🚀 Key Capabilities & Forensic Engine

• 5-Stage Sequential Audio DSP Pipeline:
  • Sub-rumble highpass filter ($<80\text{ Hz}$, 12 dB/oct roll-off).
  • Corona discharge impulsive de-clicking (adeclick).
  • Broadband induction spectral denoising (afftdn, $\text{nr}=12\text{ dB}$, $\text{nf}=-40\text{ dB}$).
  • High-$Q$ surgical harmonic notch rejection ($Q=30$ at 60 Hz, 120 Hz, 180 Hz, 240 Hz).
  • Trailing silence container padding (apad + -shortest).
• Lossless Stream Passthrough: Bit-for-bit video muxing (-c:v copy) preserving all 39,069 original 1080p camera frames without re-encoding.
• POSIX & macOS Compatibility: Single executable Bash 3.2+ CLI with groff manual page (fix_video.1).
• Empirical Transcript Diffing Tool: Python helper (compare_transcripts.py) measuring speech-to-text word error rates.
