Microphone xaiv

Tus yuam sij rau lub kaw lus microphone zoo yog txhawm rau teeb tsa lub suab kom raug raws li lub microphone thiab lub suab nrov ntawm chav uas koj kaw. Hauv cov ntsiab lus no, tus qauv coj ntawm lub microphone yuav txiav txim siab.

Nws yog feem ntau txiav txim siab tias qhov twg sab hauv acoustics tsis yog qhov zoo dua, peb siv cov pob microphones, uas tsis tshua muaj suab nrov ntawm sab thiab nraub qaum. Txawm li cas los xij, ib tus yuav tsum nco ntsoov txog lawv qhov sib thooj, i.e. teeb tsa suab qis thaum lub microphone ze rau lub suab. Yog li ntawd, kev tso microphone yuav xav tau qee qhov kev sim hauv qhov no.

Yog tias peb muaj chav nrog acoustics uas peb xav kom suav nrog hauv peb qhov kev txhaj tshuaj, lub microphones puag ncig uas yuav luag tib yam rhiab heev rau cov teeb liab los ntawm txhua qhov kev qhia ua haujlwm zoo tshaj plaws. Yim-note microphones, ntawm qhov tod tes, tsis quav ntsej tag nrho cov suab ntawm sab, tsuas yog teb cov suab los ntawm sab xub ntiag thiab sab nraub qaum, ua rau lawv tsim nyog rau cov chav uas tsuas yog ib feem ntawm chav tsev acoustics yog qhov zoo ntawm lub suab.

Kev nyeem ntawv yam ntxwv

Siv cov lus teb zaus thiab kev taw qhia ntawm AKG C-414 condenser microphone ua piv txwv, tam sim no peb pom yuav ua li cas nyeem cov duab no. Lawv tseem ceeb heev rau peb vim lawv tso cai rau peb los kwv yees tus cwj pwm ntawm lub microphone hauv ib qho xwm txheej.

Cov yam ntxwv qhia tau hais tias theem teeb liab ntawm lub microphone tso zis nyob ntawm qhov zaus ntawm lub teeb liab acoustic. Saib ntawm nws, peb pom tias nyob rau hauv qhov ntau txog li 2 kHz nws yog heev txawm (ntsuab, xiav thiab dub nkhaus qhia cov yam ntxwv tom qab tig rau lub low-pass lim ntawm txawv frequencies). Lub microphone khaws cov zaus me ntsis hauv 5-6kHz ntau thiab qhia txog kev txo qis hauv kev ua haujlwm siab tshaj 15kHz.

Cov yam ntxwv directional, i.e. ib hom duab ntawm microphone rhiab heev, pom los ntawm tus noog qhov muag pom. Sab laug ntawm daim duab qhia tau hais tias tus cwj pwm coj mus rau zaus ntawm 125 txog 1000 Hz, thiab tib yam rau qhov ntau ntawm 2 txhiab mus rau sab xis. mus txog 16k Hz (cov yam ntxwv no feem ntau yog symmetrical, yog li tsis tas yuav sawv cev rau lub voj voog thib ob). Qhov tsawg zaus, qhov ntau puag ncig tus qauv ua. Raws li qhov zaus nce, tus yam ntxwv nqaim thiab rhiab heev rau cov teeb liab los ntawm sab thiab tom qab poob qis.

Dab tsi sab hauv, xws li lub microphone

Kev siv lub npe hu ua Acoustic microphone shields tsis cuam tshuam rau lub suab ntawm lub microphone ntau npaum li nws tso cai kom txo cov theem ntawm cov teeb liab cuam tshuam los ntawm cov phab ntsa hauv chav, thiab yog li pab kom tsis txhob muaj suab nrov ntawm sab hauv ntawm me ntsis. txaus siab rau qhov kev hwm no.

