XWAX(1) General Commands Manual XWAX(1) 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), con- trolled using a normal pair of turntables via timecoded vinyls. OPTIONS The ordering of options is important. Most options apply to subsequent mu- sic libraries or decks, which can be given multiple times. See the EXAM- PLES 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 revolu- tions 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 car- tridge-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-am- plifier 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. ALSA DEVICE OPTIONS 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). --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 au- dible 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. -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. OSS DEVICE OPTIONS 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). --rate hz Set the sample rate for subsequent decks. The default for OSS de- vices is 48000Hz. -b n Set the number of OSS buffers for subsequent decks. -f n Set the OSS buffer size (2^n bytes). 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 in- formation. 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' or- der. 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. Sep- arate 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. 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 -l ~/music -d /dev/dsp -d /dev/dsp1 As above, but using ALSA devices: xwax -l ~/music -a hw:0 -a hw:1 2-deck setup using a different timecode on each deck: xwax -l ~/music -t serato_2a -a hw:0 -t mixvibes_v2 -a hw:1 As above, but with the second deck at 45 RPM: xwax -l ~/music -t serato_2a -a hw:0 -t mixvibes_v2 -45 -a hw:1 Default to the same timecode, but allow switching at runtime: xwax -l ~/music -t serato_2a -t mixvibes_v2 -a hw:0 -a hw:1 3-deck setup with the third deck at a higher sample rate: xwax -l ~/music --rate 48000 -a hw:0 -a hw:1 --rate 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 HOMEPAGE http://xwax.org/ AUTHOR Mark Hills <mark@xwax.org> XWAX(1)
