Esta vez voy a explicar cómo ripear nuestro CD de audio favorito (original, por supuesto) en formato mp3 en GNU/Linux utilizando el codec LAME, de forma extremadamente sencilla!
Como la mayoría de los artículos de este blog, el procedimiento se realiza desde la consola. Primero se debe insertar el CD de audio y copiar los archivos *.wav a un directorio destino. Para ello es necesario montar el CDROM, en Red Hat y derivados se hace mediante el comando:
mount /media/cdrom
En otras distribuciones tal vez deba especificarse el tipo de sistema de archivos:
mount -t iso9660 /dev/cdrom /media/cdrom
Sino, en Nautilus es posible acceder al CD utilizando la URL:
"cdda:///dev/sdr0"
O en Konqueror es posible utilizar:
"audiocd:/"
Una vez montado el CD de audio y copiados los archivos *.wav es posible realizar la conversión a *.mp3 utilizando el codec lame. Cambiar al directorio donde se han copiado los archivos *.wav y ejecutar:
for track in *.wav; do lame -m j -b 192 "$track" ; done
Para cada archivo *.wav en el directorio actual, realiza la conversión a MP3 utilizando "lame". La opción "-m" se utiliza para especificar el modo, en este caso "joint stereo", y la opción "-b" se utiliza para especificar el bitrate, en este caso 192Kbps.
Eso es todo!
Extremadamente sencillo.
