Yuav ua li cas Clipping tshwm sim?
Thaum clipping tshwm sim, es tsis txhob siv lub sine nthwv dej uas ua tau raws li lub suab ib txwm muaj, ib qho squared-tawm thiab "clipped" waveform yog tsim los ntawm lub amplifier, ua rau lub suab distortion.
Ib yam li ntawd, hauv cov suab digital, muaj qhov txwv txog qhov twg lub suab nkag tuaj yeem sawv cev. Yog hais tias lub amplitude ntawm lub teeb liab mus dhau lub digital system txwv, qhov seem ntawm nws yuav muab pov tseg. Qhov no yog qhov tsis zoo tshwj xeeb hauv cov suab digital, vim tias muaj ntau lub ntsiab lus tuaj yeem ploj los ntawm kev kaw suab.

Kev tshem tawm suab clipping
Kev tiv thaiv ib txwm zoo dua li kev kho, raws li cov lus hais mus, thiab siv tau rau kev txiav, ib yam nkaus. Nws raug nquahu kom sau cov suab digital thaum khaws cov teeb liab tawm tswv yim nyob rau hauv qhov txwv. Txawm li cas los xij, yog tias koj muaj cov ntaub ntawv suab digital uas koj xav tau los txhim kho, siv qee cov cuab yeej suab los sim tshem tawm cov clipping kom ntau li ntau tau.
Piv txwv ntawm lub software uas tuaj yeem ua qhov no suav nrog:
- Software media player nrog normalization: Qee tus jukebox software players xws li iTunes thiab Windows Media Player muaj cov yam ntxwv ua haujlwm zoo los ua cov ntaub ntawv audio uas tuaj yeem tiv thaiv cov nkauj los ntawm kev txiav.
- Standalone normalization cov cuab yeej: Cov cuab yeej thib peb lub suab zoo li MP3Gain tuaj yeem ua rau cov lem hauv koj lub tsev qiv ntawv suab paj nruag. Cov cuab yeej no kho cov suab nrov nrov kom ua si ntawm tib lub ntim thiab txo cov suab clipping.
- Audio editors: Cov kev pab cuam no muab ntau txoj hauv kev los ua cov ntaub ntawv audio. Cov kws kho suab xws li Audacity muaj cov txheej txheem siab tshaj plaws kom tshem tawm cov clipping mus tas li.
- ReplayGain: Zoo ib yam li cov cuab yeej software zoo li MP3Gain, cov yam ntxwv no tau ua rau qee tus neeg siv MP3. ReplayGain metadata tuaj yeem pab tau los tiv thaiv cov nkauj nrov los ntawm kev txiav los ntawm cov khoom siv sab hauv digital-rau-analog amplifier.
- CD/DVD-burning software: Disc-burning programs feem ntau tuaj nrog ib qho kev xaiv rau normalize lem, tshwj xeeb tshaj yog thaum tsim cov CDs rau kev ua si ntawm cov khoom lom zem hauv tsev.
