xwax - Digital vinyl on Linux
xwax is vinyl emulation software for Linux. It allows DJs and
turntablists to playback digital audio files (MP3, Ogg Vorbis, FLAC, AAC and
more), controlled using a normal pair of turntables via timecoded
vinyls.
The ordering of options is important. Most options apply to
subsequent music libraries or decks, which can be given multiple times. See
the EXAMPLES below.
- -l path
- Scan the music library or playlist at the given path.
- -t name
- Use the named timecode for subsequent decks. See -h for a list of valid
timecodes. You will need the corresponding timecode signal on vinyl to
control playback.
- -33
- Set the reference playback speed for subsequent decks to 33 and one third
revolutions per minute. This is the default.
- -45
- Set the reference playback speed for subsequent decks to 45 revolutions
per minute.
- -c
- Protect subsequent decks against certain operations during playback.
- -u
- Allow all operations on a deck during playback. This is the inverse of the
-c option, and is the default.
- --phono
- Adjust the noise thresholds of subsequent decks to tolerate a
cartridge-level signal connected to a line-level audio interface. This is
a 'software pre-amp'. Unless your audio path has low noise, this will give
worse results or may not work at all; a true phono pre-amplifier is always
preferred.
- --line
- Set noise thresholds of subsequent decks to standard audio levels. This
reverses the effect of the --phono option, and is the default.
- -i path
- Use the given importer executable for subsequent decks.
- -s path
- Use the given scanner executable to scan subsequent music libraries.
- --dummy
- Create a deck which is not connected to any audio device, used for
testing.
- -k
- Lock into RAM any memory required for real-time use. This includes audio
tracks held in memory which can be large. Use ulimit -l to raise
the kernel's memory limit to allow this.
- -q n
- Change the real-time priority of the process. A priority of 0 gives the
process no priority, and is used for testing only.
- -g
[nxn][+n+n][/f]
- Change the geometry of the display in size, position and scale (zoom)
respectively. The size and position is passed to SDL, which may use it to
set the display mode, or size of an X window. See the
EXAMPLES.
- --no-decor
- Request to the window manager to create a 'frameless' window which does
not have the regular controls such as title bars and buttons. This can be
useful in conjunction with the -g flag for dedicated xwax
installations.
- -h
- Display the help message and default values.
The following options are available only when xwax is compiled
with ALSA support.
- -a device
- Create a deck which uses the given ALSA device (eg. plughw:0).
- -r hz
- Set the sample rate for subsequent decks.
- -m
milliseconds
- Set the ALSA buffer time for subsequent decks.
The following options are available only when xwax is compiled
with JACK support.
- -j name
- Create a deck which connects to JACK and registers under the given
name.
xwax does not set the sample rate for JACK devices; it uses the
sample rate given in the global JACK configuration.
The following options are available only when xwax is compiled
with OSS support.
- -d pathname
- Create a deck which uses the given OSS device (eg. /dev/dsp).
- -r hz
- Set the sample rate for subsequent decks.
- -b n
- Set the number of OSS buffers for subsequent decks.
- -f n
- Set the OSS buffer size (2^n bytes).
The following options are available only when xwax is compiled
with ALSA support.
- --dicer
device
- Use one or two Dicer controllers connected as the given ALSA device (eg.
hw:Dicer). See the section NOVATION DICER CONTROLS for more
information.
Adding a hardware controller results in control over subsequent
decks, up to the limit of the hardware.
The playback of each deck (direction, speed and position) is
controlled via the incoming timecode signal from the turntables. The
keyboard provides additional controls.
"C-" and "S-" means a keypress is combined
with the 'Control' or 'Shift' key, respectively.
Record selection controls:
- cursor up, cursor
down
- Move highlighted record up/down by one.
- page up, page down
- Scroll the record listing up/down by one page.
- left cursor, right
cursor
- Switch to the previous/next crate of records.
- tab
- Toggle between the current crate and the 'All records' crate.
- C-tab
- Toggle sort mode between: artist/track name, BPM and 'playlist' order.
Playlist order is the order in which records were returned from the
scanner.
- C-S-tab
- Re-scan the currently selected crate.
To filter the current list of records type a portion of a record
name. Separate multiple searches with a space, and use backspace to
delete.
Deck-specific controls:
Deck 0 |
Deck 1 |
Deck 2 |
F1 |
F5 |
F9 |
Load currently selected track to this deck |
F2 |
F6 |
F10 |
Reset start of track to the current position |
F3 |
F7 |
F11 |
Toggle timecode control on/off |
C-F3 |
C-F7 |
C-F11 |
Cycle between available timecodes |
The "available timecodes" are those which have been the
subject of any -t flag on the command line. Audio display
controls:
- +, -
- Zoom in/out the close-up audio meters for all decks.
2-deck setup using one directory of music and OSS devices:
xwax -l ~/music -d /dev/dsp -d /dev/dsp1
As above, but using ALSA devices:
xwax -l ~/music -d hw:0 -d hw:1
2-deck setup using a different timecode on each deck:
xwax -l ~/music -t serato_2a -d hw:0 -t mixvibes_v2 -d
hw:1
As above, but with the second deck at 45 RPM:
xwax -l ~/music -t serato_2a -d hw:0 -t mixvibes_v2 -45
-d hw:1
Default to the same timecode, but allow switching at runtime:
xwax -l ~/music -t serato_2a -t mixvibes_v2 -d hw:0 -d
hw:1
3-deck setup with the third deck at a higher sample rate:
xwax -l ~/music -r 48000 -a hw:0 -a hw:1 -r 96000 -a
hw:2
Using all three device types simultaneously, one deck on each:
xwax -l ~/music -a hw:0 -d /dev/dsp1 -j jack0
Scan multiple music libraries:
xwax -l ~/music -l ~/sounds -l ~/mixes -a hw:0
Scan a second music library using a custom script:
xwax -l ~/music -i ./custom-scan -l ~/sounds -a
hw:0
Control two decks with Dicer hardware:
xwax --dicer hw:Dicer -a hw:0 -a hw:1
Use a high resolution and enlarge the user interface:
xwax -g 1920x1200/1.8 -a hw:0
