Hi, I wanted to convert some MP3 tunes into OGG to save space; however, when I use audacity, it seems to make the file larger. I tried to look in preference, but I have no background in sound technology at all and I am not sure what I am doing. Can someone walk me through this and help be balance quality with space?
Ha! I did a test using Super and the same thing happens to me. The filesize jumped from 6 megs to 9.

Hm? I don't see that option anywhere. Even so ... I don't really know what is the most well-balanced setting. :(
After you click export and get the save file dialog, click the Options under Cancel so you can select a bitrate. Go low, listen to the result, and if it sounds bad export again and increase the bitrate. The best bitrate is based on the music, how picky you are, and the quality of your sound system.

I generally go for 64kbps and work around that. Don't touch the channels or sampling frequency.

What program are you using?

Audacity is a great, free tool for working with oggs.

EDIT: Ugh. I just now saw that you already stated using Audacity. Wish I could delete posts!

Oh I see why I didn't see this - I had a much older version of Audacity, ha.

So I tried to lower it ... but nothing really happened.
Make sure when you're exporting you're exporting as OGG (pull down menu under the file name). Also the OGG options is a quality bar, not bitrate. oops
I read a very cool tip in another thread from way back. I'll just put it out there in case you never heard it.

Speed up your song in Audacity for a shorter/smaller file, then in RPGmaker turn the tempo down so it plays at regular speed.

I thought this was just genius. I havn't tried it yet but if it works good I'll be doing it for sure.

No. I use to do that, but it loses some of the quality. I think OGG is the best route to go.

This is what I've been getting and this is what hasn't been working for me much ...



I tried setting it lower to 2, etc. but it didn't help much.

Identical settings and files to the screenshot you pasted above yields me a size change of 829KB to 613KB. It's small, but the size reduction is definitely there. Sound quality doesn't sound bad either, at least for me.

And yes, I agree that speeding up the tempo will adversely affect the sound quality. We used to do it with RM2K when we could only use WAV files and it was less than ideal of a solution.
WAV tracks for music files are horrible. It makes the little 2D game the size of like Oblivion just for a WAV file version of something. I won't name the game but there's a game on here with a huge download. It's RPG Maker 2003. Not only did they use WAV files but the files also sound horrible- defeating the purpose of having them lossless. All it does it make the download HUGE.

Now different formats will just compress differently. Perhaps for some particular inputs of data, MP3 can beat OGG in size. I personally use OGGs for their quality and freedom-ish-ness.

And remember for lossless data compression (like file zipping, etc.), there exist such data inputs that would actually make the resulting file bigger.
