Compressing Files for your church website
Audio files should be in MP3 format before they are uploaded to the website. There are various software that will convert sound files to MP3, but the best way is to originally record the service in MP3 format.
Preparing audio for the web
Once you have your recording, you need to get it onto your computer, and prepare a file which is suitable for use on the Internet. This will be an 'MP3' file, which is compressed to make the file smaller, whilst retaining most of the sound quality. For speech recording, heavy compression should be used to make a relatively long recording (such as a sermon) into a small enough file to download over the Internet.
One option for compressing your files is to use Switch.
For recording and compressing audio, we recommend the free 'Audacity' audio editor available from http://audacity.sourceforge.net/download/windows .
Transferring recordings to your PC
Exactly how you do this depends on your recording device. If you use a digital audio recorder like the Edirol, you can plug it's cable in, or put the memory card in your computer's card reader, and copy the mp3 or wav file to the computer. If you have a mini disc with PC interface, use the software it came with to transfer the recording. If there's no way to transfer your recording digitally, you'll need to use an analog audio cable (looks like a small headphone plug on each end) and audacity to re-record the material into the computer. Connect the line output of your device to the line input of your computer's sound card. Use your computer's volume control settings to increase the volume, whilst making sure the level meters in Audacity aren't overloaded. Press record in Audacity, and play on your device. (Stop and play it back after a few seconds first, just to check it's working, then start again and go through the whole sermon.)
Compressing the file in Audacity
Once your recording is made in audacity, (if you transferred your recording digitally, just open it up in Audacity) you can trim off any excess at the beginning and end of the recording, then save the compressed file. To erase part of the MP3, highlight the part of the file you wish to delete and then go to EDIT > DELETE . (Make sure you have a backup of your sound file first)
Congratulations, your file is ready to upload to your website!
