I want to trim a sound and then let it loop in a slideshow. The sound -- a roaring crowd at a soccer game-- should loop as a slideshow plays. As the movie repeats the sound should continue to play. It doesn't have to be in sync.
This works if I use Streaming, but there's a gap at the beginning of the movie as if the sound was being loaded over and over again.
I've been advised not to use Streaming, but if I don't, the sound is reproduced in its entirety-- there is no trimming.
This might sound complex but it's really straight forward. Go here
Download the program for your appropriate OS.
Open the program once installed and drag your sound file into it. It will open and show the wave pattern drawn out. Scroll through the sound until you get to the place where you want to trim it. Simply click to select and then drag on the wav pattern to the end and then press delete. This should trim up your sound. You can then save it in a few formats. For MP3 you'll need to download the lame mp3 encoder. When you choose to export to mp3, audacity will ask you to point to the mp3 encoder dll. Just browse and select it and you can export your new trimmed sound.
Hope that helps.
Thank you VERY much-- that solved the problem perfectly. Instead of downloading the lame encoder I found a free utility called Audacity which was easier, for me on a Mac, to understand.
