This script fades the volume of your Linux box up or down over a set period of time.

Aumix script for volume fades


Just type: fade.sh 60 0 to fade down to zero, over 60 seconds. It begins at the current volume level. I use it for gradually fading out my music in the evening, and fading it in again come morning. Both are triggered from cron.

It doesn't work accurately over very short time periods, but I don't need it. The code's under GPL though, so if that's your itch... scratch it!
