An error while importing any audio file?!

I cannot fix this, tried everything I could find on the web:
- modifying dates fix
- deactivating anti-virus and firewall
- exporting via Audacity in all supported formats
- reducing audio quality within Unity
- using notepad++ to edit the audio file, hitting the spacebar at the start, then reverse, saving

Using Unity 5.5.4p4 on Windows 7.

I get this error:

Errors during import of AudioClip Assets/cityambience1.mp3:
FSBTool ERROR: Could not find encoder library 'libvorbis.dll', please copy it from the FMOD SDK to the application directory.
FSBTool ERROR: Encoder initialization failed.
FSBTool ERROR: Encoder initialization failed.

I found the libvorbis.dll in the FSBTool folder, tried the above, doesn't work. Cannot find the FMOD SDK, doesn't exist.

Any help would be appreciated. I was very motivated to begin with creation of my 2D game, (aiming to do a really short demo) but, very demotivated after hours of internet search and no solution.

After some workaround tries, the problem was solved (for me at least) by replacing DLL's from Unity 2017.1 at that path: [PATH_TO_UNITY]\Editor\Data\Tools\FSBTool
