They released the 1.0 Final of the BonkEnc encoder / converter. You can download it here:
The BonkEnc Project - BonkEnc Home
I'm tellin' ya, this thing is AWESOME, and it's open source, totally free and very functional.
dbPowerAmp and other pay converters be darned - this is where it's at.
If you rip CD's and want to encode and convert your audio files, I really encourage you to give this thing a shot.
It uses Lame 3.97 with lots of options, and handles large and small file conversions, including 32 kbps audio book stuff.
Give it a shot - I can't imagine anybody being disappointed.
