ffmpeg-ambient-audio

What problem does it solve?

This skill generates subtle, loopable ambient background music for tutorials and animations directly with FFmpeg, eliminating the need for external audio files or Python audio libraries.

Core Features & Use Cases

• Generate a 15-second layered ambient loop using FFmpeg's aevalsrc with precise harmonic components and exponential decay.
• Extend the loop to match your video duration by streaming or looping the generated clip.
• Mix the ambient track into video with optional fades and stereo balancing, and verify the output with ffprobe.
• Real-world use: background music for tutorials, animations, and screencasts that require non-intrusive audio.

Quick Start

Run the provided FFmpeg commands to generate a 15-second ambient loop, extend it to your video duration, and mix it into your video project.
