10. Didžejanje s programom Mixxx¶
Mixxx je bil ustvarjen za enostavno učenje tako za novince, kot tudi izkušene didžeje.
This part of the manual provides you with directions for importing and managing you music collection and playing your tracks.
10.1. Opening Mixxx¶
Once you’ve installed Mixxx, start by opening Mixxx and import your music to the Mixxx library.
Double-click the Mixxx icon on the Desktop. Alternatively, browse your Windows start menu and click the Mixxx icon, or perform a search for
- Mac OSX
Double-click the Mixxx icon in the
Applicationsfolder. Alternatively, drag the Mixxx icon to the dock and double-click it there, or perform a search for
Simply type mixxx into the terminal, then hit Return. With some distributions like Ubuntu you can also double-click the Mixxx icon in the launcher. Alternatively, perform a search for
10.2. Importing your audio files¶
- Setup the music library
The first time you run Mixxx, you are asked to select a directory where your music is stored. By default, the dialog points to a location where music files are typically held.
Click Select Folder and Mixxx will scan your music library. Depending on the size of your library this could take some time. All of the supported music files Mixxx detects will be listed in the Library - View and edit your whole collection.
Mixxx automatically detects newly added tracks on each subsequent run. If you want to manually refresh your library without exiting (for example because you added or moved files), you can do this within the menu. If you want to rescan at every launch, select .
On Windows 7 and 8 the import dialog points to your Windows “Music“ Library, a special-purpose virtual folder. You can not use these virtual folders. Select a regular folder instead, usually “My Music“, like pictured above.
- Compatible files
Mixxx supports a variety of file formats: Wave (wav), Aiff (aiff, aif), MP3 (mp3), Ogg vorbis (ogg), FLAC (flac), and AAC (aac, m4a) if supported by your OS. DRM protected files, such as m4p files purchased in the iTunes Store, are not supported.
AAC (M4A) is supported on Windows Vista and Mac OSX 10.5 onwards. On Linux, Mixxx does not have AAC (M4A) playback support enabled by default due to licensing restrictions.
To enable playback of AAC (M4A) files, you can build Mixxx from source. http://www.mixxx.org/wiki/doku.php/compiling_on_linux#build_with_m4a_file_support
- Changing the music directory
The Mixxx music directory can always be changed at a later time in. You might want to run a library rescan afterwards, select in the menu.
- Import external libraries
If you have iTunes, Traktor or Rhythmbox installed, Mixxx allows you to access your tracks and playlists in the Mixxx library, see iTunes, Traktor, Rhythmbox - Using external libraries.
- Import remote files
You can not drag complete folders to the library because currently Mixxx can not recursively scan folders for compatible music files.
- Import music from CDs
Mixxx can not play music from Audio CDs. Convert the content to compatible files in good quality and add them to them Mixxx library. See https://en.wikipedia.org/wiki/Ripping
10.3. Loading Tracks¶
Tracks can be loaded into a deck in several ways:
Right-click the library track table: Right-clicking on a track in the table will present the options Load in Deck 1 and Load in Deck 2, among others. Making either selection will load a track into a deck.
By Uporaba tipkovnice to load the selected track from library track table.
Drag-and-drop from library track table: Dragging-and-dropping a track from the track table onto a waveform display will load a track into a deck.
Drag-and-drop from external file browser: Dragging-and-dropping a track from an external file browser directly onto a waveform display in Mixxx will load that track. This function also works with some other applications. For example, on Mac OS X, dragging-and-dropping a track from iTunes onto one of Mixxx’s waveform displays will load that track into a deck.
10.4. Finding Tracks (Search)¶
The search function searches for a match only in the current selected list (e.g. a playlist, a crate or even the whole library).
Activate the search input field by pressing CTRL + F (Windows/Linux) or CMD + F (Mac). Alternatively click into the search box.
Type your search term. Mixxx filters the tracks and retains only the ones that match the search term. Search terms can include an artist’s name, a song title, BPM, etc.
To clear the search string hit ESC or click the clear button right next to the input field.
Hit TAB to cycle between the search and the list of results in the library. Use the ARROW UP and ARROW DOWN keys to scroll in the list of results.
If the search input field has focus, the Mixxx keyboard shortcuts are disabled, see Uporaba tipkovnice.
10.4.1. Using search operators¶
Novo v verziji 1.11.
Search operators allow you to form more complex search queries. They allow you to limit certain search terms to particular properties of your tracks.
Mixxx supports the following filters:
Text filtering: For artist, album, genre, title, composer, comment, key
Numeric filtering: For year, track, bpm, duration, played, rating, bitrate
You can combine operators but there’s no way to do an “OR” search right now. The following example list all tracks by “Danger” that are rated 4 or 5:
Examples for text filtering
Examples for numeric filtering
artist: “com truise”
Note it doesn’t matter if you have space between the colon and the argument or not. Quotes must be used for multi-word text arguments.
Note that you can put a space between the colon but currently there must be no space between the operator and the number.
10.5. Previewing Tracks¶
Novo v verziji 1.11.
To pre-listen to a track, activate the Preview column in a library view. Clicking the icon in the library’s Preview column loads the selected track in a special Preview Deck that will only output sound in the headphones channel. Click the icon to stop the playback.
Alternatively, select a track from the track list of the Mixxx library, drag the track to the waveform view of the Preview Deck and click the Play button next to the waveform.
To display the Preview deck, press CTRL + 4 (Windows/Linux) or CMD + 4 (Mac).
10.6. Waveform displays¶
There are two main waveform displays in Mixxx that are used to display the waveform of the tracks you are mixing. These are useful because they allow you to see features in a track (like a breakdown) before you hear them.
