Ua tsaug rau kev sib txuas lus loj, ib qho xov xwm tuaj yeem nthuav tawm sai sai hauv Is Taws Nem thiab xov xwm. Ntxiv mus, tsuas yog ib lub koom haum xov xwm xwb yog qhov chaw ntawm cov ntaub ntawv, thaum tus so tsuas yog luam tawm thiab xa tawm ntxiv, luam tawm cov xov xwm. Ntawm cov chaw xov xwm, koj tuaj yeem pom cov ntawv txuas mus rau lwm cov ntaub ntawv xov xwm nrog tib cov ntaub ntawv. Qhov no yog lub hauv paus ntsiab lus ntawm reverberation los yog ncha, tsuas yog nyob rau hauv lub tshav pob ntawm kev sib txuas lus.

Lub ntsiab lus ntawm reverb

lo lus no muaj nyob hauv physics thiab cuam tshuam nrog ntu ntawm acoustics. Qhov no yog cov nyhuv ntawm recoil thiab xav txog ntawm lub suab nthwv dej ntawm txhua qhov teeb meem, thiab nws rov qab mus rau qhov chaw. Qhov no tshwm sim nyob rau hauv tej yam ntuj tso acoustic ib puag ncig - nyob rau hauv lub chaw ntau pob, nyob rau hauv ib tug loj chav tsev, chav tsev, thiab txawm lub studio. Tus neeg mloog nkag siab nrog nws lub pob ntseg tsis yog lub hauv paus ntawm lub suab xwb, tab sis kuj nws qhov kev xav ntawm qhov chaw.

Hauv physics, ob hom kev rov qab los paub txog: ntuj thiab dag, thaum nrog kev pab cuam ntawm kev siv tshuab thiab kev hloov kho ntawm cov suab nrov ntxiv yog tsim. Lub suab cuam tshuam los ntawm phab ntsa maj mamsubsides tom qab lub suab qhov chaw nres suab. Tib neeg tsuas hnov echoes lossis kev xav ntawm lub suab sib txawv.

Artificial reflector

A reverb yog ib yam khoom tshwj xeeb uas ua rau kom muaj zog ntawm kev rov qab los ntawm lub suab nthwv dej los ntawm cov phab ntsa los yog tsim cov nyhuv zoo li no nyob rau hauv qhov chaw uas tsis muaj lub suab nrov. Hauv xyoo 70s, daim kab xev reverb tau nrov. Los ntawm kev tsim, nws yog me ntsis reminiscent ntawm ib daim kab xev recorder ntawm lub sij hawm ntawd, nrog reels.

Thaum lub suab pib ua si, lub reverb nyeem nws tawm nrog lub taub hau kaw thiab xa mus rau daim kab xev. Lub taub hau playback ces nyeem cov suab ntawm daim kab xev. Tus naj npawb ntawm lub taub hau qhia tias pes tsawg zaus lub suab rov tsim dua. Qee cov qauv muaj txog li kaum ntawm cov taub hau no thiab ntau dua. Lub cav ntawm lub suab nrov ntawm txhua lub teeb liab nrog txhua lub taub hau tau ntsiag to, uas tsim cov nyhuv ntawm lub suab nrov nrov.

Cov txiaj ntsig zoo ntawm reverb tau ua tiav los ntawm kev ceev ntawm daim kab xev (kwv yees li 38 centimeters ib ob) thiab qhov tsawg kawg nkaus nyob deb ntawm lub taub hau playback.

A reverb tsis yog lub tshuab luam ntawv suab, nws yog ib qho cuab yeej uas muaj peev xwm rov tsim cov nplai ntawm lub suab nrov. Txawm li cas los xij, txawm tias nyob rau hnub ntawd, cov kab xev kaw tau ua haujlwm hauv ob hom: lawv tsim cov ncha thiab cov suab nrov dua.

