Cannot Import audio

I am having issues importing audio files to UE4.8 (SOURCE) I have tried both WAV And MP3S

Mp3s get not compatible error
and WAVS Get an import error

Have you exported the WAV file as 16 bit PCM?

I don’t know,

edit Iv just checked and i have just check and i had set my converter for PCM 32BIT

Thank youfor you time

I had problems with importing audio until i exported it properly with that setting from audacity.
