Great AI porn videos are incomplete without sound. VirtuaVixen offers two audio workflows that add realistic sound to any video — whether it was generated with WAN 2.2, LTX 2.3, or any other tool.
Two Ways to Add Audio
1. MMAudio (Add Audio)
MMAudio is a general-purpose AI audio generator that analyzes your video and generates matching sound effects at 44kHz. It picks up on visual cues — body movement, skin contact, facial expressions — and creates appropriate audio.
- Works with any video source — WAN 2.2, LTX, or even uploaded clips
- Generates: Moaning, skin slapping, ambient room sounds, breathing
- Best for: Adding sound to existing WAN 2.2 videos that don't have audio
2. LTX2 Audio
The LTX2 Audio workflow uses the LTX-Video model's native audio capabilities to generate and sync sound with video content. It's tightly integrated with the LTX pipeline for more precise audio-visual sync.
- Tighter sync — built into the LTX model architecture
- Best for: Adding audio to LTX-generated videos or when you want precise sync
Recommended Pipeline
- Generate your starting image with a T2I workflow
- Animate it with WAN 2.2 (for LoRA control) or LTX 2.3 (for built-in audio)
- If using WAN 2.2, add sound with MMAudio or LTX2 Audio
Note: LTX 2.3 workflows already include native audio — you only need a separate audio step for WAN 2.2 or other silent video sources.
