'''AudioAlarm''' is a program that asks the user to enter a certain number, representing a number of seconds. After the user enters the number, the program will ask the user to enter the name of an MP3 audio file (without the .mp3 file extension). The program will then display a (usually blank) page. After the time (indicated by the number) is up, a sound (indicated by the MP3 file) will go off. Useful for timers and alarm clocks. The app must be installed in its own folder, preferrably with a name like ''AudioAlarm''. To install a sound on the app, just copy the MP3 to the app folder you set up. Then, when the app asks you for the filename, you just type in the name without an extension.
