[Notification Sound] Thunderbolt
This is a fairly simple little thing, but I noticed there were several people who wanted to use the Thunderbolt bootup sound (FinalThunder.mp3) as a notification sound. I didn't like a few things about it, so I modified it to improve its use in this way. Because lower frequencies are less audible with the Thunderbolt speakers, or any phone for that matter, It's been modified with a boost to upper frequencies. It has been reduced in length to ~2 seconds using the most appropriate section I could find. Finally, I've increased the volume and applied a limiter in order to maximize pocket-penetration.
You can install it into /sdcard/media/notifications. /system/media/notifications or /system/media/audio/notifications can be used if you have root.
Feel free to request modifications or include in any ROMs you make.
Enjoy, and let me know if you like it
