Cov lus qhia dav dav los pab koj nkag siab qhov tob me ntsis hauv suab.
Dab tsi yog qhov tob tob hauv Suab?
Qhov tob me ntsis, tseem hu ua piv txwv qhov tob lossis lo lus ntev, hais txog cov khoom siv los sawv cev rau txhua tus qauv suab hauv cov ntaub ntawv suab digital. Xav tias nws yog qhov kev daws teeb meem ntawm koj lub suab – ib yam li cov duab daws teeb meem txiav txim siab qhov pom kev pom tseeb, qhov tob me ntsis txiav txim siab qhov ntau thiab tsawg ntawm koj lub suab digital. Txhua qhov me me muab kwv yees li 6 decibels ntawm qhov sib txawv, yog li 16-ntsis suab muaj txog 96 dB ntawm ntau yam, thaum 24-ntsis suab muab kwv yees li 144 dB. Qhov tob me ntsis ncaj qha cuam tshuam rau lub teeb liab-rau-suab nrov piv thiab tag nrho kev ncaj ncees ntawm koj cov kaw suab. Ntau qhov tob me ntsis tuaj yeem ntes ntau qhov hloov pauv hloov pauv hauv qhov ntim thiab lub suab nrov, ua rau cov suab nrov dua, cov ncauj lus kom ntxaws ntxiv. Txawm li cas los xij, qhov siab dua me ntsis kuj txhais tau tias cov ntaub ntawv loj dua thiab yuav tsum tau ua kom tiav. Kev nkag siab me ntsis qhov tob yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog cov suab digital, txawm tias koj tab tom kaw, kho, lossis tsuas yog sim ua kom tiav lub suab zoo tshaj plaws rau koj cov haujlwm.
Common Audio Bit Depths piav qhia
Qhov feem ntau ntsib qhov tob me ntsis hauv cov suab yog 16-ntsis, 24-ntsis, thiab 32-ntsis, txhua qhov ua haujlwm sib txawv thiab kev siv. 16-ntsis suab yog tus qauv rau CD zoo thiab feem ntau cov neeg siv suab tawm tswv yim. Nws muab ntau yam muaj zog txaus rau feem ntau cov xwm txheej mloog thiab ua kom cov ntaub ntawv loj tuaj yeem tswj tau. Qhov tob me ntsis no tuaj yeem sawv cev rau 65,536 qhov sib txawv amplitude theem, uas txhais tau hais tias qhov kev hloov pauv ntawm qhov kwv yees li ntawm 96 dB. 24-ntsis suab tau dhau los ua tus qauv kev tshaj lij rau kev kaw thiab sib xyaw. Nrog rau ntau tshaj 16 lab qhov ua tau amplitude theem, nws muaj ntau lub taub hau thiab nthuav dav dua li 16-ntsis suab. Qhov no ntxiv precision yog tshwj xeeb tshaj yog muaj nqis thaum lub sij hawm kaw thiab kho cov txheej txheem, qhov twg ntau txheej txheej ntawm kev ua yuav ua rau muaj kev sib hloov tsis raug. 32-ntsis suab, feem ntau nyob rau hauv floating-point hom, muab zoo unlimited headroom thiab feem ntau yog siv nyob rau hauv cov kev digital audio workstations rau sab hauv, tab sis nws yog tsis tshua muaj tsim nyog rau qhov kawg tso zis tawm tswv yim.
- 16-ntsis: CD zoo, 96 dB dynamic ntau yam, cov ntaub ntawv me me
- 24-ntsis: Tus qauv kev tshaj lij, 144 dB dynamic ntau yam, zoo dua rau kev kho

Bit Depth cuam tshuam li cas ntawm Suab Zoo
Qhov cuam tshuam ntawm qhov tob me ntsis ntawm lub suab zoo dhau los ua qhov pom tseeb tshaj plaws hauv cov lus nyob ntsiag to thiab thaum lub sijhawm hloov pauv hloov pauv. Qhov qis me ntsis qhov tob tuaj yeem qhia txog lub suab nrov nrov, uas dhau los ua suab nrov raws li kev hnov ​​​​mob lossis grittiness, tshwj xeeb tshaj yog nyob rau hauv cov lus kaw tseg. Lub suab nrov hauv pem teb no ncaj qha ntsig txog qhov tob me ntsis – txhua qhov ntxiv me ntsis zoo ib nrab ntawm cov suab nrov. Hauv kev xyaum, qhov no txhais tau hais tias 24-ntsis cov ntaub ntawv kaw tau tuaj yeem ntes cov suab nrov ntau yam tsis tas yuav npog lub suab nrov digital. Qhov tob me ntsis kuj cuam tshuam qhov tseeb ntawm kev ua suab digital. Thaum koj siv cov teebmeem, kho cov theem, lossis ua ib qho kev tswj xyuas digital, cov kev suav suav nrog tuaj yeem ua rau muaj txiaj ntsig uas poob ntawm qib quantization muaj. Qhov siab me ntsis qhov tob muab qhov tseeb ntau dua rau cov txiaj ntsig nruab nrab no, txo qis kev ua yuam kev uas tuaj yeem ua rau lub suab tsis zoo los ntawm cov saw hlau ntau lawm. Qhov no yog vim li cas cov kws tshaj lij audio engineers feem ntau sau thiab hloov kho ntawm 24-ntsis, txawm tias qhov kawg xa tawm yuav yog 16-ntsis.
Xaiv qhov zoo me ntsis qhov tob rau koj xav tau
Xaiv qhov tsim nyog me ntsis qhov tob yog nyob ntawm koj cov ntaub ntawv siv tshwj xeeb, kev txwv cia, thiab cov kev xav tau zoo. Rau kev mloog zoo ib yam thiab cov neeg siv khoom siv feem ntau, 16-ntsis suab muab qhov zoo tshaj plaws thaum tuav cov ntaub ntawv tsim nyog. Cov kev pabcuam streaming, rub tawm digital, thiab cov tshuab ua si feem ntau tau ua kom zoo rau 16-ntsis suab, ua rau nws qhov kev xaiv zoo rau kev faib tawm thiab mloog txhua hnub. Rau kev kaw, kho, thiab kev ua haujlwm suab, 24-ntsis feem ntau pom zoo. Lub taub hau ntxiv tso cai rau kev ua kom nruj dua yam tsis muaj kev puas tsuaj zoo, thiab cov suab nrov qis hauv pem teb muab cov ntaub ntawv huv si ntawm qhov chaw ntsiag to. Thaum ua haujlwm nrog ntau txheej ntawm cov suab lossis cov txheej txheem ua haujlwm nyuaj, pib nrog 24-ntsis cov khoom muab rau koj yooj yim dua los tswj kom zoo thoob plaws hauv cov txheej txheem ntau lawm. Xav txog koj lub peev xwm khaws cia, lub zog ua haujlwm, thiab npaj hom ntawv kawg thaum txiav txim siab qhov no.
