Right, you know if you have a mixed cd, and when you rip it to seperate mp3 tracks, why do you allways get that annoying bit of silence at the end and beggining of each track. It's only tiny, but is big enough to be heard.

It really annoys me, coz I have to waste my time edditing all the tracks and saving them as wav files before I can burn them to cd.

Does anyone know why when you encode an mp3 it does this?

- so put simply ...


WHAT ARE MP3 GAPS?
These are the short silence gaps at the beginning or end of music tracks that result from ENCODING an audio track into mp3 format. They are NOT the gaps on a CD between audio tracks put there by the CD manufacturer. mp3 gaps were NOT there originally and are merely an artifact of the encoding process. These sections of silence are needed by the mp3 encoder and decoder to ensure that there are an equal number of "samples" in each part or "frame" of the mp3 file. The mp3 encoder/decoder needs this so that it can perform its frequency analysis properly in order to compress and later play back the audio signal.

Almost every audio track encoded to mp3 will have these small gaps added to either the beginning and/or end of the final mp3 file. Generally they are less than a second (often 0.1-0.2 seconds long) and may not noticeable at all. But they clearly can be heard when playing tracks sequentially where no break originally occured in the sound or playing between tracks on the CD.

there we go ... clear as mud ;) :thumbsup:

Does that mean everyone that uploads mixes onto this site always has annoying gaps between each mix, or do they generally rip as a single track to avoid this? After all it would spoil the mixes!!
