Subject: can´t tune up mp3 loops when save blank is insertd

I have found great difficulty in tuning up mp3s loops with Sound Forge 6 ;

Looping range is selected precisely to loop continuously from the original sound file ;

I copy to the clipboard the looping range and paste in a new file (of course same sampling rate , bit depth ) ; until this point loop is equal to the selected range ;

As I save the mp3 file it occurs the insertion of a undesirable blank area at the beggining and end of timeline , what breaks up the loop ;

What am I doing wrong , is there a way to get rid of this annoying blank ??

Thank you very much for any light shed on this matter ;

You're not doing anything wrong. It's been discussed in here previously that the MP3 format requires a "space" at the beginning of the file.

Is there a reason why you're not saving to .wav?

The reason is the large size of wav files , which is about ten times of mp3.
I develop sites in Flash 5 and MX , even using pre loaders and external loading movies wavs are too heavy ;
I must assume that is impossible to use mp3 for loops that don´t begin or finish with silence ?
Thank you anyway for your reply
Cheers

Doesn't Flash 5 compress the audio automatically? I've never used it before, but I know that Adobe's Live Motion imports .wav or .aif, then compresses them into mp3 when you export. If not, isn't there a way to bring the mp3 in and "nudge" it to get rid of the space and not mess up any animation that is synchronized?

Again, I don't know how Flash 5 works. Just trying to be helpful.

Hi Jessariah ,
Yes , I can compress .wav files with flash by configuring the export settings of a sound file , indeed I can configure compression type (raw adpcm or mp3 ) bit rate and quality (fast medium and best ) , result is reasonably good ,so that´s the way I ´ve found to limit the size of the .swf movie files have .wav loops ;
However the work with .wavs keep limited because if I could have a 10 times less mp3 file the loops would not so boredom as I could employ larger tunes what would be much more interesting with no quality sacrifice and file increase ;
BEcause the "blank" I only employ mp3 when perfect loop depends on silence at the ends ;
I still have a doubt , is the blank problem a limitation of SOund Forge or a limitation of MP3 technology?? I´ve seen thousands of seamless mp3 loops in the web , most of them synchronizes sound and not silence , I just wonder how do those guys get it (because if it is an mp3 limitation no matter what the way sound has been generated , at the time of saving the file both ends blanks will be inserted spoiling the job )
Thank you very much for your answer.

A wav is a wav -- are you actually multi-tracking in flash? Is that why you want to reduce to mp3 before compression?