Depending on the skin Mixxx displays either separate waveforms (default) or parallel waveforms. Select your preferred appearance in.
With some skins the waveform displays are aligned parallel to each other in order to make beatmatching easier, as it is possible to beatmatch visually by aligning the beats that appear in each waveform.
The mouse can be used on the waveforms to scratch, spin-back or throw the tracks. Right-clicking and dragging on the waveforms allows you to nudge the track and make temporary pitch adjustments. Using the mouse-wheel on the waveform zooms the waveform in or out. You can choose whether or not to synchronize the zoom level between the decks in. The waveform display is updated in realtime upon seeking.
There are two smaller waveform summary displays located adjacent to the main waveform displays. Clicking on a waveform summary allows you to seek through the track. These smaller displays show the waveform envelope of the entire track, and are useful because they allow DJs to see breakdowns far in advance. Vinyl DJs will find this familiar because quiet sections of tracks can be visually distinguished when looking at a vinyl record. This is a useful tool when planning your mixes on-the-fly.
10.7. Izenačevanje ritma in miksanje¶
Izenačevanje ritma je postopek prilagajanja hitrosti predvajanja skladbe, tako da ustreza tempu druge skladbe. Izenačevanje ritma vsebuje tudi prilagajanje faze ritma v skladbi, tako da so te poravnane z dobami v drugi skladbi. Izenačevanje tempa in poranava dob sta dve stvari, ki jih mora didžej opraviti, da bi izenačil ritem.
Mixxx can match the tempo and align the beats for you but this requires an accurately detected BPM value and a correct beat grid for both tracks. To enable this feature, hit the SYNC button. To beatmatch manually, the tempo of the two tracks must be synchronized by adjusting the playback rate sliders. You can adjust the phase of the beats by right-clicking and dragging on either waveform display to temporarily speed up or slow down one of the tracks until the beats are aligned. The temporary pitch bend buttons can also be used to momentarily adjust the playback rate, allowing you to “shuffle” the beats in a track forwards or backwards, so they can be aligned with another track. See the chapter Kontrole za sinhronizacijo in določanje hitrosti.
Two tracks are beatmatched once their tempos are matched and their beats beats are aligned. A “perfect” beatmatch is nearly impossible - there will always be a tiny difference in the playback rates. A keen DJ will keep his or her ears open and listen for the beats drifting out of alignment. This has a distinct “double bass kick” sound which is often preceded by the kick weakening in intensity as the two kicks drift out of phase. When this happens, the beats can be realigned by simply tapping one of the temporary pitch bend buttons a few times in the appropriate direction.
10.8. Headphone Cueing¶
Headphone cueing is a technique DJs use to listen to the next track they want to play in their headphones before playing it on the main speakers. Headphone cueing is useful because it allows a DJ to beatmatch the next track in their headphones before bringing it into their mix by sliding the crossfader.
Mixxx allows a DJ to route audio from either deck to their headphones by toggling either of the Headphone buttons in the mixer section of Mixxx’s interface. See the chapter The Mixer Section.
10.9. BPM and Beat Detection¶
Previous versions of Mixxx were able to detect BPM values but unable to determine where the beats are. Consequently, the beat grids often looked unaligned. The DJ had to adjust the beat grid manually in oder to make use of auto-beatmatching via SYNC button.
Spremenjeno v verziji 1.11: Mixxx comes with a new ultra-precise BPM and beat detector.
The beat grid is adjusted after track analysis is finished. Manual adjustments are redundant in many cases because Mixxx knows where the beats are.
10.9.1. Analyser Settings¶
BPM and beat detection is a complex operation. Depending on your computer and the track’s bitrate and duration this may take some time. By default Mixxx analyzes the complete track. To accelerate beat detection on slower computers, a “Fast Analysis” option is available. If enabled, the BPM is computed by analyzing the first minute of the track. In most cases this does not affect the beat detection negatively because most of today’s dance music is written in a 4/4 signature with a fixed tempo.
The table below summarizes the beat detection settings:
Enable Fast Analysis
If enabled, BPM detection results from the first minute of audio.
Assume constant tempo
If enabled, Mixxx assumes that the distances between the beats are constant. If disabled, the raw beat grid obtained by the analyzer is presented. The latter is appropriate for tracks with variable tempo.
Enable Offset Correction
Prevents beat markers from being placed incorrectly.
Re-analyze beats when settings change or beat detection data is outdated
If enabled, Mixxx over-writes old beat grids from Mixxx before v1.11. Moreover, it will re-analyze the BPM if your beat detection preferences change or BPM data from 3rd party programs are present.
10.9.2. Correcting Beat Grids¶
There may be situations where BPM and beat detection do not result in a proper beat grid.
Typically, the detected BPM is correct but the analyzer has failed to detect the location of the first beat. Consequently, the beat markers are shifted, i.e. the beat markers are always a fixed distance from the true beat. To adjust the beat grid, cue the track before a real beat and click the Beat-grid Adjust button in the Mreža gumbov z opcijami predvajalnika.
If the detected BPM is not accurate, the corresponding beat grid will also be inaccurate. A deviation of 0.02 BPM units from the correct BPM will cause beatgrid alignment issues on long tracks (e.g. a club mix). If this happens, your beatgrid may look aligned for the few minutes but you will notice a slight drift as the song goes on. Finding the correct BPM is easy in many cases - just follow the note below.
If the detected BPM value is not sufficiently accurate but very close to an integer value, try to set the BPM value manually to the integer.
10.10. Recording your Mix¶
With the integrated recording feature you can record your mix as an audio file and listen to it later, distribute it as Podcast or burn it to CD. Mixxx records the master output - the audio you hear from the speakers including the microphone.
