Have you ever played a video that doesn't quite have the audio in perfect sync? If so you'll know its really annoying and makes a film or movie virtually unwatchable but thanks to VLC Player, there's a very easy solution.

VLC Player is unusual in that it allows you to change the position of the audio over the video. All you need to do is press the G and F keys while the video is playing.

"G" moves the audio forward:

"F" delays audio:

An Audio delay indicator shows you by how many milliseconds you have moved the audio forward or back after pressing the keys.

However, using the keys only allows you to move the audio in increments of 50 miliseconds. If you want to move it more precisely, then you have to go into VLC's Preferences.

In Preferences select Audio:

Change the box in the bottom left from Basic to All. Now you have access to the advanced preferences where you should see a value called Audio desynchronization compensation:

Simply change this to the exact value that you want (in this case 10) and the audio speed will change instantly.
