Audacity

Audacity is a free, easy-to-use, cross-platform audio editor and recorder for Windows, Mac OS X, GNU/Linux, and other operating systems.

You can use Audacity to:

• Record live audio.
• Convert tapes and records into digital recordings or CDs
• Edit Ogg Vorbis, MP3, and WAV sound files.

Use LAME

Exporting audio as an MP3 is easy to do in Audacity and uses LAME as the in-built encoder. If you want to make use of extra LAME settings, such as the lowpass setting, then you'll need to do the following:

File > Export > Save as type: (external program)

Then in the Format Options > Command: field enter:

C:\Path\To\Lame\lame.exe - -V 0 --lowpass 16 "%f"
