10. Didžejanje s programom Mixxx¶
Mixxx je bil ustvarjen za enostavno učenje tako za novince, kot tudi izkušene didžeje.
Ta del priročnika podaja smernice za uporabo funkcionalnosti programa Mixxx pri ustvarjanju lastnih miksov.
10.1. Pravilno nastavljanje nivojev (določitev ojačitev)¶
Pravilna nastavitev nivojev, ki je poznana tudi kot Gain Staging, je bistvena za zagotavljanje najboljše kakovosti zvoka opreme, ki jo uporabljate. V vsaki povezavi v vaši verigi signala, od Mixxx ojačitev kanala pa do ojačevalca, morajo biti nivoji krepko preko praga šuma, a še vedno pod maksimalnim nivojem, preko katerega začne signal prebijati. Merilci nivojev bi morali iti večinoma do vrhnjega dela zelenega področja. Merilec nivoja prikazan na levi strani prikazuje, kje bi morali biti merilci v povprečju ob na najbolj glasnih delih skladb. Povprečni nivo naj ne bi bil v rumenem delu. Rumeni del uporabite, da dopustite prostor na vrhu, ki omogoča da bolj glasni deli ne prebijajo. Najbolj glasni deli (vrhovi) naj za kratek čas uidejo v rumen del.
Valovna oblika z dobrimi nivoji. Bodite pozorni na to, da so primeri valovnih oblik v tem razdelku bili ustvarjeni s prilagajanjem prikaza ojačitve v prikazovalniku valovne oblike, da bi bolje prikazali koncept dela. Prilagajnje prikaza ojačitve sicer ne vpliva na nivo signala zvoka.¶
Če je merilec signala v rdečem področju, signal prebija in je potrebno znižati ojačitev. Nekatere naprave nimajo merilca nivojev, temveč le LED lućko, ki zasveti, ko signal prebija. Prebijanje pomeni, da se vrhovi valovne oblike stisnejo ali porežejo, ker je naprava dosegla največjo stopnjo ojačitve signala, ki jo zmore. To popači zvok na neprijeten način in lahko opremo poškoduje, saj jo poganjamo z več moči, kot jo lahko prenese. Jačanje signala preko točke, kjer se začne prebijanje (še bolj v rdečo), bo še bolj opačilo zvok. Če želite narediti zvok bolj glasen po tem, ko so vsi členi v verigi signala na maksimumu, uporabite več zvočnikov ali bolj občutljive zvočnike, ki bolj učinkovito pretvarjajo elektirčno energijo v akustično.
Prebijanje valovne oblike¶
Po drugi strani signal ne sme biti prenizek. Razlog temu je dejstvo, da vsaka zvočna naprava ustvarja tudi nekaj šuma, ki mu pravimo prag šuma. Poleg tega analogni signali pobirajo šum, ko potujejo po žicah. Signal, ki ga je izmeril merilnik na levi, je precej blizu pragu šuma. Vendar - vsakič ko ojačimo signal iz predhodne naprave v verigi signala, se ojačita tako signal, kot tudi šum. Na primer, če je vaša zvočna karta utišana in ojačite signal na mešalni mizi, da bi ga dvignili, je razmerje med signalom in šumom zvočne (SNR) kartice majhno in bo miksre ojačal tako signal, kot tudi šum, vključno s šumom, ki ga povzroči žica. Končni rezultat bo imel več šuma, kot bi ga imel, če bi dvignili izhod zvočne kartice in signala ne bi bilo potrebno ojačiti na mešalni mizi.
10.2. Izenačevanje ritma in miksanje¶
Beatmatching is the process of adjusting the playback rate of a track so that it matches the tempo of another track. Beatmatching also involves adjusting the phase of the beats in a track so that they are aligned with the beats in the other track. Matching the tempo and aligning the beats are the two things a DJ must do to beatmatch.
Mixxx lahko izenači tempo in poravna ritem namesto vas, a za to potrebuje za obe skladbi natačno prepoznan BPM in pravilni ritmični mreži za. Ta funkcija se vključi z gumbom SYNC. Za ročno izenačevanje ritma je potrebno tempo obeh skladb sinhronizirati z uporabo drsnika hitrosti. Fazo ritma lahko prilaogdite tako da desno kliknete in vlečete po poljubnem prikazovalniku valovne oblike in tako začasno pospešite ali upočasnite eno od skladb, dokler obe nista poravnani. Za trenutno prilagajanje hitrosti so na voljo tudi gumbi za začasno pregibanje višine, ki omogočajo “prerazporejanje” dob naoprej ali nazaj, tako da jih izenačimo z drugo skladbo. Glej poglavje Kontrole za sinhronizacijo in določanje hitrosti.
