Debian has a very strict policy on free and legal software. This helps keep everyone honest, but sometimes a pragmatic approach is called for. MP3 is a file format that is patent encumbered - but also in universal use.

I could use the supplied Ogg Vorbis tools but then my music wouldn't work everywhere I want it to.

So I want to install Lame which is only available in source.

http://sourceforge.net/projects/lame/files/

Download and extract


cd lame-398-2/
# install a build environment by pulling in the build dependencies for something useful (I chose php)
sudo apt-get build-dep php5
sudo aptitude install fakeroot
# check build dependencies of lame
cat debian/control
# and install them
sudo aptitude install nasm libsndfile1-dev
chmod 700 debian/rules
dpkg-buildpackage -rfakeroot -uc -b
sudo dpkg -i ../lame_3.98.1_i386.deb ../libmp3lame0_3.98.1_i386.deb
