Digitizing Sermons.
Mar 8th, 2005 by Lyle Melick
I host the sermons for our church. The sermon webpage is actually here since I have a lot of disk space available on my home server. I thought it might be helpful to talk about the process I use to generate the files.
I rip the sermons from tape. I could also do this live, but that’s another story. I use Microsoft’s analog recorder from the Plus Pack for Digital Media. This allows me to remove some background noise (on a sufficiently powerful box), and I’m left with a WMA file. Since I have Windows Media 10.0 loaded, and the WMA file won’t load into the Acoustica product, so I use the Advanced Audio Workshop from Litex to convert the WMA to an MP3. I then use Acoustica’s MP3 mixer to convert the file to RealAudio. I’m also going to use it to add bumpers at the beginning and end of the message, and I’ll need to update the MP3. I then use the Advanced Audio Workshop from Litex to convert the MP3 to Ogg Vorbis and a smaller WMA file. So now I have an realaudio file (usually about 5MB), a WMA file (about 10MB), an Ogg Vorbis (about 20MB) and my MP3 file (about 10MB). My pastor normally speaks for about 45minutes. YMMV.
WMA
I use 32kbs, 22050 sampling rate, stereo and a constant bit rate for settings in the Advanced Audio Workshop.
MP3
I use the preset “AM Quality” - MPEG 2, Layer 3, 32kbs, mono and the LAME MP3 Encoder (version 1.28, engine 3.92) in Acoustica.
RealAudio
I use 28kbs Modem, voice only, audio only, single rate for webservers (16kbps voice) in Acoustica.
Ogg Vorbis
So far I’m using 44.1kHz sampling, mono & quality 5 in the Advanced Audio Workshop
