If your audio is playing but you can’t see the audio waveforms in Premiere Pro, you need to clear your Cache files.
How to make audio waveforms visible?
When you import a video file with audio attached, Premiere Pro generates media cache files to display the waveforms. However, if these files become corrupted or your cache storage is full, Premiere Pro might fail to generate waveforms correctly.
Step 1: Clear Media Cache Files
For Windows Users:
1. Go to Edit > Preferences > Media Cache.
2. Click Delete next to “Remove Media Cache Files.”
For Mac Users:
1. Go to Premiere Pro > Preferences > Media Cache.
2. Click Delete Unused Media Cache Files.
> Tip: Deleting cache files will not affect your projects. Premiere Pro will regenerate them as needed.
Step 2: Restart Premiere Pro
After clearing cache files, close Premiere Pro completely and restart it. This allows the software to regenerate new media cache files for your current project.
Step 3: Open Premiere pro
If you re-open your Premiere Pro again, the waveforms will be generated. Make sure when you closed it before, it was quitting it fully not just closing it.
Step 4: Adjust Automatic Cache Deletion Settings
To prevent this issue in the future:
1. Go to Preferences > Media Cache.
2. Enable “Automatically delete media cache files older than 30 days.”
3. This ensures Premiere Pro clears old cache files periodically.
