Get a music editing sftware, eg. Adobe Audition, and open the music file you want to loop. You need to have a basic understanding of how to read audio waves, but this comes quite easily by listening to the audio file while watching which particular part of the wave is being played. Focus on where a certain part of the beat is, and what it looks like... I use the snare. Then highlight the wave from just before the peak which represents the snare (zoom in to increase the accuracy) and highlight it up untill just before the snare peak at whichpoint you want the loop to end. Then, while the certain part of the beat is highlighted, click the button neer play which looks like an '8' sideways, this will loop the selected area, so you can check if it sounds right. If it sounds a little off, you can change the selected area accordingly. If it sounds right, which it should if you have followed instructions correctly, then right click the selected area and go down to "Copy to new" and click it... this will open a seperate wave containing only the highlighted area. Then simply copy and paste the wave so it loops.
Hope that is clear, give it a try and if you have any problems, post them here and I'lkl see if I can help any further.:thumb:
