====== cdda2wav, copier un CD Audio ======
===== Exécuter =====
Cette commande permet d'extraire les pistes audios du CD en fichiers WAV. Pour un CD Audio de 74 minutes, prévoyez un espace disque de 700 Mo. Les pistes audios seront extraites dans le dossier courant.
Dans l'exemple ci-dessous, le CD Audio est accessible à l'adresse ''/dev/sr0''. C'est à modifier suivant votre configuration.
cdda2wav -vall cddb=0 -paranoia -B -D /dev/sr0
Sous Debian 9, ''cdda2wav'' n'est pas disponible. Le programme [[informatique:applications:icedax|icedax]] le remplace.
__Exemple de sortie__
[cedric@dskstd cdaudio]$ cdda2wav -vall cddb=0 -paranoia -B -D /dev/sr0

===== Convertir =====
Les pistes audios extraites pas ''cdda2wav'', sont au format WAV. Pour les convertir en fichier OPUS, je vous propose la commande suivante :
for f in *.* ; do opusenc --bitrate 128 "$f" "${f%.*}_128k.opus"; done
Cela suppose que ''opusenc'' soit déployer sur votre configuration.
