Audio Mixing Patterns

Comprehensive guide to audio mixing for video production using ffmpeg. Covers narration/music balancing, automatic ducking, timing control, and loudness normalization.

Core Principle

Quality Audio = Clear Narration + Supportive Music + Appropriate Levels

The human voice occupies 85-255 Hz (fundamental) with harmonics up to 8kHz. Music must support, not compete.

Volume Balancing Formula

Standard Video Mix Ratios:
--------------------------
Narration:  100% (reference level)
Music:      15-20% of narration level
SFX:        70-100% of narration level (contextual)
