Wasn't there a recording section?

Okay, that's not actually what this is about, but that's what I was thinking when I was looking for a place for this. Recently I recorded myself playing play directly into my PC with audacity (don't have an audio interface yet) and it sounded great (I have a line out on my amp) however, some reason it only comes out of one speaker. I didn't set it to save as mono or anything nor do I understand if that would actually make it do this but as of right now I have a composition that needs to come out of both sides. Anyone know how to do this? Just duplicate it to the other side and save it like that? Or even perhaps record a guitar part and set it as the other speaker? Love you guys.

I can't say anything with certainty, but it sounds to me like you set recording to stereo, but the signal was only coming in through one channel...which is normal.
When you record instruments, you do it in mono, but have the out signal in stereo.
So, if you say record a guitar and a bass, you record both in mono. Then, you play around with balance to send one more to the right or left or leave it dead center. For example, you lean the bass to the right speaker (it's mono, but it'll be louder in the right speaker than the left) and you lean the guitar to the left. What you get in the end is a stereo mix where the guitar is more prominent to the left and the bass to the right, thus creating the sense of space.

Think about it like this. When you play live, you don't have a bassist both left and right, just one standing in one place. Same goes for any musician. So, you have a bunch of mono signals (musicians) that create a single stereo output or mix (what the audiance hears).

So record in mono and set the output to stereo? Well if I already have it recorded what do I do? Open the same track twice in audacity and move on on the right and one on the left?

Ok, first off, I've never used audacity for more than recording a single track. So, I have no idea how the output stuff works, but it should be automatically set to stereo... I'm going to try something now...

Yes, the output is stereo by default. I can see and hear the L and R change volume as I pan the signal. Then, there's no need to change anything - just record in mono, or if you've already recorded...

Now, for your question question: In the top left corner, next to the name of the track there should be a small arrow pointing downward. Click it and choose the option "Split Stereo Track". Once that's done, you can click on either of the 2 new tracks' arrows and choose "Mono". Hey, presto! You have two mono tracks

Brilliant, thank you! Evidently there was no other side track, so with the split audio track I just copied and pasted it on to the other side. Thanks, mate!

Not sure exactly what you meant by copying, but glad it helped
Just be sure to set the tracks to "mono" in the drop down menu, otherwise you will always get a signal on a seperate channel, instead of 1 you can move however you wish.
