The higher the quality, the more disk space the file will take. The quality settings appear in the Advanced tab, after you have selected a particular Encoder that supports these features.

* '''ABR (Average Bitrate) Encoding.''' Like VBR (Variable Bitrate), this mode allows for higher and lower bitrates, while maintaining an overall average. It is better quality than CBR, and produces smaller file sizes than VBR.  Select the Average bitrate you want to use in the Target Bitrate box.

* '''CBR (Constant Bitrate) Encoding.''' This mode encodes the entire file at the same bitrate. The lower the selected bitrate, the more music you can fit on the disk but the poorer the sound quality. The default is 128 kilobits of data per second of music. This is the number that most people agree maintains CD quality sound while giving an excellent compression ratio. If you will be listening on home stereo equipment rather than your computer, you may prefer the 160 or 192 kilobit settings, or higher (or VBR).<br/>''Note: 128 kb/s has been the standard for a long time with slow internet connections and high storage prices. It is not recommended nowadays as it has perceibable lower quality than the original CD (except on portable devices with low quality ear phones). Use 192 (or 160) instead. Above 192 the differences are not significant and cannot be heard by normal listeners (with medium to good equipment).

* '''VBR (Variable Bitrate) Encoding.''' With VBR, you select a bitrate (or a mode, from low to high), and the encoder varies the bitrate throughout the track while closely matching your selected quality level. The file size, however, is unpredictable (but often lower than CBR).<br/>You have five bitrate choices to balance compact size vs. sound quality:

** Extreme. Archival quality. This would be a good choice for top quality home stereo equipment.
 
** Fast Mode. This provides the fastest encoding, but the quality is not as good as the “Normal” setting.
