Disk-At-Once Recording of Audio and Data CD-Rs/CD-RWs
Here are some applications of cdrdao:
The following command will copy the CD in the source drive
specified with option
cdrdao copy --source-device 0,2,0 --device 0,5,0 --buffers 64
On the fly copying is selected with option
If the source CD contains audio tracks and the source drive is
slow you should consider to reduce the audio extraction
qualtiy with option
The standard generic SCSI interface of the Linux kernel cannot handle multiple commands in parallel. Since the reading and the writing part of cdrdao use the generic SCSI interface mutual blocking will occur. This results in low fill rates of cdrdao's ring buffer and very likely produces buffer under runs.
To avoid these problems you should apply Heiko Eißfeldt's sg-buffer
patch. It is available for 2.0.x and 2.1.x kernels. For
2.2.x kernels the
I strongly recommend to perform some simulation runs before trying real writing.
Creation of a CD with Live MusicAssume you have a WAVE file
to create a CD without any pre-gaps between the tracks.
Creation of a CD with a "Secret" Pre-gap before 1st TrackThe toc-file
CD_DAwill create a CD with a pre-gap before track 1 that contains audio data from file
