I'm just now getting around to digitizing my Father's Day sermon "Heart of the Matter". It's online here now. Even with a dial-up connection you should be able to stream it.
HOW TO COPY FROM TAPE TO CD VIA YOUR COMPUTER
Since the sermon did not get recorded digitally, I got the tape and did it myself. I used my little portable tape player (thus the quality is not super great) and ran a cable from the headphone jack into my laptop's mic jack. Both ends of the cable had a 2.5mm jack on it. You can find one of these at Radio Shack. I used the free program Audacity (http://audacity.sourceforge.net) to do the actual recording.
To create a streaming MP3 file, open up Notepad and type in the address where the actual MP3 file is. For example, the MP3 file I am streaming here is HeartOfTheMatter.mp3 It is on our church server. So I created a plain text file and named it HeartOfTheMatter.m3u In this file is just one line of text...http://www.tnlf.org/audio/HeartOfTheMatter.mp3 When you click on the link above to hear my sermon (if you do that), the file links to http://www.tnlf.org/audio/HeartOfTheMatter.m3u and that file will automatically begin streaming the MP3 file.
