After writing a few alarms using winsound.Beep, desire to expand into other sound possibilities led to the writing of this program using winsound.PlaySound. The sounds are stored in a custom format (some experimentation in archiving files). This is committed for archival to be run under Python 2.5 or later versions.

If you want ready-made sounds, you can download and use the sounds.bin file.
Where can I find the msvcrt module? I am getting the following error message: ImportError: No module named msvcrt
You have to be on Windows to use the
msvcrtmodule. If you know a module for Linux that can play WAV files, you might be able to use it as a replacement in thealarmfunction.
