cdda2wav, copier un CD Audio

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 icedax le remplace.

Exemple de sortie

[cedric@dskstd cdaudio]$ cdda2wav -vall cddb=0 -paranoia -B -D /dev/sr0

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.
