The Volcano Kit Beep Maker

Creates various beeps, sirens, and
noises built to your specifications:

Frequency: The base pitch, in hz.
Length: The time, in seconds.
Wave Shape: Controls the tone.
Envelope: Controls fade in/out.
Delay: Creates an echo.
Warble: Modulates the volume.
Modul: Modulates the tone.

The sounds are generated by a php
script and saved as a .wav file. I don’t
know why I made this.
