I was looking for a software to play the azan at the proper prayer times and found this link:
http://www.islamicfinder.org/athanDownload.php
Its great for people who either live in non-muslim coutries or far from a mosque and cannot hear the azan being recited.
There is a free version as well one that can be purchased. The software automatically calculates the Azan time according to where you live. I checked the times in the software with the times given in our "Muslim Calendars" here and there's just a 1 - 2 minutes difference in the time. You have to select the your region, time zone, jurisdiction method and the correct calculation method according to where you live and voila! its done!
