The cdrecord command permits you to create audio and information CDs from the command line, writing to CD-recordable (CD-R) and CD-rewritable (CD-RW) drives. This command is mentioned within the following part. growing an audio CD with cdrecord you should use the cdrecord command to create both info or tune CDs. you could create an information CD by way of constructing a separate dossier approach and copying the total picture of that dossier process to CD. growing an audio CD involves deciding on the audio tracks you need to reproduction and copying all of them right now to the CD. This part makes a speciality of utilizing cdrecord to create audio CDs. cdrecord can use audio records in . au, . wav, and . cdr codecs, immediately translating them while priceless. when you have audio records in different codecs, you could convert them to at least one of the supported codecs by utilizing the sox command (described formerly during this chapter). a method to create an audio CD is to take advantage of cdda2wav to extract (copy) the track tracks to a listing after which use cdrecord to write down them from the listing to the CD. Here’s an instance: be aware should you desire a graphical software for copying and burning CDs and DVDs, seek advice from Appendix A, which describes how you can use the K3B CD/DVD Burning Facility for burning CD photos. you may as well use that device for copying audio CDs. 1. Create a listing to carry the audio documents, and alter to that listing. (Make convinced the listing can delay to 660MB of data—less when you are burning fewer songs. ) for instance: # mkdir /tmp/cd # cd /tmp/cd 2. Insert the track CD into your CD-ROM force. (If a CD participant opens at the laptop, shut it. ) three. Extract the song tracks you will want through the use of the cdda2wav command. for instance: # cdda2wav -D /dev/cdrom -B This reads all of the song tracks from the CD-ROM force. The -B alternative says to output every one song to a separate dossier. by way of default, the cdda2wav command outputs the records to the WAV audio structure. 103 Part II: operating a Linux computer rather than extracting all songs, you could decide upon a unmarried music or a number tracks to extract. for instance, to extract tracks three via five, upload the -t3+5 alternative. To extract simply tune nine, upload -t9+9. To extract tune 7 throughout the finish of the CD, upload -t7. notice when you have a low-quality CD force or a less than perfect CD, cdda2wav is probably not the simplest ripping software. chances are you'll test cdparanoia -B to extract songs from the CD to harddrive as a substitute. four. while cdda2wav is completed, eliminate the tune CD and insert a clean CD into your writable CD force. five. Use the cdrecord command to write down the song tracks to the CD. for instance: # cdrecord -v dev=/dev/cdrom -audio *. wav the choices to cdrecord inform the command to create an audio CD (-audio) at the writable CD machine positioned at /dev/cdrom. The cdrecord command writes all . wav documents from the present listing. The -v choice reasons verbose output. 6. a good way to swap the order of the tracks, you could kind their names within the order you will want them written (instead of utilizing *. wav). in the event that your CD author helps greater speeds, you should use the rate choice to double (speed=2) or to quadruple (speed=4) the writing pace.
