Summary

Analyze a binary audio input to detect silence segments and classify the audio for near-silence or no-dialogue conditions using FFmpeg's silencedetect filter.

Inputs

  • Input Data Field Name (required) — Specify the binary field name that holds the source audio file; defaults to 'audio'.
  • Options — Configure analysis parameters including timeout (ms), silence noise threshold in dB, and minimum silence window length in seconds.

Output shape

a list of items each containing original JSON and binary data with added fields

Each output item JSON includes 'audio_guard_status', 'audio_guard_reason', 'audio_duration_seconds', 'audio_silence_ratio', and 'audio_analysis_version' fields that summarize the silence analysis results or failure reason; binary data is passed through unchanged; processing respects 'continueOnFail' settings to handle errors.
