How to manually remove identifying information from audio


CaseGuard Studio’s Manual Audio feature gives you complete control when redacting sensitive information from any file with audio. You can conceal Personally Identifiable Information (PII), classified information, or other sensitive content with just a few clicks. It is ideal for investigators who need to perform manual edits on their files after performing many redactions!

For example, Investigators with the need to redact phone calls or Interviews find CaseGuard Studio’s manual audio redaction reliable and user-friendly. In seconds, you can redact any (PII) within an audio file. Additionally, within Caseguard, you can anonymize any voice by adding the “Change Voice” effect which lets you choose from 10 different pitches. While the redaction tool is phenomenal, the “edit” option is available for those looking to hide the identity of the speaker without performing any redaction.

In addition to applying redactions, you can:

  • Add a redaction reason on each audio point, if the court requests.
  • Anonymize audio points to hide the identity of the speaker to comply with privacy laws.

  • While all four methods are applied differently, they are all manual options!
  • Additionally, you can apply the same effect on multiple files within one project, using the Copy Effect function.
    • You can use the copy effect to redact multiple audio files to ensure the same effect, shape, color, and/or redaction reason is applied to all redactions in the audio files.
  • From the Reason dropdown menu, a redaction reason can be selected for each audio redaction point or a new reason can be added by clicking icon-edit-redaction-reasons next to the dropdown.
  • Once you have reviewed the redactions, click Export Icon Export from the Task List Panel or the Export icon from the Shortcuts Bar to export your redactions.
