I am not sure if this is new, or I just noticed it, but when saving as MP3, Sound Forge seems to add time to the front and back of my file. For example, if I trim a file to some length X, or stretch (reduce) the time to X, when I save as an MP3 file, the time is extended by some amount Y. Seems to add time at both the front and back of file. This does not seem to happen if I save as WAV. I am working with very short files (less than 1 sec) and want them as short as possible. Is this by design, or is there some setting I have wrong?
