TrueCrypt

Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux
Main Features:

* Creates a virtual encrypted disk within a file and mounts it as a real disk.

* Encrypts an entire partition or storage device such as USB flash drive or hard drive.

* Encrypts a partition or drive where Windows is installed (pre-boot authentication).

* Encryption is automatic, real-time (on-the-fly) and transparent.

* Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:

1) Hidden volume (steganography – more information may be found here).

2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data).

* Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS.

RazorLame – Freeware

RazorLame is a so-called front-end for use with LAME.

LAME is a great MP3-Encoder: it’s very fast, it produces
high-quality files, has many advanced features (like
Variable Bitrates and Joint-Stereo), and it’s open source.

Unfortunately, it is a command line utility, and that is
where RazorLame comes in: it provides an easy-to-use
graphical user-interface which makes MP3-encoding even
easier!

You can find more about LAME at http://www.mp3dev.org/
