Exporting to MP3 with Lame taking 14+ hours

Hi everyone -

First of all, I am a totally new user to Audacity. I've been using it to edit podcasts and have pretty much figured out the editing process, however, I am a total noob when it comes to the technical side of things, so please be gentle with me and dumb things down if you can. ;)

I'm using Windows 8, Audacity 2.1.1, and my computer kinda sucks. It constantly is telling me I am low on memory - I've been meaning to fix this, but, money. My computer has a 500gb hard drive in the keyboard, which I have been using for Audacity. All the temp files and exports save to this hard drive, and Audacity itself is on this hard drive. When I'm editing on Audacity, I close all other programs, because of the memory issue. And I'm using LAME for exporting to MP3.

I haven't had any problems until today. Usually, it takes a few minutes to export a file that is about an hour long, with all the settings at default - 44100 Hz, etc. Basically, I don't change anything when I export, and it works fine. Until today. Today, it's telling me that it's going to take 14+ hours to export.

I have searched for this problem on Google, and in the forum, and I'm either not getting any pertinent info because the posts were too old, or there's a bunch of technical jargon that I just don't understand. So, if someone could take pity on me and humour me and dumb this all down for me, that would be great. I would appreciate it SO much. This podcast episode has to be out on Thursday...

Thanks in advance!!!

Have you tried restarting your computer?

I wonder if there's something running in the background using all the memory?

Try running the Task Manager (Ctrl-Alt-Delete in Win7, but I'm not sure about Win8). That can give you CPU and memory usage, and it can give you hints about what applications are hogging your resources.

I haven't made any hour long files recently, but from what I remember I'd say "several" minutes.

My guess is, if you wait 14 hours you're going to get an error/failure at the end. :(

If your computer has a utility to check the CPU temperature, check that. I've had a CPU fan fail and the computer slows to a crawl to prevent the CPU from burning-up.

Hi there - thanks for your response. I attached a screenshot of my task manager - looks like 20-30% of my CPU is being used with Chrome, Audacity, and the MP3 player open...I don't know if that's a lot, but it doesn't seem like it.

I'm not sure how to check CPU temperature, but I will try.

Is there some trick when exporting to make it a smaller file? I know I'd be compromising quality, but if it's going to less time than 14 hours...

Sure have. That was the first thing I tried :(

How much physical RAM memory does your computer have?

2.00 GB (1.89 useable) is what it says. Did I mention my computer sucks? ;)

Do other files take hours that before took minutes?

See if another mp3 encoder has the same problem.

Check how much RAM your machine is reading. You might have had some go down.

Well, just last week, I edited a sound file that was 1.5 hours and it exported in under 10 minutes. The one I'm trying to do today has 3 audio tracks in it, but I've done that before and it hasn't taken this long. I'm stumped.

What other encoders are out there? I tried the FFmpeg one but I couldn't figure out how to actually use it. I suspect it might have something to do with the encoder.
