LumaFusion Audio Missing After Export

Workaround available iPad, iPhone, Mac Updated October 21, 2026

Quick answer

A known LumaFusion bug drops audio from exports when the Sound Isolation preset's Sound To Isolate setting is High Quality Voice. Change it to Voice and export again.

Most likely fix: Switch Sound Isolation to Voice.

Symptoms

The project plays with sound in the editor, but some or all audio is silent in the exported video. Some users also hear clipping only in the export.

Why it happens

  • Sound Isolation preset set to 'High Quality Voice' (known issue under investigation)
  • Audio levels peaking above 0 dB that only clip after export

How to fix it

Try these in order — the most common fix is first.

  1. 1. Switch Sound Isolation to Voice

    1. Select the clip with the Sound Isolation preset
    2. Open the audio effect settings
    3. Change Sound To Isolate from High Quality Voice to Voice
    4. Export again

  2. 2. Lower levels to stop clipping

    1. Check the audio meters while playing
    2. Reduce clip volume so peaks stay below 0 dB, then re-export
