In part 4 of my Linux soft synth tutorial, I look at Xsynth-DSSI's amplifier section, and particularly the "envelope", which defines how the volume of your sound changes over time. By tweaking the envelope, you can make your sounds fade in and out softly, hit hard and then slowly fade like a piano, or come on strong and then disappear just as quickly, like a xylophone.

High-res Ogg Theora version is [here](http://electronaut.linuxgamers.net/~lsd/music/synthtute/part04%5Famp%5Fand%5Fenvelopes.ogv?ref=wootangent.net), or watch the Youtube version after the jump!
