utility, with support for playing audio CDs and Track-At-Once (TAO) CD
If no command is given,
interactive mode, reading commands from the standard input.
The options are as follows:
- Specifies a CDDB host [default: freedb.freedb.org:cddb].
- Specifies the name of the CD device, such as
/dev/rcd0c. Both absolute and relative paths to
/dev filenames are possible; the raw partition
name is added if needed.
- Silent mode. Do not print table headers or human-readable comments.
- Verbose mode. A second occurrence of
even more information to be printed.
The available commands are listed below. Only as many characters

play is assumed.

In case of multiple matches, reissue the command with
- Print the disc ID that will be used for matching with the CDDB.
- Play specified tracks from disk. Unlike
CD player need not be connected to an audio device; instead it rips tracks
from disk and outputs audio data to the default audio device. Both
individual tracks and track ranges may be specified. If range is specified
in descending order tracks will be played in descending order. If the
first value in the range is omitted, tracks from first track on disk to
the specified one will be played. If the last value in the range is
omitted, tracks from the specified track to the last track on disk will be
- Rip specified tracks from disk. Audio tracks are saved as WAVE sound
files. All tracks will be saved in the current working directory. If

- Stop playing. Do not stop the disc.
- Play from track1 to track2; an
optional index point can be specified for each track. If only one track is
specified, play from that track to the end of the disc. If no tracks are
specified, play the whole disc.
- Play from the absolute address (MSF) defined by m1
in minutes, s1 in seconds, frame number
f1, to the absolute address defined by
m2 in minutes, s2 in seconds,
frame number f2. If a track number is specified
(trX), then the minutes, seconds, and frame numbers
are relative to the start of that track. Minutes are in the range
0–99. Seconds are in the range 0–59. Frame numbers are in
the range 0–74.
- Play starting from the logical block using
len logical blocks.

The options are as follows:
- Write files as audio tracks. File formats of audio tracks may be CDDA
or WAVE with 2 channels of PCM audio, signed 16-bit (little endian)
values sampled at 44100 Hz.
- Write files as data tracks (the default).
- Specify a write speed for tracks. speed may be a
numerical value between 1 and the maximum speed supported by the media
and drive, or one of the literal strings “auto” or
“max”, meaning the optimal or maximum speed detected.
The default speed is “auto”.
- Set the volume of the left channel to left_channel
and the volume of the right channel to
right_channel. Allowed values are in the range

the right subtrack on both left and right channels; set mono mode; set
stereo mode; turn the sound off.