Dve skladbi sta ritmično izenačeni, kadar iamta enak tempo in so dobe poravnane. “Perfektno” izenačen ritem je skorajda nemogoče doseči, ker bodo vedno obstajale majhne razlike v hitrosti predvajanja. Vešč didžej bo imel našpičena ušesa in bo poslušal, kdaj se ritma začneta razhajati. V tem primeru se pojavi značilni zvok “dvojnega bas bobna”, pred katerim se pogosto pojavi manjašanje jakosti basa, ki je posledica faznega zamika. Ko se to zgodi, se lahko ritma poravnata z nekaj pritiski na gumb za pregibanje višine.
10.3. Master Sync¶
Novo v verziji 2.0.
Master Sync is an intelligent assistant that allows you to leave the beatmatching to Mixxx so you can focus on track selection, effects manipulation, looping, 4 deck mixing, and other advanced DJing techniques.
To activate Master Sync on a deck, push and hold (or click and hold) the SYNC button. You’ll know Master Sync is on because the sync button will remain lit. Changing the rate of any deck that has Sync lit will change the rates of all other decks that also have the Sync button lit. There is no need to set specific decks to be a master or followers. You can play, stop, eject, load, and queue any track with master sync and it won’t interrupt the playback of the other decks. However, changing the rate of a stopped deck will change the rate of playing decks.
Master Sync will also notice if one of your tracks is double the BPM of another track and match them correctly. So if you want to mix a 140 BPM drum & bass track with a 70 bpm dubstep track, Master Sync will make sure they are lined up properly.
Nasvet
Usually, Master Sync will only make sure the rate sliders are set correctly. If you also want to make sure your beats are perfectly in sync, turn on the QUANTIZE button. When activated, Quantize will ensure that the beats are perfectly lined up as well.
10.4. Harmonično miksanje¶
Harmonic mixing is a technique to mix songs with matching melodies and harmonies. To learn more about harmonic mixing you might want to check out the mixshare site.
Mixxx has two features to help you with harmonic mixing. The first is a key lock. When it is active changing the speed of a track won’t affect the key. To enable key lock, click the key lock button in the Mreža gumbov z opcijami predvajalnika. The second is that Mixxx can automatically detect the key of a track and will display it in the library and the decks. The notation which is used to display a key can be changed in Key Detection Preferences.
10.5. Using Effects¶
Novo v verziji 2.0.
Mixxx comes with a set of native effects.
10.5.1. Flanger¶
The Flanger is simple modulation effect, created by taking the input signal and mixing it with a delayed, pitch modulated copy of itself.
- Depth
Controls the intensity of the effect.
- Delay
Sets the value for the delay length.
- Period
Controls the speed of the effect.
10.5.2. BitCrusher¶
The BitCrusher is an effect that adds quantization noise to the signal by the reduction of the resolution or bandwidth of the samples.
- Bit Depth
Adjusts the bit depth of the samples.
- Downsampling
Adjusts the sample rate to which the signal is downsampled.
10.5.3. Filter¶
The filter changes the tone of the music by allowing only high or low frequencies to pass through.
- LPF
Corner frequency ratio of the low pass filter.
- Q
Resonance of the filters, default = Flat top.
- HPF
Corner frequency ratio of the high pass filter.
10.5.4. Reverb¶
This is a port of the GPL’ed CAPS Reverb plugin, which has the following description: This is based on some of the famous Stanford CCRMA reverbs (NRev, KipRev) all based on the Chowning/Moorer/Schroeder reverberators, which use networks of simple allpass and comb delay filters.
- Bandwidth
Higher bandwidth values cause more bright (high-frequency) tones to be included.
- Damping
Higher damping values cause reverberations to die out more quickly.
Opomba
This effect is not available in the Mac App Store version of Mixxx.
10.5.5. Echo¶
Simple Echo with pingpong
- Send
How much of the signal to send into the delay buffer.
- Delay
Delay time in seconds.
- Feedback
Amount the echo fades each time it loops.
- PingPong
As the ping-pong amount increases, increasing amounts of the echoed signal is bounced between the left and right speakers.
10.6. Snemanje miksa¶
With the integrated recording feature you can record your mix as an audio file and listen to it later, distribute it as a Podcast or burn it to CD. Mixxx records the master output - the audio you hear from the speakers including the microphone.
Mixxx zbirka - Ogled posnetkov¶
Mixxx can record your mix in various audio formats and quality settings. You can
split your recordings, generate cue files, choose a custom
recording directory and even set your own metadata. By default, Mixxx
saves your recordings as lossless wav files to a
Mixxx/Recordings sub-folder in the Mixxx music directory. Before you
start recording, we recommend that you adjust the settings in
.
Če kliknete na ikono „Posnetki“ na stranskem panoju v Mixxx zbirki, pano na desni prikaže vsebino našega direktorija s posnetki. Novi posnetki se bodo shranili v ta direktorij, kot tudi CUE datoteke, če jih potrdite v možnostih.
