1.

In order to obtain perfect copies I don't recommend the "on-the-fly" option.

In audio, the best way is get the WAV files from audio CD and copy

them to CD-R. Is slower but you make sure that the quality is the best.


If you do not have a powerful computer neither a recorder with a great

buffer you don't make audio copies "on-the-fly".



2.

The recording is in WAV format, 16 bits, stereo and 44.100 Hz rate, because

this is the CD-R copy format. Also CDDOIT record to 44.101 Hz, but you must

convert to 44.100 before the CD-R copy.

CDDOIT has an menu option to make conversions from no-44.100 Hz

to 44.100 Hz (Go to menu AUDIO, option nº 4 to convert it).


Recording of audio is performed by SOX.

If your SOX version is older or the audio recording quality is not good

try the 44101 Hz recording.



3.

The extraction of audio is made with CDPARANOIA. CDDOIT runs

CDPARANOIA track by track from the Audio CD (although it allows to obtain

all the audio tracks of the CD at once) since I have verified better results with this method.

CDDOIT detect automatically the number of tracks from the audio CD.



4.

In order to copy audio cd's CDDOIT it uses the configuration file of

CDRECORD for the copy, the file is: / etc/cdrecord.conf

You must to indicate device SCSI, the speed of recording and the size

of the buffer that will be used.

Go to menu OTHERS, oprtion 10 to modify the 'cdrecord.conf' file easy.

CDDOIT allows the visualization of SCSI devices that CDRECORD

recognizes.

Read the documentation of CDRECORD about it.



5.

CDRECORD uses only devices SCSI, reason why if you have a recorder

IDE/ATAPI you must have activated SCSI emulation to detects it.

In order to know if CDRECORD has detected devices executes the option

of menu that allows the visualization of the SCSI devices that CDRECORD

recognizes.

If CDRECORD does not detect your recorder, you must to activate SCSI

emulation. If your kernel is recent adding these lines to the

file /etc/modules.conf:


options ide-cd ignore=hd? # tell the ide-cd module to ignore hd? (? is your device letter)

alias scd0 sr_mod # load sr_mod upon access of scd0

pre-install sg modprobe ide-scsi # before sg, load ide-scsi

pre-install sr_mod modprobe ide-scsi # before sr_mod, load ide-scsi


and this line to the / etc/lilo.conf file:


image=/boot/vmlinuz-2.2.XX-XX

label=XXXX

read-only

root=/dev/hdXX

append="hd?=ide-scsi" <<<---- ADD THIS LINE

Where ? is the device letter of your CD-Recorder.


SCSI emulation would have to activate.

If even so the emulation does not activate I recommend you

read the"CDWriting-howto" document which you can get it in www.linuxdoc.org

and the documentation of CDRECORD (the file "readme.atapi")



6.

If you include CDDOIT in the menu through the menu editor of GNOME

or KDE, you must indicate that it is executed through a terminal, otherwise,

when executing it you will not be able to see it.

It remembers that in the terminal you can select text with the mouse,

copy and paste where you wish.


Example to run CDDOIT in a xterm window:


xterm -bg yellow4 -fg white -title 'CDDOIT - CD Creation & Sound' -cr white -e cddoit



7.

Multisession data:

The data image files for multisession data are special. The first data image

to copy is different from the next data images. CDDOIT warning about this.

Be carefull.


IMPORTANT: CDDOIT use the MKISOFS command from the CDRTOOLS (CDRECORD package).

Not use the standard UNIX/LINUX command.


8.

In multisession audio you must to close the CD-R after copy the last audio

track. Go menu AUDIO CD-R, option nº 8.



9.

In audio conversions between diferent formats, the sound quality maybe not the

best. (See menu AUDIO, option nº 10)


10.

Audio recording programs:

- Don't cover up programs at the same date/time. SOX no start until the previous

SOX finish.



11.

The CDPlayer uses the soundcard (/dev/dsp).


12.

In Linux SuSE 8.1 cdrecord reads only /etc/default/cdrecord as

his config-file and not /etc/cdrecord.conf. The solution is create

the symbolic link /etc/cdrecord.conf to /etc/default/cdrecord with

the "ln" command:

ln -s /etc/cdrecord.conf /etc/default/cdrecord
