cdplay - play audio compact disks SYNOPSIS
cdplay [ -a]|[-r] DESCRIPTION
Cdplay is an audio-cdplayer it can be used interactively or non-interactively. With no flags cdplay is used interactively. When used inter- actively cdplay can be either in non-playing or playing mode. In non-playing mode you can select tracks to be played. In playing mode cdplay shows the track-time, remaining track-time, total-time and remaining total-time. Cdplay assumes the drive to be at /dev/cd0. During non-playing mode the following commands are available: cursor-up/down browse through the track-list spacebar add track to the play-list backspace remove a track from the play-list s start playing the tracks in the play-list. When the play-list is empty start playing from the current position in the track-list until the end of the cd p play the track on the current position in the track-list r play all tracks in a random order (shuffle play) e exit cdplay During playing mode the following commands are available: s stop playing, return to non-playing mode spacebar pause/resume current track cursor-up/down skip to next/previous track OPTIONS
When one of these options is used cdplay does everything in the background. -a Play all tracks, cdplay tells the drive to play all tracks and then it immediately returns to the user -r Play all tracks in random order (shuffle play). Cdplay forks of a new process which starts up a track, during that track it sleeps. When the track is finished it wakes up to start the next track and goes to sleep again. The parent process immediately returns to the user. BUGS
Cdplay does not sense if a cd has changed, so don't switch cd's. If you want to play another cd you have to insert the new cd and start cdplay again. AUTHOR

cdplay -- compact disc player SYNOPSIS
cdplay [-a audio device] [-f device] [command ...] DESCRIPTION
cdplay is a program to control the audio features of a CD-ROM drive. If no command is given, then cdplay enters interactive mode, reading commands from the standard input. The following options are available: -a audio device Specify the audio device to use. Used only in digital transfer mode. If not specified, the environment variables AUDIODEV and SPEAKER will be tried (in this order) to find the device; as a last resort, /dev/sound will be used. If the ``-a'' command line option is used, or the CDPLAY_DIGITAL environment variable is present, digital transfer mode is switched on automatically. -f device Specify the control device to use. Both absolute paths and paths relative to /dev are accepted. The suffix 'c' (or 'd' on some architectures, see disklabel(8) for details) is added to the device name if needed. If the device not specified, the environment variables MUSIC_CD, CD_DRIVE, DISC and CDPLAY will be tried (in this order) to find the device. The available commands are listed below. Only as many characters as are required to uniquely identify a command need be specified. The word play can be omitted in all cases. play [first_track [last_track]] Play from track first_track to track last_track. The first track has number 1. play [start_m:start_s.start_f [end_m:end_s.end_f]] Play from the absolute address (MSF) defined by start_m in minutes, start_s, in seconds and start_f (frame number) to the abso- lute address defined by end_m in minutes, end_s, in seconds and end_f (frame number). Minutes are in the range 0-99. Seconds are in the range 0-59. Frame numbers are in the range 0-74. play [#start_block [length]] Play starting from the logical block start_block using length logical blocks. next Skip to the next track. prev Skip to the previous track. pause Stop playing. Do not stop the disc. resume Resume playing. Used after the pause command. shuffle Select shuffle play. Only valid in interactive mode. single [track] Pick a single track and play it repeatedly. If a track argument is not given the single command will shut shuffle mode off and play the disc normally. Only valid in interactive mode. skip Skip to another track. Only valid when shuffle play is selected. stop Stop the disc. eject Eject the disc. close Inject the disc. volume left_channel right_channel Set the volume of left channel to left_channel and the volume of right channel to right_channel. Allowed values are in the range 0-255. volume value Set the volume of both left channel right channel to value. Allowed values are in the range 0-255. volume mute Turn the sound off. volume mono Set the mono mode. volume stereo Set the stereo mode. volume left Play the left subtrack on both left and right channels. volume right Play the right subtrack on both left and right channels. info Print the table of contents. status Display the current audio, media and volume status. digital n Turn on digital transfer mode. In this mode, cdplay reads digital data from disc and sends it to an audio device. A SCSI or ATAPI CD-ROM is required; and the audio device must support CD audio format (44100 Hz sampling rate, 16-bit stereo samples). Audio data are read and written in groups of n frames (5 by default, or 1/15 seconds). analog Switch from digital back to analog mode. help Print the list of available commands. reset Perform the hardware reset of the device. set msf Set minute-second-frame ioctl mode (default). set lba Set LBA ioctl mode. quit Quit the program.