Yog tias koj lub studio muaj ntau cov ntaub ntawv dampening - hnyav curtains, ntaub pua plag, fluffy lub rooj zaum, thiab lwm yam - koj yuav xaus nrog lub suab qhuav thiab muffled. Qhov no tsis txhais hais tias cov chav zoo li no tsis haum rau kev kaw, piv txwv li, cov suab. Muaj ntau tus neeg tsim khoom uas txhob txwm tshaj tawm lawv lub suab hauv cov chav zoo li no, tawm hauv lawv tus kheej los tsim qhov chaw xav tau siv cov teebmeem digital processors. Txawm li cas los xij, nws tsim nyog paub tias qhov chaw no tuaj yeem ua rau muaj kev cuam tshuam loj rau kev ua haujlwm ntawm cov neeg hu nkauj, uas, ntawm chav kawm, tsis zoo rau kev kaw lus zoo. Cov neeg hu nkauj nyiam xav tias "me ntsis cua" nyob ib puag ncig lawv, uas yog vim li cas qee tus neeg hu nkauj nyiam hu nkauj hauv chav loj.

Qee lub microphones zoo dua rau cov ntawv thov tshwj xeeb tshaj li lwm tus, yog li nws tsim nyog xav txog seb lub microphones siv ua ntej koj pib sau. Cov yam ntxwv yuav tsum tau coj mus rau hauv tus account suav nrog bandwidth thiab sonic yam ntxwv ntawm lub suab nrov, nrog rau qib siab tshaj plaws uas lawv tsim. Qee zaum qhov tseem ceeb ntawm kev lag luam kuj tseem nyob ntawm ceg txheem ntseeg - koj yuav tsum tsis txhob siv cov microphones kim rau cov suab paj nruag uas pheej yig dua thiab yooj yim nkag tau yooj yim analogue txaus.

Vocals thiab guitars

Thaum kaw cov suab, feem ntau cov kws tshaj lij suab nyiam cov diaphragm condenser microphones loj nrog lub raum teb. Ribbon microphones tau siv ntau dua rau lub hom phiaj no. Nws tseem tsim nyog sim saib seb koj lub suab yuav zoo li cas nrog lub microphone tsis tu ncua xws li Shure SM57 / SM58. Cov yav tas tuaj yeem siv tau rau hauv cov xwm txheej studio uas tau kaw suab nrov thiab hnyav, xws li hauv pob zeb, hlau lossis suab paj nruag punk.

Nyob rau hauv cov ntaub ntawv ntawm guitar amp kaw, dynamic microphones nyob deb ntawm qhov zoo tshaj plaws kev daws teeb meem, txawm hais tias ib co suab engineers siv ob qho tib si me me diaphragm condenser qauv thiab classic loj diaphragm microphones.

Raws li nyob rau hauv cov ntaub ntawv ntawm lub suab, ribbon microphones tau siv ntau dua rau qee lub sijhawm tam sim no, uas, tsis muaj exaggerating qhov tshwm sim ntawm lub siab zaus, tso cai rau koj ua kom tau txais kev txhaj tshuaj zoo hauv cov ntses bass thaj tsam thiab nruab nrab. Nyob rau hauv cov ntaub ntawv ntawm ribbon microphone, nws txoj hauj lwm raug yog qhov tseem ceeb - qhov tseeb yog tias nws tsis tuaj yeem muab tso rau tib lub dav hlau ntawm lub suab nrov, vim qhov no tuaj yeem ua rau muaj kev cuam tshuam tsawg zaus, thiab hauv qhov xwm txheej hnyav txawm tias ua rau lub ribbon microphones puas. (microphones ntawm hom no yog rhiab heev rau lub dav hlau ntawm cov neeg hais lus). ncaj hits).

Kev kaw cov ntses bass thaj tsam feem ntau yog ua tiav ob txoj hauv kev - kab-hauv, piv txwv li ncaj qha los ntawm lub cuab yeej, thiab siv lub microphone txuas nrog lub suab nrov, thaum loj-diaphragm condenser microphones thiab dynamic microphones kuj feem ntau siv rau microphone kaw. Nyob rau hauv rooj plaub tom kawg, cov neeg tsim khoom nyiam siv mics tsim rau ncaws nruas, uas nws cov yam ntxwv kuj ua haujlwm zoo rau kev kaw cov ntses bass thaj tsam.

