grip [-d <device>] [-s] [-l]

Grip is a gtk-based cd-player and cd-ripper. It has the ripping capabilities of cdparanoia builtin, but can also use external rippers (such as cdda2wav). It also provides an automated frontend for MP3 encoders, letting you take a disc and transform it easily straight into MP3s. The CDDB protocol is supported for retrieving track information from disc database servers. Grip works with DigitalDJ to provide a unified "computerized" version of your music collection.

Grip is designed to work closely with DigitalDJ, my SQL-based mp3 jukebox system (although it does not require it).

These are the command-line options for grip:

-c,  --config=CONFIG

Specify the config file to use (in your home dir)

-d,  --device=DEVICE

Use <device> as the cd-rom device (default: /dev/cdrom).

-s,  --small

Launch grip in a "small" (cd-only) mode.

-l,  --local

"local" mode -- don't try to use CDDB.

--no-redirect

Do not do I/O redirection

-v,  --version

Print version string, and exit.

--verbose

Verbose (debug) mode.

The most handy way to launch Grip is from your window manager's doc. A dock icon is included with the distribution.

Grip's operation should be pretty self-explanatory. Tracks to rip are selected with the right mouse button. To select all tracks on the disc, click the "Rip" column label. When you select "Rip" or "MP3-encode" from the "Rip" page, Grip will rip or rip/encode the tracks you have selected. If you select "Rip partial track", only the current select of the current track will be ripped or encoded. Start/End sector values are ignored if partial track ripping is not enabled.

The "Config" menu allows you to configure your ripping program and your CDDB database. Rip/Encode/ID3 options are only available in Grip.

Here are the options:

Don't interrupt playback on exit/startup

If this is not selected, Grip will stop play when it starts and when it stops.

Rewind when stopped

If selected, Grip will rewind to the first track when play is stopped.

Startup with first track if not playing

If this is not selected, Grip will begin with whatever track the cd-player played last.

Reshuffle before each playback

If selected, Grip will re-randomize the tracks each time playback begins when in shuffle-play mode.

Ripper

This allows you to select one of the preset rippers. This will fill in sensible default parameters for calling the ripper. If you select "grip (cdparanoia)", Grip will use its builtin version of cdparanoia (only available if paranoia has been compiled in). If the builtin ripper is selected, the following options are available:

Disable paranoia

Disables all paranoia checking.

Disable extra paranoia

Only cdda2wav-style overlap checking will be done.

Disable scratch detection

Do not look for scratches.

Disable scratch repair

Disable scratch repair (still detect)

Ripping executable

This should be the full path to the program you want to use to rip tracks with.

Ripping command-line

These are the arguments that will be passed to the ripping program. The '%' switches are translated as follows:

%t

Track to be ripped

%b

Begin sector to be ripped (0 is start of track)

%e

End sector of track

%f

Filename to put .wav data to

Rip file format

This specifies the format of the filename to write ripped data to. The '%' switches are translated as follows:

%n

Name of track being ripped

%t

Number of track being ripped

%a

Artist of current track

%A

Artist of the current disc

%d

Name of current disc

%b

Begin sector to be ripped (0 is start of track)

%e

End sector of track

%c

cdrom device

%i

CDDB discid in hex format

%g

ID3 genre tag as a number

%G

ID3 genre tag as a word

Adding a '*' between the '%' and the switch will cause underscoring of the field to be skipped.

Rip 'nice' value

The 'nice' (priority) level to run the rip at.

Max non-encoded .wav's

The maximum number of non-encoded .wav files Grip will keep around before pausing ripping.

Auto-rip on insert

If selected, Grip will automatically select all tracks and begin ripping when a new (ie: no local disc data) disc is inserted.

Auto-eject after rip

If selected, Grip will automatically eject the disc when ripping is finished.

Wav filter command

This command will be run after ripping but before encoding. It can be used to call a program to manipulate the .wav file in some way (such as doing normalization). It accepts a single switch, %f, which translates as the ripped .wav file.

Encoder

This allows you to select one of the preset rippers. This will fill in sensible default parameters for calling the encoder.

MP3 executable

This should be the full path to the program you want to use to MP3-encode tracks with.

MP3 command-line

These are the arguments that will be passed to the MP3 encoder. The '%' switches are translated as follows:

%b

Encode bitrate (kbits/sec)

%f

Filename of the .wav data to be encoded

%o

Filename to save mp3 data to

MP3 file format

This specifies the format of the filename to write MP3 data to. The '%' switches are the same as those used in the rip file format.

Delete .wav after encoding?

If selected, this option will (surprise!) delete the ripped .wav file after encoding.

Insert into SQL database

If selected, and DigitalDJ is installed, Grip will place the song information into DigitalDJ's song database.

Number of CPUs to use

This is the number of simultaneous encode processes allowed. If you have an SMP system, increase this number to use more processes. Note that Grip must be restarted for changes in this option to take effect.

MP3 'nice' value

The 'nice' (priority) level to run the MP3 encode at.

ID3 Executable

The full path to the program that will add ID3 tags to an MP3 file

ID3 Command-line

The arguments to be passed to the ID3 program. The % switches are translated as:

%n

Name of track

%t

Number of track

%a

Artist of current track

%A

Artist of the current disc

%d

Name of current disc

%g

ID3 genre tag as a number

%G

ID3 genre tag as a word

%y

Year of track

%f

Name of the MP3 file

Add ID3 tags

If selected this option will cause ID3 tags to be added to each MP3 file after it is encoded.

Primary/Secondary CDDB server

These are your servers for looking up disc information over the net. If the disc is not found on the primary server, the secondary server will be checked.

DB server

The address of the CDDB server you wish to use.

DB CGI path

The path to the script on the server that handles HTTP requests. This is generally "~cddb/cddb.cgi" or "cgi-bin/cddb.cgi".

Perform CDDB lookup automatically

If selected, Grip will always try to look up an unknown disc. If not selected, lookup must be initiated manually.

Use proxy server

If selected, CDDB requests will be sent through an HTTP proxy (useful for people behind firewalls).

Get server from 'http_proxy' env. var:

If set, Grip will try to read the http server/port information from the environment variable "http_proxy", which should take the form "http://server:port".

Proxy server

The address of the HTTP proxy server to be used.

Proxy port

The port to talk to the proxy on.

Output directory

The directory to place WAV and MP3 files in. The same '%' switches as in the rip/encode filenames can be used.

Convert spaces to underscores

If selected, this will cause all spaces in filenames to underscores.

Also underscore

A list of characters to replace with underscores when constructing filenames.

Email address

The email address to be used as a reply address when submitting CDDB entries and bug reports.

CD update program

This program will be run whenever a disc is put in the drive. All sensible '%' switches can be used. I use this to call a program that generates a web page that tells what CD I'm currently playing.

Keep application minimum size

If selected, Grip will always try to keep its window a the minimum size possible.

I have declined to sign a license agreement with Escient, the company who owns "www.cddb.com" and runs the CDDB server "us.cddb.com". Their license would (among other things) have required me to place advertisements in Grip and restrict you, the user, to use only their databases. I am against this commercial use of the track information submitted by users such as yourself. For this reason, I encourage you to use free servers, such as "gnudb.gnudb.org".
