'Pop' noise when looping [SOLVED]

[Trebor]

… The software allows you to use mp3 sound clips in your game, and has a ‘loop’ feature for when you want the sound playing continuously … However, when the clip comes to an end, then starts the loop again, there’s a very noticeable ‘pop’ of silence between it ending and starting up.

When you make an MP3 in Audacity a ~1/20th of second of silence is inserted at the start.
Using WAV solves the problem : silence not inserted, and seamless looping is possible.
