Can this skill handle EBU R128 loudness normalization?

Yes, it provides comprehensive workflows for single-pass and two-pass EBU R128 normalization, ensuring broadcast compliance for TV and streaming.

How does it handle Windows file paths?

The skill is strictly optimized for cross-platform use, ensuring backslashes are used for Windows file paths during all edit and write operations.

Does it support extracting audio without re-encoding?

Yes, it includes specific commands to copy audio streams directly from video containers (using -c:a copy) to preserve original quality.

Can I use this skill for batch processing multiple audio files?

Absolutely. It provides shell script patterns and FFmpeg-specific logic for processing entire directories of audio files simultaneously.

Is there support for noise reduction and EQ?

Yes, the skill covers high-pass/low-pass filters, multi-band equalization, and FFT-based noise reduction techniques (afftdn).
