2.1 Changing an encoding profile via Sound Juicer
2.2 Changing an encoding profile via gconftool
Introduction
Sound Juicer can encode to MP3. From Ubuntu 7.04 onward even the appropriate encoding profiles are created for you, but sadly the shipped MP3 encoding profile is not ideal. Lame, the MP3 encoder, has a number of encoding presets which are well tested and tweaked to give the best result possible at the bit rates they support. So first, go and read this... ...to determine what encoding preset you'll favour. I have found medium to be more than adequate for iPod and desktop playback. To see what the lame options are available via GStreamer and what they mean, run the following...gst-inspect-0.10 lame
Changing the MP3 Encoding Profile
You can either change the Sound Juicer encoding by profile by starting Sound Juicer and going to Edit -> Preferences -> Edit Profiles... or by running 'gconftool' The examples below show how to setup Sound Juicer to use the Lame's medium preset, if you want to use standard, extreme or insane then just change 'preset=1006' to the relevant setting.Changing an encoding profile via Sound Juicer
- Edit -> Preferences -> Edit Profiles...
- Select CD Quality, MP3
- Click Edit
- Change Gstreamer Pipeline to...
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc preset=1006 ! id3v2mux
Changing an encoding profile via gconftool
Just run the following from the shell as your own user account, not root.gconftool-2 --type string --set /system/gstreamer/0.10/audio/profiles/mp3/pipeline "audio/x-raw-int,rate=44100,channels=2 ! lame name=enc preset=1006 ! id3v2mux"References
