You can use the cdrw command to create audio CDs from individual audio tracks or from .au and .wav files.
The supported audio formats are:
| 
 Format  | 
 Description  | 
|---|---|
| 
 sun  | 
 Sun .au files with data in Red Book CDDA format  | 
| 
 wav  | 
 RIFF (.wav) files with data in Red Book CDDA format  | 
| 
 cda  | 
 .cda files with raw CD audio data, which is 16–bit PCM stereo at 44.1 kHz sample rate in little-endian byte order)  | 
| 
 aur  | 
 .aur files with raw CD data in big-endian byte order  | 
If no audio format is specified, the cdrw command tries to determine the audio file format based on the file extension. The case of the characters in the extension is ignored.
