V‑Blaze’s redaction options can remove sensitive numeric information from both transcripts and audio. When transcript redaction is activated by setting the scrubtext parameter to true , all instances of sensitive numeric digits will be replaced by the hash sign (#).

When audio redaction is activated by setting the scrubaudio parameter to true , all audio segments containing sensitive numbers are replaced by silence. When using audio redaction, results are automatically returned as a ZIP archive containing the transcript and purified WAV file.

For example, to submit the file "sample1.wav" for transcription with both transcript and audio redaction activated, use a command like the following:

curl -F scrubtext=true \
     -F scrubaudio=true \
     -F file=@sample1.wav \
     http://vblaze_name:17171/transcribe \
     -o results.zip

The response to this POST will be a ZIP file that contains both "sample1.json" and a redacted version of "sample1.wav".