Acoustic guitar

AKG C414 series microphones yog qee qhov ntau yam microphones hauv khw. Lawv muaj tsib tus yam ntxwv hloov pauv hloov tau.

Ob qho tib si acoustic guitar thiab lwm yam twj paj nruag yog ib qho zoo nkauj tshaj plaws thiab tib lub sij hawm qhov nyuaj tshaj plaws los sau cov suab paj nruag. Nyob rau hauv lawv cov ntaub ntawv, dynamic mics tsis ua hauj lwm raws nraim, tab sis cov ntaub ntawv nrog condenser mics - ob qho tib si loj thiab me diaphragms - feem ntau ua hauj lwm zoo. Muaj ib pab pawg neeg ua suab nrov uas siv ribbon mics rau cov kev sib tham no, tab sis tsis yog txhua tus ua tau zoo los tuav cov xwm txheej no. Rau qhov zoo tshaj plaws sounding guitar, ob lub microphones yuav tsum tau siv - ib tug nrog ib tug loj diaphragm uas yuav mounted ib tug tej yam kev ncua deb ntawm lub twj paj nruag kom tsis txhob muaj suab bass thaj tsam ntau dhau los ntawm lub suab ntawm lub thawv, thiab ib tug me me diaphragm uas feem ntau yog tsom rau. lub kaum ob fret ntawm guitar.

Kev xyaum qhia tau hais tias nyob rau hauv tsev studio tej yam kev mob, me me diaphragm microphones yog qhov zoo tshaj plaws tov, raws li lawv muab txaus clarity thiab suab ceev. Txoj hauj lwm kuj tsis muaj teeb meem li loj diaphragm mics. Qhov tom kawg, ntawm qhov tsis sib xws, yog qhov zoo tshaj plaws nyob rau hauv kev tshaj lij studio, hauv chav nrog kev pom zoo acoustics. Ib qho acoustic guitar kaw li no feem ntau yog suab meej heev, nrog rau qhov yog qhov tob thiab txhais.

cua tshuab

Thaum kaw cov twj paj nruag cua, ribbon microphone yog qhov nyiam tshaj plaws ntawm cov suab engineers feem ntau. Txij li thaum cov lus teb yog qhov tseem ceeb hauv lub suab ntawm cov cuab yeej no, nws cov yam ntxwv octal directional thiab ib lub suab tshwj xeeb uas tsis exaggerate siab tones ua haujlwm zoo heev ntawm no. Cov diaphragm condenser microphones loj tuaj yeem siv tau, tab sis cov qauv nrog cov lus teb octal (switchable microphones yog qhov feem ntau) yuav tsum tau xaiv. Tube mics ua haujlwm zoo hauv cov xwm txheej no.

piano

ib qho cuab yeej tsis tshua tau kaw hauv tsev studio. Nws yog ib qho tsim nyog paub tias nws txoj hauv kev kom raug yog ib qho kev kos duab tiag tiag, feem ntau yog los ntawm thaj chaw loj ntawm lub suab tsim, qhov dav ntawm qhov ntau thiab qhov muaj zog. Rau kev kaw suab piano, me me thiab loj diaphragm condenser microphones feem ntau yog siv, thiab ob lub omnidirectional microphones, me ntsis deb ntawm qhov ntsuas, nrog lub hau, muab cov txiaj ntsig zoo. Qhov xwm txheej, txawm li cas los xij, yog qhov zoo acoustics ntawm chav kaw. Lub hlis tom ntej, peb yuav saib txoj hauv kev los sau cov suab paj nruag ntawm lub microphone. Lub ntsiab lus no yog ib qho kev sib tham tshaj plaws ntawm kev ua haujlwm studio.
