v1.7.3 - Professional Audio Mixing

🎉 vot-cli-live v1.7.3 - Professional Audio Mixing

🎚️ Major Audio Quality Update!

This release brings professional-grade audio mixing to vot-cli-live!

🔥 What's New

1. Improved ffmpeg Profile 🎧

Old approach (volume):

[0:a]volume=0.3[a1];[1:a]volume=1.5[a2];[a1][a2]amix

• ❌ Risk of clipping (audio distortion)
• ❌ Uneven volume throughout video

New approach (weights + dynaudnorm):

amix=weights=0.3 1.5[m];[m]dynaudnorm=framelen=30:gausssize=31:maxgain=12

• ✅ Mathematically correct mixing
• ✅ Automatic volume leveling
• ✅ No more volume jumping!

2. Dynamic Audio Normalization 🔥

Without dynaudnorm:
Volume: ▁▁▁▃▃▃█████▃▃▁▁▁  ← constantly adjusting

With dynaudnorm:
Volume: ▅▅▅▅▅▅▅▅▅▅▅▅▅▅▅  ← consistent! 🎧

Benefits:

• Set volume once and forget it
• Comfortable listening experience
• Professional sound quality

3. New Parameter: --normalize-audio

# With normalization (default, recommended)
vot-cli-live --output="." --merge-video "URL"

# Without normalization (faster, but may need manual adjustment)
vot-cli-live --output="." --merge-video --normalize-audio=false "URL"

📦 Installation

npm install -g vot-cli-live

🚀 Usage

# Basic usage (normalization enabled by default)
vot-cli-live --output="." --merge-video \
  --original-volume=0.3 \
  --translation-volume=1.5 \

📝 Technical Details

• Performance: ~10% slower with normalization (worth it!)
• Quality: Professional-grade audio mixing
• Compatibility: Works with all supported platforms
