1. Suab teeb liab ua
Kev sib npaug:
Cov cim suab ntawm cov zaus sib txawv tuaj yeem hloov kho, thiab cov kab hluav taws xob tshwj xeeb tuaj yeem txhawb nqa lossis txo qis los txhim kho lub suab ntawm lub suab. Piv txwv li, ntxiv cov zaus qis tuaj yeem txhim kho lub suab thiab hnyav ntawm lub suab paj nruag; Boosting lub siab zaus tuaj yeem ua rau lub suab pom tseeb thiab ci dua.
Muaj peev xwm los kho tus kheej qhov sib npaug ntawm qhov sib txawv ntawm lub suab (xws li, suab, suab paj nruag, suab paj nruag tom qab, thiab lwm yam) los qhia txog lawv cov yam ntxwv lossis ua rau qhov tsis zoo.
Lim:
Low-pass filtering tshem tawm cov suab nrov nrov, ua rau lub suab smoother thiab softer. Hauv qee qhov xwm txheej, xws li kev tshaj tawm lub suab, suab nrov tom qab thiab cov khoom siv hluav taws xob hnyav tuaj yeem txo qis los txhim kho kev txawj ntse ntawm kev hais lus.
High-pass filtering yog siv los tshem tawm cov suab nrov tsawg zaus thiab cuam tshuam, xws li cua nrov thiab lub suab nrov ntawm lub tshuab, ua kom lub suab huv.
Bandpass filtering thiab bandstop filtering tuaj yeem xaiv cov teeb liab suab hauv qhov tshwj xeeb ntau zaus rau kev ua haujlwm lossis kev tawm tsam, thiab ua lub luag haujlwm tseem ceeb hauv kev tsim suab thiab kev tshuaj xyuas suab.
Compression thiab clipping:
Lub compression muaj nuj nqi tuaj yeem hloov kho qhov sib txawv ntawm lub suab teeb liab, kom lub suab nrov yog compressed thiab qhov me me tau txhim kho, kom lub suab teeb liab ruaj khov dua. Qhov no tseem ceeb heev hauv kev tshaj tawm xov xwm, kev tsim suab paj nruag, thiab lwm yam kev lag luam kom tsis txhob muaj qhov hloov pauv ntawm cov suab paj nruag thiab txhim kho kev mloog ntawm cov neeg mloog.
Lub luag haujlwm txwv txwv tsis pub lub suab teeb liab los ntawm overloaded thiab distorted, tiv thaiv tus neeg hais lus thiab lwm yam khoom siv suab los ntawm kev puas tsuaj. Thaum lub amplitude ntawm lub suab teeb liab tshaj qhov chaw pib, lub limiter cia li txwv nws mus rau ib tug ntau yam kev nyab xeeb.
2. Suab routing thiab faib
Input thiab output routing:
Lub tshuab hluav taws xob digital tuaj yeem tau txais cov teeb liab tawm tswv yim los ntawm ntau qhov chaw suab, xws li microphones, suab paj nruag, suab paj nruag, thiab lwm yam, thiab xa cov teeb liab mus rau ntau qhov kev tso tawm. Piv txwv li, cov twj paj nruag sib txawv tuaj yeem raug xa mus rau cov neeg hais lus sib txawv lossis lub suab lem los sib xyaw thiab ua si ntau lub suab.
Cov tswv yim thiab cov zis tawm tuaj yeem hloov kho kom haum raws li qhov xav tau ntawm cov tshuab suab sib txawv. Piv txwv li, ntau lub suab microphone tuaj yeem sib xyaw thiab tso tawm rau lub suab hais lus, lossis lub suab tuaj yeem muab faib rau ntau thaj chaw sib txawv rau kev ua si.
Teeb liab faib thiab Matrix Switching:
Lub teeb liab tawm tswv yim tuaj yeem muab faib rau ntau qhov kev tso tawm kom ua tiav cov kev sib qhia thiab kev faib tawm ntawm lub suab. Piv txwv li, hauv chav sib tham, ib lub teeb liab microphone tuaj yeem xa mus rau ntau tus neeg hais lus thiab kaw cov khoom siv tib lub sijhawm.
Matrix switching tso cai rau koj hloov pauv sai ntawm ntau lub tswv yim thiab cov zis tawm, ua kom yooj yim hloov ntawm cov suab sib txawv thiab cov khoom siv rov qab. Qhov no muaj txiaj ntsig zoo rau kev ua yeeb yam, rooj sib tham, thiab ntau dua, raws li koj tuaj yeem hloov pauv qhov twg lub suab teeb liab los ntawm thiab qhov twg nws yuav mus.
