Both cdrdao and cdrecord support DAO mode.
but cdrdao has several features that missing from cdrecord.
1. extract hidden Audio Tracks that live in the pregap of track 1.
2. provide more precise control for audio when record by using toc file.
Take the example from its website:
Assume you have a WAVE file |live.wav| that contains several
minutes of live musicand you want to divide it in tracks
every 5 minutes with further subdivisions by index marks.
You will have to create following toc-file |live.toc|:
CD_DA
TRACK AUDIO
FILE "live.wav" 0 5:0:0
INDEX 3:0:0
TRACK AUDIO
FILE "live.wav" 5:0:0 5:0:0
TRACK AUDIO
FILE "live.wav" 10:0:0 5:0:0
INDEX 2:0:0
...
Then use
|
cdrdao write live.toc
|
to create a CD without any pre-gaps between the tracks.
Also, as brasero support several backends, including
- growisofs
- cdrdao
- cdrecord.
cdrecord and growisofs are already in Solaris,
and I want to add cdrdao also.
