Mix background music under a video's voice with automatic ducking. The video's own audio (voice/dialog) drives FFmpeg's sidechain compressor, so the music dips while speech plays and recovers in pauses — the standard treatment for shorts, reels, and podcast clips. Args: input_path: Video whose existing audio drives the ducking. music_path: Background music or ambience to mix underneath. output_path: Where to save the result. Auto-generated if omitted. music_volume: Base music level before ducking (0-2, default 0.6). threshold: Sidechain level above which ducking engages (0-1). ratio: Compression ratio applied while voice plays (1-20). attack: How fast the music dips, in milliseconds (1-2000). release: How fast the music recovers, in milliseconds (1-9000).
