Hi ^^
I need your help cause I have a weird problem with audio import. It seems that when I import very short loop (between 0 and 1 seconds) , the end of the sound magically come to the beginning of the sound. Here’s an example :
image unity
But in audacity the audio seems just fine :
image audacity
I had the same problem. Since I needed a quick solution I added a few hundred samples of silence at the end of the clip as a workaround. Then the import worked for me. Nevertheless I think we should file a bug report for this.
Thanks for the help ! Worked for me too. And yes it would be great to file a bug report but that’s strange nobody did it before =/
Great 
I just looked at the issue tracker and found that this bug is already reported.

Hi again ^^
The problem has just vanished lol
The sounds were in .wav and automatically compress to mp3, but when I relaunched the Unity Editor yesterday, the files was compressed to vorbis and there were no more bug.
That’s weird because the compression format was already on vorbis when I imported the files the first time
Well seems that it happens just with short sounds in mp3 format for me too. Unfortunately I can’t use another compression format. 
I don’t really understand how I changed the compression format cause it was on vorbis the whole time.
It just changed when I tried to manually modify the compression format in some .meta files which are created when you import a file or multiple files.
I changed the first line to a random number, maybe that’s the way to force the compression format to change?
