Hey, I need to make a loop in mp3 format. The file I make in .wav is perfectly timed and fits the loop.When I export this file to an mp3 format, soundforge put a small piece of silence in front of my loop, not much but enough to make it un-loopable. How is this possible, is it the mp3 format or a preference? plz help, jazz |

Oh man, what happened when you did a search in this forum for (loops AND mp3)? I'm sure you searched because any reasonable person would before posting, hopefully avoiding the embarrassment of posting the same question asked gazillion before him has, surpassed possibly only by "How do I remove vocals from a stereo mix?". Did you go blind and you couldn't read the search results or the posts? If that's the case then I'm very sorry and I'll understand you can't see this post either. I can only hope that you will have someone that can read follow up on your post and tell you "THAT'S THE NATURE OF MP3, YOU CAN NOT SAVE LOOPS AS MP3s, SAVE THEM AS *.WAV OR *.PCA". MJ P.S. Learn how to search for your benefit and those around you. P.S.S. The Dolphins just lost to the Texans so I have NO patience which I'm sure means nothing the majority out there. |

As MJ indicated, you should leave your loop in WAV format. MP3 files add extra silence at the beginning and end of the file. Why do you think you need to use MP3? |

I've seen this question asked and answered a few times and nearly everyone says it is the nature of mp3, but as far as I know noone has really described just what it is about the mp3 format that causes it, so...(very simplistically) An mp3 codec will divide the audio into fixed size frames, each with a header that describes the frame. Unless your audio happens to fit exactly into an integral number of frames, there will be space left over at the end of the last frame. This space is usually filled with silence (digital zero), although some older, lousy codecs would just leave whatever bits were there when the memory was allocated. |

Actually I need this loop in mp3 format because of the small size of the file. I created a Flashplayer to put online on a website. I wanted the soundfile's to be loops. I can use wav also but quality and size is a problem. Still thanks for all ya supports ;-) Grz, jasper |

Ahhh, i was guessing it was a Flash related project. Keep your loop in .wav format. When your Flash authoring program creates the .swf output file it will encode to MP3 for you, and do so in such a way that the gaps are avoided. You gain nothing by encoding to MP3 first. In fact, you actually lose because the authoring program is going to re-encode anything you give it which means your loop will be compressed twice. Since each encode results in a degredation of the sound you want to avoid doing it multiple times. |

In addition to what Chienworks said, you can keep file size down by using a smaller resolution and sample rate and keeping the files in mono rather than stereo. 8-bit/11 kHz, mono audio usually works well in a Flash presentation. (Use the Process>Bit-Depth Converter and Process>Resample commands. The general rule of thumb is to resample first, convert bit-depth afterward.)
