Hello,

I'm having a problem and it's frustating the heck out of me.

I got a paying gig to provide some loops for website. They need two 30 second or so mp3 files of my music that loop seamlessly.

No problem...or so I thought.

For some reason, my wave files loop perfectly. When I encode the MP3, the encoder inserts a little bit of silence at the beginning and end of the file, and they will not loop without gapping.

I don't have extra time selected on either side of the loop. The wav files are cropped perfectly. I can't figure it out.

I have tried encoding the wav files from SONAR 3 and from Mediaworks with the same results.

Does anyone have any ideas on how to do this? Or know of any programs that will let you edit MP3 files without having to re-encode them, because I could just trim those files.

Thanks in advance for your help!

As far as I remember, its impossible to loop mp3s seemlessly, unless you do some live crossfading.

The way mp3 encoding works means that there is always a gap either at the beginning or end, I'm not sure why, but a quick search on google will probably enlighten you.

Yeah. mp3 encodes in blocks, so the sample length is never gonna be accurate. You'd be better off .rar-ing your wavs, making them mono, whatever..

if they use some flash player, you can offset lopping point for loaded mp3 file with as instruction (search actionscript.org or similar, you might even look more *pro* if you deliver more complete solution). this won't make a perfect loop as it was in wave, but gaps will be less distracting. the key to minimizing this is making a drum-based break at the end of loop, so gap-effect wil be further minimized (plus you CAN this way *experimentaly* cut silence at the end of your *.wav and hear how it encodes IF real-looping mp3 IS required). anyhow, use your brains. no mp3-trim will help with this though, because you have additional data besides sound info at beginning and end of your mp3.
