Looking for advice to extend the loop of Sniper Elite 5 music.

I'm looking for an advice on how to get around this issue.
Via quickbms I managed to reimport the main menu music and it worked as expected, but didn't put into account the fact that the devs have chose to make the audio file only playing half the audio file. Any advice on how to extend the playtime length? The game uses Asura Engine.
