LTX-2 Video with Audio | Generate Synchronized Sound (Music, Ambience, Voice)
Create LTX-2 video with sound. Learn audio modes, how to describe music, ambience, and voice, plus tips for better sync and clean mixes.
Audio can make LTX-2 video feel finished. This guide shows how to describe sound in plain language and keep it aligned to the visuals.
Use these tips when you enable audio in the LTX-2 video generator so your mix stays simple and synced.
What audio sync means in practice
When audio is enabled, you are guiding:
- What you hear (music, ambience, voice)
- When it happens (timing aligned to visual events)
- How it feels (mood, intensity, rhythm)
Even simple cues can noticeably improve perceived quality.
Recommended audio modes
If you control the UI, these three modes cover most users:
- Ambience only (safe default)
- Music and ambience
- Voice, music, and ambience (advanced)
How to prompt audio (simple and effective)
Avoid technical jargon. Write like a director:
Ambience examples:
- "Soft city night ambience, distant traffic"
- "Gentle ocean waves and seabirds"
- "Quiet indoor room tone, subtle air conditioner hum"
Music examples:
- "Warm lo-fi beat, slow tempo, mellow"
- "Epic orchestral swell, cinematic trailer feel"
- "Minimal ambient pads, calming meditation"
Voice examples (if supported):
- "Calm female voice, friendly tone, short line: 'Welcome to the future.'"
- "Excited narrator voice, energetic pacing, one sentence."
Tip: If voice is enabled, keep it short. Long scripts increase the chance of pacing issues.
Timing tips for better sync
Audio feels synced when your prompt includes events:
- "A ceramic clink when the mug touches the table"
- "Footsteps as the character walks"
- "A whoosh as the camera passes by"
One or two event cues can greatly improve perceived alignment.
Clean mix checklist
- Start with ambience only
- Add music next
- Add voice last
- Keep loudness consistent with presets (for example, "Balanced mix")
Troubleshooting audio
Music overpowers ambience
Fix: choose an ambience-forward mix or use softer language like "minimal" or "gentle."
Voice pacing feels off
Fix: shorten the script, specify "slow and clear," reduce duration, or use voice only.
Audio feels disconnected from visuals
Fix: add one or two explicit sound events aligned to actions.
FAQ
Q: Do I need audio for every LTX-2 video?
