What I have is a hour or more speaking mp3 audio file and I would like to make a regular CD from it. I tryed it errors in when trying to burn it. any suggestions

A normal cd in today's standard are 80 minutes 700mb. When the program converts from mp3 to cd audio the file size gets larger! It won't fit on one cd. You need to split the mp3 file or convert it to a wav file to see how big it actually is, then split it.

Well, the original post says that it's about an hour long.  So, that should fit onto a CD, unless, as you say, it's over 70 minutes, in which case, it will need to be split, but that may not be the whole problem.

The question then becomes, how was it originally recorded?  What was the original sample rate?  How many bits were the samples?  Stereo or mono?  What is the bit-rate of the .MP3 file?  If you play the file using something like WinAmp, it should tell you what the bit rate is, and if you see the bit-rate changing, that means that it's Variable Bit Rate encoded.  It will also tell you what the sample rate is.  You can also try right-clicking on the file in Windows Explorer, choose properties, and if there is an "Advanced" tab, click that, and that may show you all sorts of properties about the file.

If it is only 4 bit samples, then you'll need to use an audio editor like GoldWave to convert it to 8-bit samples, and it also needs to be a sample rate of at least 11.025Khz.

Let us know how you make out.
