sound looping problem

[titangate]

here i grabbed a looping sound effect, recoded into ogg.
however, i used source:setLooping and played it, and there's this very noticeable interval of silence before the sound get replayed.
i tried using another platform(mac/windows), tried other formats, but the problem remained still.
does this has anything to do with love itself, my method of playing this thing, or something wrong with the sound file itself?(i tend not to think this way because when i use garageband i can make the two files play continuously)
thanks in advance.

It's in the sound file. Use this one:

could you tell me what method/software did you use to get rid off it? i can look at it myself next time if this happen again.

For soundwave edition and things like removing silences, I use Audacity.

Yep, I used Audacity. If you run Ubuntu, it's in the Software Center.
