How to Download Dale Ralph Davis Sermons and Convert them to MP3 on Linux
By David Legg, 2007/2008. Back to Main Menu
The on-line sermons of Dale Ralph Davis are strongly recommended for everyone to listen to. You can get them here (Woodland PCA) or here (Aisquith) However, non-Windows users will notice, that in the case of the Woodland PCA web site files, they are not in a very friendly, portable or usable format. Windows users may be able to play them using some versions of the Windows media player, but I wouldn't know about that :)
A neat trick is to download them, then convert them into, say, MP3 format. There are lots of other possibilities, of course, but MP3 format will allow you to listen to sermons in bed on your Palm, Nokia N810 (smug grin :), in your lounge on your DVD player, or in the bath on your iPod or MP3 player. I'm not young enuf to know about iPods either :)
Here are some instructions that work on Fedora Core 5 (FC5, FC6, FC7) and similar. Please email me if it works for you on other operating systems at dwlegg (at) gmail (dot) com, or to submit other instructions or suggestions. See the bottom of this page for a contribution from Tim Heaney.
1. Go to here and download the mplayer packages and install them. You can also use yum to install things from the livna site.
2. Go to here and download, then install, the BladeEnc program.
3. Use mplayer to convert your .wma file into a normal PCM audio file, i.e. like a CD track:
mplayer -vo null -vc dummy -af resample=44100 -ao pcm:waveheader "davis_sermon.wma"
4. Use BladeEnc to convert the resulting .wav file into MP3 format:
cat audiodump.wav | bladeenc -mono -br 64 STDIN "davis_sermon.64kHz.mp3" rm audiodump.wav
Note that this last step converts a 50MB sermon into a 25MB sermon at quite a pleasant sampling rate, 64kHz, but in mono - thus saving lots of disk space or memory card space.
Some particularly well-worth downloading stuff:
A.M. Sermon - Isaiah 53:10-12, Hebrews 2:10
"Hallelujah! What a Servant!"
1/7/2007 P.M. Sermon - 2 Samuel 6
"A Worshipper before God's Holiness or: Holy, Holy, Holy
See also the Bible study series on Genesis which starts July 2007.

Here is the kind contribution from Tim Heaney:
Hi I just stumpled upon http://davidlegg.org.uk/dale_ralph_davis_linux_howto.html and I thought I'd add that LAME http://lame.sourceforge.net/ is another popular MP3 encoder. Before downloading and installing BladeEnc, folks might want to check that they don't already have lame. If so, to convert to 64k monophonic MP3, they could run:
lame -b 64 -m m audiodump.wav -o davis_sermon.64kHz.mp3
However, you don't really need to download the WMA to a file; mplayer is happy to take a URL as input. For example, to download and convert the latest sermon, I could run
mplayer -quiet -vo null -vc dummy -af resample=44100 -ao
pcm:waveheader http://www.woodlandpca.com/media/8-5-2007%20AM.wma lame -b 64 -m m audiodump.wav -o 8-5-2007\ AM.mp3
You could, of course, do the same thing with bladeenc. Tim