Reverb yam ntxwv

Ntawm no yog cov yam ntxwv tseem ceeb ntawm reverb thiab cov qauv nws yuav tsum ua tau raws li:

  1. Reaction ntawm impulses. Thaum lub suab nkag mus rau lub taub hau kawua ntej nws tawm mus, luv luv pulsation tshwm sim. Lub sijhawm nruab nrab ntawm cov pulses yuav tsum tsis pub tshaj 0.05 vib nas this, txwv tsis pub tus mloog yuav pom cov ncha raws li cov suab sib cais rov ua dua ib zaug. Qhov no yog qhov tsis xws luag.
  2. Reverb time. Qhov no yog lub sij hawm thaum lub voltage ntawm lub suab ntog tawm tom qab lub ntsiab lub suab ntawm lub input nres. Ntawm qhov tso zis, ib qho me me reverb txo lub suab lub zog mus rau 60 dB los ntawm thawj lub suab. Lub voltage yuav tsum poob, raws li nws tshwm sim nyob rau hauv ib tug natural acoustic ib puag ncig. Cov nyhuv no tuaj yeem hloov kho nws tus kheej los ntawm kev hloov lub sijhawm reverb thiab ntim. Kho tus nqi lwj ntawm lub teeb liab lossis hloov qhov sib piv ntawm lub suab ncaj qha thiab ncha.
  3. Kev sib kis. Voltage amplitude ntawm lub suab nkag thiab tawm. Nyob rau hauv ib chav loj, lub amplitude peaks ntawm daim duab yog teem irregularly nrog ib tug ncua sij hawm mus txog rau 4 Hz thiab dips ntawm 25 dB los yog ntau tshaj. Yog li ntawd, txhawm rau kom lub suab reverb tuaj yeem simulate acoustic ncha nyob rau hauv ib chav loj zoo, qhov ceev thiab qhov ntev ntawm cov zaus peaks yuav tsum phim cov ntsuas no.

Dab tsi yog qhov system

Reverbs muaj ntau lub tshuab ua haujlwm:

  • kab xev. Lub suab playback yog kaw rau ntawm daim kab xev.
  • Caij nplooj ntoos hlav. Lawv yog cov me me, ua haujlwm ntawm lub hauv paus ntsiab lus ntawm lub suab qeeb thiab kev vibrations ntawm lub caij nplooj ntoos hlav.
  • Digital reverb. Lub suab tseem ceeb yog pub rau lub modulator ntawm lub transceiver, uas ncua lub teeb liab thiab tsim cov nyhuv ncha. Digital signal processing muab nws ib qho tshwj xeebcoloration.

Nws tsim nyog them nqi rau lub caij nplooj ntoo hlav, vim tias cov cuab yeej zoo li no pheej yig dua, tus qauv tsim tsis nyuaj, thiab koj tuaj yeem ua qhov reverb nrog koj tus kheej tes.

Lub teeb liab nkag mus rau hauv lub cuab yeej yog nthuav tawm los ntawm lub cuab yeej tshwj xeeb, hloov dua siab tshiab thiab vibrates cov khoom txav. Lub caij nplooj ntoos hlav txuas rau lub caij txav no, uas, nyob ntawm qhov ntev thiab cov coils, txiav txim siab ntev npaum li cas cov teeb liab tuaj txog yuav ncav cuag tus txais, thiab lub suab yuav ntev npaum li cas.

Cov qauv twg yuav tsum tau ua

Cia peb xav txog yam uas koj yuav tsum tau xav txog thaum ua tus reverb tom tsev.

Yog li, qhov zaus ntawm kev rov ua dua ntawm cov peaks hauv qhov bandwidth ntau ntawm 100 Hz yuav tsum tsis pub tsawg tshaj 15 thiab tsis ntau tshaj 20. Qhov nruab nrab nruab nrab ntawm cov teeb liab yog 0.025 vib nas this. Kev khiav hauj lwm zaus ntawm 150 mus rau 3000 Hz. Lub suab vibration lub sij hawm ntawm qis zaus - tsis pub ntau tshaj 4 vib nas this, nyob rau sab sauv frequencies - tsis ntau tshaj 2 vib nas this.

Ntxhais lub sij hawm ncha ntawm qhov tsawg zaus distors lub clarity ntawm lub suab. Nyob rau hauv lub caij nplooj ntoos hlav reverb, lub sij hawm ntawm high zaus yog luv heev, tsis ntau tshaj 2 vib nas this, tab sis qhov tsawg zaus, lub sij hawm ntev dua, ncav cuag 8 vib nas this. Yog li ntawd, peb yuav tsum tau nruab ib lub damper nyob rau hauv peb reverb, uas yuav txo tau lub sij hawm ntawm cov teeb liab ntawm tsawg zaus.

