If you'd like to encode a CD song into an MP3 file, and you have a copy of N2MP3 from Proteron Software, then:

1	Play or select the track you wish to encode.
2	Open the Mode menu and choose Encode This Track with N2MP3

If you wish encode an entire disc, simply open the mode menu and choose Encode Disc with N2MP3.

There are many other programs that can encode MP3s, although not automatically from Audion. One other is Audio Catalyst from Xing Technology Corporation.
