Izilungiselelo ze-Incoding MP3
Isingeniso
I-MP3 format yindlela ethandwa kakhulu yomsindo wokulalelwayo osetshenzisiwe namuhla futhi iye yahlala iminyaka engaphezu kwengu-10. Impumelelo yayo ingabhekana ikakhulukazi nokuhambisana kwayo yonke indawo. Ngisho nale mpumelelo, kusekhona imithetho oyidingayo ngaphambi kokudala amafayela e-MP3. Lezi zici ezilandelayo zizokunika umbono wokuthi ungalungisa kanjani izilungiselelo zakho zokufaka ikhodi yemiphumela emihle.
Ikhwalithi yomthombo womsindo
Ukuze ukhethe ama-value amakhodi wokufaka ikhodi kufanele uqale ucabangele uhlobo lomthombo wezwi. Isibonelo, uma ufaka ikhodi yezwi eliphansi eliqoshiwe kusuka kumateyimu we-analog futhi usebenzise izilungiselelo eziphakeme kakhulu zokufaka ikhodi bese lokhu kuzochitha indawo enkulu yokugcina. Uma ubuzoguqula ifayela le-MP3 eline-bitrate lama- kbps angu-96 libe linye nge-bitrate engu-192kbps futhi akukho ukuthuthukiswa kwekhwalithi kuzokwenzeka. Isizathu salokhu ukuthi i-original yayingama-32kbps kuphela futhi ngakho konke okuphakeme kunalokhu kuzokwandisa usayizi wefayela futhi ngeke kuthuthukise ukulungiswa komsindo.
Nazi ezinye izilungiselelo ze-bitrate ezijwayelekile ongase uzame ukuzihlola:
- 32 kbps - Ukuqoshwa kwetheyiphu yezwi / ye-analog.
- 128 kuya ku-192 kbps - Ukukhipha amathrekhi kusuka ku-CD.
- I-192 kuya ku-320 kbps - Ukurekhoda imithombo yomsindo eyinkimbinkimbi (leyo equkethe ama-frequencies amaningi, njengomculo we-classical isibonelo).
Ukulahlekelwa kokulahlekelwa
I-MP3 format ifomethi elahlekile futhi iguqula enye indlela yokulahlekelwa (kufaka enye i-MP3) ayikhuthazwa. Ngisho noma uzama ukuguqula ku-bitrate ephakeme, usazolahlekelwa izinga. Ngokuvamile kungcono ukushiya okokuqala njengoba kunjalo, ngaphandle uma ufuna ukunciphisa isikhala sokugcina futhi ungacabangi ukunciphisa ukulungiswa komsindo.
I-CBR ne-VBR
Bitrate njalo (i- CBR ) kanye ne-bitrate eguquguqukayo ( VBR ) yizinketho ezimbili ongakhetha ngazo uma ufaka ikhodi ye-MP3 enezikhwepha kanye nobuthakathaka. Ngaphambi kokwenza isinqumo ngokuthi ungasebenzisa i-CBR noma i-VBR kuzodingeka ucabange kuqala ukuthi uzokulalela kanjani umsindo. I-CBR yisilungiselelo esizenzakalelayo esivumelana yonke indawo nawo wonke amadivayisi we-MP3 namadivayisi we-hardware kodwa akhiqiza ifayela le-MP3 elithuthukisiwe kakhulu. Ngaphandle kwalokho, i-VBR ikhiqiza ifayela le-MP3 elilungiselelwe usayizi wefayela kanye nekhwalithi. I-VBR isaba yisisombululo esihle kunazo zonke kodwa ayihambisani ngaso sonke isikhathi ne-hardware endala nakwamanye amakhodi we-MP3.
