WAV ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-WAV ukuya kwi-MP3 iguquli sesandi?

WAV yisandi engalahlekiyo; MP3 ilahlekile. Umguquli uphinde ubhale ikhowudi ye-waveform kwi-bitrate emiselweyo. Isiphumo sincinci kakhulu kodwa sisusa ezinye iziqulatho zesantya esingalunganga - ngokuqhelekileyo zicacile kwi-192 kbps+.

Yintoni i-bitrate endingakhetha kuyo i-MP3?

320 kbps yomgangatho wovimba, 256 kbps yokufunda ngokucacileyo kwisandi esikhulu, 192 kbps yokusasaza, 128 kbps xa ubungakanani befayile bulawula. Ngaphantsi kwe 96 kbps iindidi zezinto zibonakala kwizinto eziqulethe i-percussive.

Ungaguqula i-MP3 kwakhona kwi-WAV kule ndawo. Ukuba nayiphi na ifomati ebandakanyiweyo ilahlekile, i-round-trip ayizukuba yi-bit-perfect nakuba ibonakalayo okanye icacile.

Ingaba iMP3 iya kuba ncinci kangakanani na kune-WAV yam?

Ngokuqhelekileyo 5-10x ngaphantsi kwemifanekiso, 5-15x ngaphantsi kwesandi. Uthelekiso oluchanekileyo luxhomekeke kumphakamo womgangatho okhethiweyo kunye nento equlethe - imifanekiso ethe tyaba-emnyama nesandi esitshixiweyo sicinezela kakhulu kunemifanekiso ethe nkcukacha okanye iingoma zesandi ezixakekileyo.

I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ndingayiphawula i MP3 ngeenkcukacha zomculi ne-albhamu?

Ewe, kwaye yinzuzo elungileyo ngaphezulu kwe WAV, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. MP3 ithatha igama, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

Yintoni na i-MP3 ifayili?

Uqhubo olumnyama lwee-frames zesandi ezikhowudiweyo ngaphandle komgcini ojikelezayo. Le yisizathu sokuba iifayile ezimbini MP3 zingadityaniswa ngokulula ngokubeka enye emva kwenye, kwaye ngokufanayo kutheni konke okungaphezulu kwesandi - ubude, ukukhangela isalathisi, ubugcisa bokuqubha - kufuneka kuboshwe njenge konvensi kunokuba ibe yinxalenye yefomati, ngoko umdlali kufuneka ufunde ifayile yonke usebenze ukuba ide kangakanani. Kumalunga nento elula ebizwa ngokuba yifayile yesandi, eyiyo isizathu sokuba ivela ngaphakathi kwezinye iziqulathi-zifayili rhoqo kuneyo.

Ijika ezantsi kwi-stereo, kuba MP3 ayinayo indlela esebenzayo ye-multichannel. Ukhuphelo lwe-downmix lusebenzisa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-mandla zixutywe kwinqanaba eliphantsi. Nantoni na exhomekeke kubekwa kwesiqhagamshelanisi esikhethekileyo siphelile xa oko kwenzeka.

MP3

Iifayile zeMP3 zisebenzisa ucinezelo olulahlekileyo ukunciphisa ubungakanani befayile ngelixa zigcina umgangatho wesandi owamkelekileyo kubaphulaphuli abaninzi.
