... encoder available for Linux at the present time is the closed source Nero encoder Actually, I'm not so sure about that. I've run some tests using FFmpeg (Debian Wheezy version), and some of the results show better sound quality than the Nero encoder :o Unfortunately, using Audacity's built in ...