Yuav ua li cas xam qhov ntev thiab coils ntawm lub caij nplooj ntoos hlav

Lub caij nplooj ntoos hlav yog lub tshuab lim uas tso cai rau lub suab qis dhau mus. Yuav siv tausteel hlau lossis piano hlua nrog txoj kab uas hla ntawm 0.2-0.4 hli. Coiling yog ua tiav ntawm lub tshuab dhos kom cov lem ntawm tib txoj kab uas hla. Qhov ncua sij hawm kab yog 3-4 kHz, thiab txoj kab uas hla yog xam los ntawm cov qauv: nruab nrab ntawm txoj kab uas hla=yuav tsum tau txiav tawm zaus sib npaug ntawm txoj kab uas hla winding. Tus lej tig nyob ntawm lub suab ncua sij hawm.

hloov pauv thiab txheeb xyuas cov lej

Hloov lub converter, koj tuaj yeem siv lub tshuab nqus hlau nplaum lossis lub kauj nrog cov hlau nplaum. Lub kauj yog txuas rau phab ntsa ntawm lub reverb nrog ib daim hlau. Nyob nruab nrab ntawm ob lub hlau nplaum, lub transducer, nyob rau hauv lub zog ntawm lub suab yoj, oscillates lub kauj thiab lub caij nplooj ntoos hlav. Nws yog ib qho tsim nyog kom cov hlau hla dhau ntawm lub converter. Ib kawg ntawm nws nyob rau hauv lub converter clings rau lub ntsiab hlau, siv ib tug nuv txoj kev, thiab lwm yam kawg, 30 millimeters ntev, yog ib tug tuav. Yog tias siv txoj kab uas hla loj dua, ces qhov hla ntawm cov lem yuav tsum sib haum mus rau txoj kab uas hla ntawm cov hlau nws tus kheej, ntsuas hauv cubic millimeters. Lub receiver ntawm qhov kawg ua qhov opposite.

Tsis yog txhua tus tuaj yeem suav thiab ua txhua yam hauv tsev, vim tias kev kuaj xyuas lub sijhawm qeeb yog ua los ntawm cov cuab yeej tshwj xeeb. Tsis yog txhua tus muaj nws. Tab sis nrog me ntsis logic, ingenuity thiab ceev wit, reverb tsis yog npau suav xwb.

Nyob rau hauv cov txheej txheem artisanal, peb teeb tsa lub cuab yeej raws li hauv qab no: qhib lub tshuab hluav taws xob, ntsuas cov ntaub ntawv tso tawm nrog lub voltmeter. Peb maj mam hloov qhov zaus ntawm lub tshuab hluav taws xob kom txog rau thaum peb txiav txim siab lub caij nyoog ntawm cov peaks thiabzaus dips.

Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws

Cia peb tham luv luv txog qhov zoo tshaj plaws reverbs uas suav hais tias yog qhov zoo tshaj plaws hauv qeb hnub no.

Qhov chaw thib ib Bricasti Desing M7 yog cov khoom siv digital zoo tshaj plaws. Yav dhau los Lexicon engineers tau koom ua ke los tsim qhov zoo tshaj plaws hauv algorithmic suab reverb. Txawm hais tias nws kim heev, nws tseem nyob deb tsis tshua kim tshaj qhov sib piv saum toj-ntawm-tus-kab reverbs, raws li studio kaw cov tub txawg. Cov hom ntawv - 24 ntsis / 192 kHz, ntawm dual-core DSP platform. Ua raws li kev thov studio.

Fender '63 Reverb nyob rau hauv qhov chaw thib ob. Replica ntawm lub legendary 1963 reverb. Fender developers tau sim ua kom tiav cov cuab yeej raws li nws cov kev txwv. Phenol cov khoom siv hluav taws xob tau hloov nrog cov ntawv luam tawm, 6K6 teeb tau hloov nrog 6V6. Thawj-chav engineers tau nqis peev tag nrho lawv cov kev paub ntau xyoo hauv nws qhov kev tsim, yog li cov cuab yeej xav tau los ntawm ntau tus kws ntaus nkauj hauv ntiaj teb. Reverbs kuj tseem siv los txhim kho lub suab ntawm cov cuab yeej suab paj nruag nruab nrog cov khoom siv hluav taws xob, xws li hluav taws xob guitars.
