Looping songs at a certain point?

You have to first make a song into an .OGG format. Several programs can do this, like Audacity, and are free to use!

If your music file is an .MP3 file, you need a certain codec to be able to open files, which you can get here. It's called LAME for Audacity.

Once you have Audacity open, import the music file you wish to use. Along the bottom of the screen, you'll see a row of options that allow you to change how Audacity "sees" your music. Click the drop-down arrow and select the option of "Samples". This is one of the things you'll need to remember if you want to loop a track.

In your file, go to Tracks -> Add New -> Label Track. Pick your point along the track that you want to start the music loop (in the label track). Scroll all the way to the end to where you want your music loop to end. As you can see here, I've made a track with a section of music already highlighted, just to show you an example. Write down the numbers in the section below, where it shows you your song information, where it says "Selection Start" and "End".

Afterwards, go to Tracks -> Add Label at Selection, and it will give your label track a highlighted portion of your song. You will then type in the name "LOOP", or something generic. You now have your loopable section.

It's time here to make the finite edits to where you want the song exactly to loop. This I can't help you with, really. However, once you are done with that, you can hold Shift, and then click the green play button, to loop the song back infinitely. Or you can use Shift + Space. Either or.

Once you think you've gotten it down, go to File -> Export, and then Export your Project as an Ogg Vorbis. This part is entirely optional, but before you export, click on the Options Button and set the quality to maximum. It'll sound better during output.

After that, you'll see a dialogue box pop up. Clear all other irrelevant information, then press the "Add" button 3 times. I bet you can tell where this is going. Click on the left portion of the bar, and you'll see a text box pop up. You may have to click it twice. In that box, type in "LOOPSTART" (and yes, it must be capitalized). Go down to the second one and put in "LOOPEND". Then, go to the last one, and put it in "LOOPLENGTH".

But Arin, you may ask, what is this LOOPLENGTH thingamajigger? Well, it's real simple~ Remember how I said you needed to create the Label Track? In there, it will store the exact the point in which you created your loop. Go to the beginning, or look at what it says in "Selection Start", and copy that number to your LOOPSTART field, by clicking on the right-hand side. Do the same thing with LOOPEND, counting that as where your loop will stop. LOOPLENGTH is different, in which you have to take the two values of LOOPEND and LOOPSTART, and subtract them. That will give you LOOPLENGTH (and yes, this is necessary).

Once you're all done with that, hit Export! If you make a mistake, you can always re-open the project in Audacity again, and fine-tune it to your needs.
