Oh, this is going to be fun. Here' how you get rid of the blank space at the beginning and end of the tracks that you don't want.
AND LOOK AT THIS. EVEN IF YOU'RE USING MUSICMATCH OR SOME OTHER EDITOR, YOU CAN USE SOUND RECORDER TO GET RID OF TALKING AT LIVE PERFORMANCES at the beginning and end of your tracks HERE TOO.
Here's how you do it.(First, either record your track into sound recorder, or open a track or tracks you've recorded elsewhere in Sound Recorder).
Then, Click the play button and then grab the handle of the slider while it's moving. Play with it a bit and you find that you can adjust the position pretty easily till you get it right at the start or end of your music. (You'll get used to ANTICIPATING the sound breaks just before you want to stop pretty easily.) When you're there, click the stop button. This is really easy to do after you play with it a few times to get the hang of it.
You may have to futz with the slider a bit till you get used to it. But, you'll find pretty quickly that if you look for the long black space at the beginning or end of your track that it's not hard to find. And the only time it's at all hard is when you're removing someone's dialog that comes right up to the music.
You'll be able to do it. It just takes some practice to get used to it. But, it's really worth the effort to get rid of the talking so you don't have to listen to it every time you want to hear the track. You see, the CD is really much better than the record.
