Have you tried tweaking it with Audacity?
It's a fully functional, all the bells/whistles
multi-track, multi-format, open source file
mixer and there's nothing to worry about.
No adware, no spyware, no malware, it's
just a great little program and I love it.

I downloaded that and tried to make the track smaller, but in the end it either actually make the track bigger, or make it sound like it was being played through an AM radio. I'm not to good when it comes to using new software XD. I knida need to be walked trough it. I looked up tutorials on YouTube and tried following them and it still didn't work.
