Audio and video can be more engaging formats than written content, and often convey layers of emotions and nuance that text fails to capture.
Audiovisual media are getting popular in every industry, including legal, medical, and research. However, they pose a challenge to protect sensitive information sometimes required by law, such as personally identifiable information (PII).
While it may be easy to find, select, and strip out sensitive information from a text document, audio files are much more complex to edit. Given that, redacting PII from audio, and from the audio track of video files, can be challenging.
In this article, I will provide an overview of what audio redaction is, its benefits, and how you can redact sensitive information from your audio files just by selecting text 🤯.
