OK, I was converting all the tracks for my Postcard mix into MP3 and I thought what the hell I'll just mix it and have some cross fades and cut the songs tight together, trim bits off and so forth.

So I recorded the whole thing as one MP3 and then split it up using an audio spliter. Now the problem I have is when I burn the disc the programme I'm using (Windows Media Player) seems to be automatically inserting a 2 second gap between tracks which of course completely fucks the whole thing up since I have segues.

How can I split the audio on the one big MP3 and then burn it so it runs smooth like it does without the splices in it?

well i don't think that you can adjust that in WMP. That is another reason that it sucks. Also, I've never had any luck pulling this off seamlessly when every track is a discrete mp3; for some reason I've had to chop it up unti .wav files in order not to lose anything in the transitions.

for some reason these programs like to have the gaps in there. find one that will allow you to adjust the gap time. maybe a good one will allow you to have a gap time of .01 seconds.

In iTunes can't you make it 0 seconds?
Also, Toast allows you to adjust the time for each individual track... and 0 is an option with that, also.

yeah itunes can make it 0 seconds, but if, for example, you rip a continuous mix cd to mp3s and then burn an audio cd from those, you'll have perceptible gaps between the tracks even with a 0 second pause. I guess some sliver of audio gets lost in the compression.

Crack, it's not that audio gets lost, the mp3 format was just designed to insert padding at the beginning of each file to keep block sizes uniform. Most players see this and insert silence. Newer encoders, like LAME, write a header to each file that tells the program (so long as it can read the header) to skip over that silence.

Long story short, the mp3s konstantinl made have the silence built into them. I'd suggest decoding that one long file into a wav file, splitting that, working from the resulting parts and then burning the wavs directly to cd. That way you won't get the gaps.