Nasvet
Snemanje miksov za kasnejše kritično poslušanje je odlično orodje za izboljšanje lastnih didižejevskih tehnik. V pomoč je tudi, če svoje mikse pošljete drugim didžejem, da vam podajo mnenje.
10.6.1. Posnemite svoj miks na disk¶
Novo v verziji 2.0: Displays the duration of the recording.
Kliknite na ikono „Posnetki“ v stranskem panoju, da bi preklopili v pogled Posnetki.
Kliknite na gumb Začni snemati`ali kliknite na :menuselection:`Možnosti –> Snemaj miks V meniju na vrhu okna programa Mixxx.
The display above the track table shows how much data has already been recorded, as well as the duration of the recording.
Izvedite svoj miks
Kliknite na gumb Ustvai snemanje, da zaustavite snemanje, ko je miksanje končano.
Nasvet
You can instantly play your recording as a track in Mixxx. Simply drag-and-drop the track to a deck.
10.7. Using Auto DJ For Automatic Mixing¶
Mixxx zbirka - Samodejni DJ pogled¶
Novo v verziji 2.0: Add random tracks from Auto DJ track sources
Samodejni DJ omogoča samodejno nalaganje skladb iz seznama predvajanja samodejnega didžeja, ko se trenutna skladba že skoraj konča in navzkrižni prehod na njo. Glej Auto DJ - Automate your mix.
10.7.1. Nalaganje skladb v Auto DJ¶
Za samodejno predvajanje skladb, morajo biti te najprej naložene v Auto DH seznam predvajanja. Privzeto je ta seznam prazen.
Mixxx zbirka - Dodajanje seznama predvajanja v Samodejni DJ¶
Obstaja več načinov za nalaganje skladb v Auto Dj seznam predvajanja.
Izberite eno ali več skladb iz zbirke, seznama predvajanja ali zaboja in ga povlecite na ikono Samodejni DJ na levi strani.
Izberite običajen seznam predvajanja ali zaboj, desno kliknite nanji in iz miškinega menija izberite Dodaj v Auto DJ. To bo dodalo skladbo v Auto DJ zaporedje.
Medtem, ko ste v Samodejni DJ prikazu zbirke, povlecite skladbe iz zunanjega upravljalnika datotek na ikono Samodejni DJ v stranskem panoju ali na Samodejni Dj seznam skladb na desni.
10.7.2. Using Auto DJ crates¶
Instead of inserting the contents of the crates directly into the Auto DJ playlist, Auto DJ crates are associated crates that become a source of random track selections.
Add a crate to the Auto DJ track sources: Expand the Auto DJ item in the sidebar, and right-click on the Crates sub-item. Select one of the existing crates from the list. This makes the content of the crate available for random selection into the Auto DJ queue for automatic mixing. The name of the crate is now listed as sub-item below.
If you do not have any crates available for selection in the list, go and create a crate first and add some tracks, see Crates - Organizing tracks into collections.
Manually add tracks from track sources to Auto DJ: Click the Auto DJ item in the sidebar and switch to the Auto DJ view of the library. Click the Add random button to add one track at the time from Auto DJ track sources to the bottom of the Auto DJ playlist.
Opomba
If you did not set any crates as an Auto DJ track source, clicking the Add Random button will add a randomly selected track from the whole library instead.
Automatically add tracks from track sources to Auto DJ: Mixxx can randomly add tracks to the Auto DJ playlist from track sources as soon as a specified minimum number of tracks remain. Select . Set to change the minimum number of tracks after which random tracks may be added.
Opomba
If you did not set any crates as an Auto DJ track source, tracks are selected from the whole library instead.
Remove a crate from the Auto DJ track sources: Expand the Auto DJ item in the sidebar, and right-click on one of the crates listed below the Crates sub-item. Select Remove Crate as Track Source to remove the crate from the Auto DJ track sources.
10.7.3. Predvajanje skladb z Auto DJ¶
Sedaj, ko ste naložili skladbe v Auto DJ seznam predvajanja, lahko aktivirate Auto DJ na tak način:
Kliknite na ikono ‚Samodejni DJ ‚ v stranskem panoju, da preklopite na Samodejni DJ prikaz zbirke.
Kliknite na gumb Vklopi Auto DJ.
Prva skladba iz vašega seznama se bo naložila v predvajalnik in predvajanje se bo začelo.
Mixxx bo samodejno miksla skladbe, dokler AutoDJ seznam predvajanja ne bo prazen.
Kliknite na gumb Izklopi Auto DJ, da zaustavite samodejno miksanje skladb
Nasvet
You can add a track to the end of the Auto DJ playlist once it is played instead of removing it. Set .
