Plextor Plexwriter Another Question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,
cdrdao is for writing in disk at once mode.
I am using it to write my audio cd disks.
I am not sure if i understand what you want to do, but
you among other things, can do the following with cdrdao.
read an audio cd to create a toc file, a table of contents file that is
used for writing a cd. it then creates a file data.bin containing the
music.
The toc file describes where in data.bin, the various tracks start, what 
the pregap is etc.
When i make a cd from my own wav files, i use it slightly differently.
Each song is in its own wav file.
If one gives a length of zero for the file, cdrdao assumes you want to 
use the full file as one track.  You can specify the length of the pregap
(silence between songs), for each track.  The pregaps can differ in length 
or be ommitted.
Note the wav files must be recorded at cd quality.
ie. they must have a sample rate of 44100, be in sterio and be at 16 bit 
per
sample.
If the files are not in that format, one can use sox to convert them 
before you write.
hth, Willem
