How do I mix MP3 audio tracks? | Sound Editor, MP3 Mixer

Mixing of different audio tracks is not unusual. In fact, it is pretty usual. All modern music is done separately for each instrument and voice, and only later they are mixed into a single piece. Audio books are read with some musical background that helps to deepen emotional experience. Sometimes it is just fun to put unrelated things together to make people laugh, or to explore new dimensions of ordinary things.

Well, isn't that a bit philosophic? We want to something real, don't we?

Let's consider a simple example of mixing with help of Acoustica MP3 Audio Mixer - an easy-to-use tool with professional capabilities.
