Ukujongwa kwenkxwaleko yokulahlwa kwemvalo kunye nendlela ekuchaphazela ngayo umculo we-digital
Yintoni eyenza iFomatic Format ilahleke?
Igama elilahlekileyo lisetyenziswe kwisandi sedijithali ukuchaza uhlobo loxinzelelo olusetyenziswa ukugcina idatha echanekileyo. I-algorithm esetyenzisiweyo kwifomathi yomsindo olahlekileyo iyancipha idatha yedatha ngendlela elahla ulwazi oluthile. Oku kuthetha ukuba i-audio encoded ayifani neyoqobo.
Umzekelo, xa udala uchungechunge lweefayili ze- MP3 ngokukrazula enye ye-CD yomculo wakho, ezinye zeenkcukacha ezivela kubhaliso lwangaphambili ziya kulahleka-ke ngoko ukulahleka kwexesha. Olu hlobo loxinzelelo alugcini nje kuphela kumsindo kuphela. Iifayile zefayile kwifom ye-JPEG ngokukodwa zinyanzeliswe ngendlela elahlekileyo.
Ngokuqinisekileyo, le ndlela ihambelana nokunciphisa ukulahla komsindo okwenzelwe iifom ezifana ne- FLAC , i- ALAC nabanye. I-audio kulo mzekelo icinezelwe ngendlela engayishiyi naliphi na idatha. I-audio ke ngoko ifana nomthombo wokuqala.
Ukusebenza Kokunyanzeliswa Kwenzeka njani?
Ukunciphisa ukulahleka kwenza ukuba umntu acinge ngeengxaki ezithandwayo ukuba indlebe yomntu ayifumane. Ixesha lobugcisa lokufunda ingcamango ephilileyo ibizwa ngokuba yi- psychoacoustics .
Xa ingoma yomzekelo iguqulwa kwifomathi yomsindo olahlekileyo njenge-AAC, i-algorithm ihlalutya zonke ii-frequencies. Emva koko iyalahla ukuba indlebe yomntu akufanele ikwazi ukuyijonga. Kwiindawo eziphantsi kakhulu, ezi zifakwe ngokucoca okanye ziguqulwa zibe zibonakaliso ze-mono ezithatha indawo encinane.
Enye inqubo esetyenziswe kwakhona ukulahla izandi ezithulekileyo ezingenakwenzeka ukuba umphulaphuli angazibona, ingakumbi kwinxalenye enkulu yengoma. Oku kuya kunceda ukunciphisa ubungakanani befayili yomsindo ngelixa kunciphisa impembelelo kumgangatho olalelwayo.
Ukunciphisa iLossy kuthinta njani umgangatho wezandi?
Ingxaki ngokunyanzeliswa kwelahleko kukuba iyakwazi ukuvelisa izinto ezikhoyo. Ezi zizandi ezingathandekiyo ezingekho kwi-rekodi yokuqala, kodwa ziyimveliso ye-compression. Ngelishwa ilanga lihlaziya umgangatho we-audio kwaye ingabonakala ngokugqithiseleyo xa kusetyenziswa i-bitrate ephantsi.
Kukho iintlobo ezahlukeneyo zeempahla ezinokuchaphazela umgangatho wokurekhoda. Ukuphazamiseka kungenye yezona ziqhelekileyo oza kufikelela kuzo. Oku kunokwenza iidrama umzekelo obuthathaka ngaphandle kwesigxina. Izwi kwingoma linokuchaphazeleka. Izwi lomculi linokukhalaza inkcazo kunye nokungabi nalwazi.
Kutheni uCompress Audio kwiWonke?
Njengoko usuyazi, iifomati ezininzi zedijithali zisebenzise uhlobo oluthile lokuncintisana ukuze kugcinwe isandi ngendlela efanelekileyo. Kodwa ngaphandle kwayo, ifayile ifayile ibe enkulu.
Umzekelo, ingoma yomzuzu engama-3 igcinwe njengefayile ye-MP3 ingaba malunga no-4 ukuya ku-5 Mb ngobukhulu. Ukusebenzisa ifomathi ye-WAV ukugcina le ngoma enye ngendlela engagxininiseki iya kubangela ubungakanani befayile malunga ne-30 Mb - ubuncinane amaxesha amathandathu. Njengoko ubona kule ndawo (ngokugqithisileyo) ukuqikelela, iingoma ezingaphantsi kakhulu ziya kufana nomdlali wakho weendaba ophathekayo okanye i-hard drive yekhompyutheni xa umculo ungacinezelwa.
