NAME
xwax - Digital vinyl on Linux
SYNOPSIS
xwax [options]
DESCRIPTION
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.
OPTIONS
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, --crate path
Scan for tracks or playlist at the given path. Tracks are grouped into a crate in the music
library.
--timecode name
Use the named timecode for subsequent decks. See --help 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.
--[no-]protect
Protect against loading new tracks or resetting the start of the track if the deck is playing.
Applies to subsequent decks, and the default is off.
--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.
--import path
Execute the given program to load tracks for playing. The program outputs a stream of signed,
little-endian, 16-bit, 2 channel audio on standard output.
--scan path
Execute the given program to scan music libraries. Applies to subsequent use of the --crate flag.
--dummy
Create a deck which is not connected to any audio device, used for testing.
--lock-ram
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.
--rtprio n
Change the real-time priority of the process. A priority of 0 gives the process no priority, and
is used for testing only.
--geometry [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 --geometry
flag for dedicated xwax installations.
-h, --help
Display the help message and default values.
ALSA DEVICE OPTIONS
The following options are available only when xwax is compiled with ALSA support.
--alsa device
Create a deck which uses the given ALSA device (eg. plughw:0).
--rate hz
Set the sample rate for subsequent decks. The default is to prefer 48000Hz, but use 44100Hz if
that is not available. To maintain best performance, only sample rates implemented by the
hardware are available.
--buffer samples
Set the ALSA buffer size for subsequent decks. Smaller is better for lower latencies and greater
responsiveness. Set too low and audible glitches will occur, with reports of underruns to the
console.
JACK DEVICE OPTIONS
The following options are available only when xwax is compiled with JACK support.
--jack 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.
OSS DEVICE OPTIONS
The following options are available only when xwax is compiled with OSS support.
--oss pathname
Create a deck which uses the given OSS device (eg. /dev/dsp).
--rate hz
Set the sample rate for subsequent decks. The default for OSS devices is 48000Hz.
--oss-buffers n
Set the number of buffers used by the OSS device. Applies to subsequent decks.
--oss-fragment n
Set the size of a buffer used by the OSS device. The actual buffer is 2^n bytes. Applies to
subsequent decks.
HARDWARE CONTROLLER OPTIONS
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.
KEYBOARD CONTROLS
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 --timecode flag on the command
line.
Audio display controls:
+, - Zoom in/out the close-up audio meters for all decks.
NOVATION DICER CONTROLS
The Novation Dicer provides hardware control of cue points. The controls are:
cue mode: dice button (1-5)
Jump to the specified cue point, or set it if unset.
loop-roll mode: dicer button (1-5)
"Punch" to the specified cue point, or set it if unset. Returns playback to normal when the button
is released.
mode button + dice button (1-5)
Clear the specified cue point.
The dice buttons are lit to show that the corresponding cue point is set.
EXAMPLES
2-deck setup using one directory of music and OSS devices:
xwax --crate ~/music --oss /dev/dsp --oss /dev/dsp1
As above, but using ALSA devices:
xwax --crate ~/music --alsa hw:0 --alsa hw:1
2-deck setup using a different timecode on each deck:
xwax --crate ~/music --timecode serato_2a --alsa hw:0 --timecode mixvibes_v2 --alsa hw:1
As above, but with the second deck at 45 RPM:
xwax --crate ~/music --timecode serato_2a --alsa hw:0 --timecode mixvibes_v2 -45 --alsa hw:1
Default to the same timecode, but allow switching at runtime:
xwax --crate ~/music --timecode serato_2a --timecode mixvibes_v2 --alsa hw:0 --alsa hw:1
3-deck setup with the third deck at a higher sample rate:
xwax --crate ~/music --rate 48000 --alsa hw:0 --alsa hw:1 --rate 96000 --alsa hw:2
Using all three device types simultaneously, one deck on each:
xwax --crate ~/music --alsa hw:0 --oss /dev/dsp1 -j jack0
Scan multiple music libraries:
xwax --crate ~/music --crate ~/sounds --crate ~/mixes --alsa hw:0
Scan a second music library using a custom script:
xwax --crate ~/music --scan ./custom-scan --crate ~/sounds --alsa hw:0
Control two decks with Dicer hardware:
xwax --dicer hw:Dicer --alsa hw:0 --alsa hw:1
Use a high resolution and enlarge the user interface:
xwax --geometry 1920x1200/1.8 --alsa hw:0
