confidential information be marked?

An audio recording that contains both unclassified and confidential information requires clear marking to ensure that listeners can discern the classification status of the information being presented. Stating the classification before each piece of information ensures that there is no ambiguity regarding the sensitive material contained within the recording. This approach allows for proper handling and safeguarding of classified information, ensuring that personnel are adequately informed about the sensitivity of the content at all times.

This method is essential in maintaining compliance with regulations surrounding the protection of classified data, as it actively informs the user of the classification status throughout the recording. By indicating the classifications before each segment, it avoids potential mishaps that could arise from misinterpretation of the material. This ensures that anyone listening is made aware of which portions of the audio are confidential and which may be considered unclassified.
