<div class="IPBDescription">searched for hours with no luck =(</div> will provide short and long versions of this question (if you dont understand the short, read the long):
SHORT VERSION:
Goldwave inserts gaps in the music of MP3's (at beginning and end of each song) how do i get these gaps to go away?
(cutting them away in goldwave and resaving dosent work because goldwave just puts them right back in)
LONG VERSION:
I have a bunch of WAV loops that loop seemlessly (you cant tell where it begins and where it ends, there is no gap in the music)
I used goldwave to convert them to MP3's but they started "hiccuping", when i looked closer, i saw that the MP3 files that goldwave made had gaps in the beginning and end of every song...
So i went into goldwave and i "cut" the gaps at the beginning and at the end of the songs and told goldwave to play them in a loop, and whalla! they loop correctly!!! It was the gaps that goldwave made that was the problem....
But heres the catch.
When i attempt to save the files as their respective MP3's Goldwave inserts the gaps again, effectively cancelling out what i just did!!!

Cool Edit Pro (now Adobe Audition) and Sonar 4...

easiest way I have found to manually do this - listen up kids..this is not tricky but it aint simple either.. (this suggestion assumes that it starts and ends with full sound...if it doesn't - chop a bit off the start and end so that we have full sound)
1. Go to the end of the sample
2. Select 1 sec of it and fade it out to zero.
3. Go to the beginning, select 1 sec and fade in
4. Cut that selection from the beginning and mix paste it over the end.
Simple. But you have to do it right or it'll stuff up - but essentially - that gives you a perfect loop.
Purple Monkey Dishwashers.
The reason you can have seamless WAV loops is a feature of the WAV format called "Cue Points" (also known as loop points). You can set those points in tools like Cool Edit and save them into the file. Those points do not have to be at the very beginning or end of the sound (especially when using those sound to create music most the time you need them somewhere in the middle). If you use a looped WAV in HL/NS, those cue points will be used (if the file doesn't contain any cue points it will loop from the beginning to the end).
The MP3 format does NOT have cue points, therefore it's not possible to create loops inside the sound. Also the entity NS uses to play MP3 files will create a small gap before playing the MP3 from the beginning again. There is NOTHING you can do about it, sorry. No matter what you do with your MP3 file, it won't play as seamless loop in NS. That's the reason all seamless ambient sounds are WAV files.
