FSBTool error while trying to import AudioSource. How to fix?

Hello, I’m getting error when trying to insert audio in my project.

Errors during import of AudioClip Assets/Sounds/cat.mp3:
FSBTool ERROR: Failed with error code c00d36e3
FSBTool ERROR: Failed encoding audio clip ‘Assets/Sounds/cat.mp3’ to AAC. Possibly the file is too short. Try to append silence such that the length becomes greater than 256 samples.

Does anyone know how to fix it and what the problem is?

It may be due to you don’t have ffmpeg installed. Try this below command on your terminal for install it

sudo apt-get update && sudo apt-get install -y ffmpeg

After successful installation go to your unity project and re-import all audio clip assets. it should work now
