Audio Unable to import audio

Hello everyone. So I am trying to import an audio file into my Unity project (version 5.6.1) on Mac, but every time I import an audio file (either .wav .mp4 or .ogg), I am unable to put the file in audio sources. When I look on the console, I am presented with an error that states:

Errors during import of AudioClip (name of audio clip)
FSBTool ERROR: Failed decoding audio clip.

Can anyone help me with this??? I am trying to add background ambience to my world.

 

Your Unity version is very much out of date. Can you open the audio file in another program like VLC player or QuickTime? Check the encoding/bitrate other data to make sure it's compatible. For the record, you can't just change the extension and expect the file to change types if that's what you were doing, you have to go through an export process in some program to translate into the new file.
