CDex can extract the data directly (digital) from an Audio CD, which is generally called a CD Ripper or a CDDA utility. The resulting audio file can be a plain WAV file (useful for making compilation audio CDs) or the ripped audio data can be compressed using an audio encoder. Many encoders are supported, to name a few:
1. Lame MP3 encoder 2. Internal MP2 encoder 3. APE lossles audio format 4. Ogg Vorbis encoder 5. The Windows MP3 encoder (Fraunhofer MP3 encoder) 6. NTT VQF encoder 7. FAAC encoder 8. Windows WMA8 encoder
In addition, WAV files on the hard drive can be converted to a Compressed Audio File (and visa versa). CDex also supports many audio file tag formats like the ID3V1 and ID3V2 tags, which can be automatically inserted as part of the ripping process.
