That’s what I was after ![]()
If you have not already installed LAME and FFMpeg, follow these instructions to do so:

LAME is required for exporting MP3 files.
FFMpeg will hopefully allow you import the audio portion of the VOB file.
You should now be set up to do the job.
- Reading directly from a DVD can be temperamental, so copy the VOB file to your computer hard drive.
- Open Audacity and from the File menu select “Import”.
- Navigate to where you saved the VOB file, select it and click OK to import it.
If it was a long recording it may take a while to import, but hopefully you will end up with an audio track with a wiggly blue waveform. - Optional but often recommended for Podcasts: From the “Tracks” menu select “Stereo Track to Mono”. (this option will be grayed out if the track is already mono)
- From the Effect menu, select “Normalize” and enter the following settings:
- Remove DC offset [Selected/Enabled]
- Normalize maximum amplitude [-2.0] dB
- Normalize stereo channels independently [Not selected/disabled]
- You now need to find the sermon. With a bit of practice you may be able to do this quite accurately by eye. The spacebar can be used to start and stop playback. Click on the waveform at the point that you want to start playing.
- You can zoom in and out to locate positions more accurately. Audacity Manual
- You now need to “Select” each part that you don’t want, and delete it. See here for how to make a selection: Audacity Manual
- When some audio is selected, delete it by pressing the DEL key.
- When you have finished editing the track and have just the sermon that you want, it is time to “Export” it (create a new audio file).
- If you want a backup for possible editing in the future, export as a WAV file. This will be a “best quality” backup copy.
- For your podcast, export as an MP3 file.
- See here for a detailed description of exporting: Audacity Manual
There are many other things that can be done to enhance the quality of the podcast, such as reducing background hum and hiss, optimise the MP3 compression settings, and so on, but hopefully this will get you started and you can become an expert later ![]()
