cdplay play 1

Play the first track from a audio CD. Use cdplay to play the whole CD. Use cdplay stop when had enough.


Get a free coffee cup holder :))). (Eject the CD ROM tray). This command defaults to the CDROM, but could be used to eject other removable media by specifying the mount point or device. E.g., I can eject the zipdisk from a parallel-port (external) zipdrive (as root) using: eject /dev/sda4.

I often use eject (as root) when the media does not want to eject when I press the button on the CDROM.

play my_file.wav

Play a wave file.

rec my_file.wav

Record a wave file from my microphone.

mpg123 my_file.mp3

Play an mp3 file.

mpg123 -w my_file.wav my_file.mp3

Create a wave audio file from an mp3 audio file. Useful if you wanted to write a regular audio CD from mp3s--you have to convert the mp3s to the *.wav format first. Don't be surprised the conversion is slow--decompressing mp3s is very processor intensive.

xmms &

freeamp &

(in X terminal) Another GUI mp3 player.

lame input_file output_file

MP3 encoder. You may need to download and install it yourself (standard Linux distributions avoid supplying it because of disagreement about patents on the mp3 compression technique).


(in X terminal) Start the program to download mp3 files that other users of napster have displayed for downloading. You may share your mp3s too. Really cool, while it lasts. Gnutella and FreeNet will soon replace them->it gets even cooler.

cdparanoia -B "1-"

(CD ripper) Read the contents of an audio CD and save it into wavefiles in the current directories, one track per wavefile. The "1-" means "from track 1 to the last". -B forces putting each track into a separate file.
