​
Overview

Evaluates speech clarity and background noise levels in the audio.

​
Configuration

This detector does not accept configuration keys.

​
Example Configuration

{
  "detector_name": "audio_noise",
  "config": {}
}

​
Result Schema

{
  "detector_name": "audio_noise",
  "pass_check": true,
  "score": 0.86,
  "rationale": "Good SNR: 18.4 dB. Low music overlap: 6.0%",
  "metrics": {
    "snr": {
      "snr_db": 18.4,
      "speech_rms": 0.12,
      "noise_rms": 0.03,
      "usable_noise_duration_sec": 8.2,

  }
}

​
Interpreting Results

  • snr.pass/music.pass: Individual checks that determine the overall pass/fail result.
  • snr_db/overlap_pct: Primary quality signals for speech clarity and music overlap.
  • speech_segments_count/total_speech_duration_sec: How much speech was detected.
