deroad a PS3HaX member, developer and MAJOR contributor to both PS3 Dev Wiki and Vita Dev Wiki, has released a snazzy little home brew app, which he calls Buzzer Player, here is a quote from the thread and readme:

i wrote it for naruse and euss since we was talking on the irc about the buzzer.

maybe someone will find it funny xD

this is a simple player
it reads two var (var1 and Var2) from a file.

the file must be called buzzer.txt and placed in the main folder of a USB an example:
on Windows:
My USB is j so, i will put this file here: j:/buzzer.txt

on OSX: My USB is 8GB so,
i will put this file here: /Volumes/8GB/buzzer.txt

on LINUX: My USB is 8GB so,
i will put this file here: /media/8GB/buzzer.txt

======Beeps=======
Var1 Var2 DESCRIPTION
4 6 Makes a short single beep
10 438 Makes a double beep
7 54 End
10 4095 Makes a continuous beep
