I've got an MP3 file, which I'd like to burn to a CD, to create an audio CD.
Unfortunately, it's a tiny bit too big (722MB, disc size 702MB) to fit the CD.
Is there any way (preferably using a program on my computer), in which I can reduce the file size?

what will you be using to listen to the Audio CD?
Will it be a PC or a cd/dvd player?
Audio CD's don't use mp3's the convert it to LPCM (like a WAV file) so you'll get 74 - 80 mins per CD.
How long is the amp3 audio file? you might need to split it over a couple of CD's
If you know your player can play MP3's then you can encode the audio to a lower bit-rate
use a program like audacity to re-encode the mp3 that will reduce the size, have a play around and see if you can get a file size you can work with.

OK you might need to check if the cd-player can read MP3 files.
burn any mp3 file to a disk and see if the car can play it. If not then you'll have to creatre an Audio CD instead.
I'm sure Windows Media player can handle that. Most CD-Burning software will be able to convert a MP3 into an CD-audio disk with a couple of clicks. But you'll be limited to 80 mins per CD.Laters

That's what I'm doing.
I already created one Audio CD, which plays in the car, but this file is a touch too big.
However, I think I may have found a way.
I've just discovered that, the Clip Converter website has an option to adjust the bit rate of MP3 files it creates, so I've reduced the bit rate setting a bit, and have just finished downloading the MP3 file.
EDIT: Changing the bit rate makes no difference to the size of the file on the Audio CD.0 -
Was just about to suggest MP3 moulder , but it seems your sorted ...

You can ONLY fit 80 minutes of audio onto an audio CD.
How long is the listening time if the mp3 track?Laters

You *might* just about be able to use overburning to fit that on to an 80min CD-R.

Apparently, 90 minute and 99 minute CDs exist now. Maybe that would be another alternative.
Or use software like MPtrim (or Audacity or whatever) to cut the track down by a few minutes.

MPtrim edits the file directly, without transcoding it into a waveform and then back to MP3 (as many tools do), so it won't degrade audio quality.0 -
It will be the Mp3 play time which is the problem so you will need to find a solution to that. Either overburning to a larger capacity CD, cut off an audio track, cut off part of the track and fade the audio out, reduce the gaps might save a little space but not much. 2+ minutes is quite a lot to reduce it by without leaving off an audio track.0

I would be tempted to just drop the least-favoured track from the listing.
What car is it (and age) and what model radio/CD player? Have you checked that it WON'T play MP3s direct from CD? (Most will do ... even my wife's 57 plate Honda Jazz will play MP3s from CD as I recall).0
