COUB.COM - Entry 9 - Trimming Audio

When you explore Coub.com you wil find some with a small gap of silence after the coub starts. The video will have started already but the audio begins a fraction of a second later. That is just sloppy. In fact, there are serious users out there that like to "fix" coubs that have this type of flaw. Do not get confused with the good kind of flaws. That is another story. This story right here is about that gap of silence. I'm going to try to explain how to trim the audio so there is no silence before and after, unless you want it.
First go here http://www.audacityteam.org/download/ and download Audacity.
Once it's installed and open, import an audio file that has a silent part at the beginning.
After the file is loaded, locate the magnifying glass at the top toward the left and click it a few times.

Now you should be able to see where the soundwave begins.
You are going to click to the left of where the line becomes jagged. Hold the click and drag to the left to 0.00 time.

Then press delete.

You can do it to the end of the soundwave as well. Click the zoom out (next to the zoom in) until you see the end of the soundwave. Click on the line after the jagged line smooths out. Zoom in and click and drag to the end. Then delete the selected part.
Next you will want to export the audio and save it. Click File > Export Audio. You have to rename it.
Now you can make your coubs have sound that starts straight away.
