My 5p's worth: I use a little program called CDWav to chop the 'big' .wav file (e.g. one side of an LP that you've previously recorded onto your disk drive) into smaller .wavs. I can't remember where I got it from now (I think it was shareware but I've had it for so long I can't remember), but I've used it for years, and I like it because it's simple to use and does the job. (I don't like relying on software to find the gaps for me, as it's not IME 100% reliable in this respect (especially for a live recording without gaps).)

In CDWav you just open the 'big' .wav, and it displays the waveform at the top, for the whole file, and highlights a smaller section of the file below in more detail. You can click anywhere on the waveform at the top to highlight a different part of the file on the screen below. You can play the file and listen to where you are as you do it, to make sure you get the split in exactly the right place.

For studio albums you can easily see where the gaps are, and you can click at the appropriate place and then click on a button to insert a marker where you want a 'split' to be. For files without gaps (e.g. a live recording), you can click roughly where you think the split should be and then click again until you find the best place to split the tracks. It instantly starts playing from wherever you click, as you do it, which makes it very quick and easy to 'tell where you are' in the file. It's very easy and intuitive to use (btw I have no commercial interest in it, I'm just a satisfied user).

The display of the waveform at the top uses different colours to show the different tracks, as you split them. When you've done, you just click on save, to save the original file as lots of smaller .wavs. Then use your favourite burning software to burn to a CD (remembering to cancel the 2-sec gaps if the burning software defaults to that).

Although you can get software that does everything for you, I prefer to do it this way, partly from habit, partly because I have more control over the process, and because I know it works for me.
