<sect1>Writing audio CDs
|
||||
<p>
|
||||
Writing audio CDs is very similar to the steps described above for data
|
||||
CDs. You can choose between two techniques: DAO or TAO. TAO (track at
|
||||
once) is less suitable for music, because you will hear clicks between the
|
||||
individual tracks. It is described first anyways, because it is a little bit
|
||||
easier to deal with and DAO is not available for all drives yet.
|
||||
|
||||
Writing audio CDs is very similar to the steps described
|
||||
above for data CDs. There are two main differences. One, the audio CD consists of
|
||||
audio tracks, which are organized as separate images. So if you want to
|
||||
have ten tracks on your CD, you have to make ten images. The other
|
||||
difference is that the format of the images is not ISO-9660 (or whatever
|
||||
filesystem you prefer), but it is "16 bit stereo samples in PCM coding at
|
||||
44100 samples/second (44.1 kHz)".
|
||||
The main difference compared to writing data CD-Rs is the format of the
|
||||
images. ISO-9660 (or whatever filesystem you prefer) would not be suitable,
|
||||
because no audio CD player is able to deal with filesystems. Instead the
|
||||
audio data must be writen as "16 bit stereo samples in PCM coding at 44100
|
||||
samples/second (44.1 kHz)".
|
||||
|
||||
One utility to convert your sound files into the required format is sox.

Its usage is straightforward:

formats WAV and AU. So as long as your sound files have the extensions .wav

the size of the sound data to be a integer multiple of 2352 and to be
|
||||
greater than 705,600 bytes, which is not fullfilled for some WAV files. For

such files the usage of sox is needed to pad the audio data up to 2352

One notable exception are MPEG Layer 3 files, which can be converted to the

CD format with the command "mpg123 --cdr -s track1.mp3 > track1.cdr". The

|

One notable format not directly readable by cdrecord is MPEG Layer 3. To

convert files in this format to the CDR-format, you can use the command

"mpg123 --cdr - track1.mp3 > track1.cdr". The option --cdr ensures the

track is encoded in the required format (see above). Older versions of

mpg123 require -s instead of the plain - to write to stdout. The other
|
||||
direction (converting from WAV to MPEG) can be done with LAME for WAV-files
|
||||
(extract the track with cdda2wav from the audio CD and encode it into MP3
