Isivinini esisodwa sokulinganisa futhi kokubili kubonisa izinga
Uma uzwa imigomo yomsindo wedijithali ngokujula nokuhamba kancane , ungase ucabange ukuthi lezi zinkulumo ezimbili ezizwakalayo zisho ncamashi into efanayo. Kulula ukudidanisa nabo ngoba bobabili baqala ngo "bit," kodwa empeleni bangumqondo ohlukile ngokuphelele.
Kungase kudingeke ukwazi okwengeziwe mayelana nesilinganiso semali uma ukhetha ifomethi yokulalelwayo engcono kakhulu yedivayisi yakho ephathekayo noma uma uguqula kwi-MP3 format nge ithuluzi lokuguqula umsindo noma olunye uhlelo olufana ne- iTunes .
Ukulinganiswa kweBbit ekuqopheni koMsindo
Isilinganiso samancane yisilinganiso esichazwe kilobits ngomzuzwana (Kbps), okuyizinkulungwane zezinkinobho ngomzuzwana. I-Kbps iyinani le- bandwidth yemishini yokudlulisela idatha. Kubonisa inani lemininingwane egeleza ngesikhathi esinikezwe kunethiwekhi.
Isibonelo, ukurekhoda okunama-320 kbps bit rate kusetshenzwa ku-320,000 bits ngomzuzwana.
Qaphela: ama- bits ngomzuzwana angabonakala nakwezinye izinyunithi zokulinganisa njenge-megabits ngomzuzwana (Mbps) kanye ne-gigabits ngesigamu (Gbps), kodwa lezo zisetshenziswa kuphela lapho amabhuzu ngesigamu ehlangana noma edlula 1000 Kbps noma 1000 Mbps.
Ngokuvamile, ukurekhoda okuncane kakhulu okurekhodiwe kunika umsindo wekhwalithi engcono futhi kuthatha isikhala esiningi kukhompyutha yakho noma kudivayisi yeselula. Kodwa-ke, ngaphandle kokuthi ube nezinduna zekhwalithi eziphezulu noma izikhulumi, ngeke ukwazi ukubona ikhwalithi ethuthukile ngaphezu kweyodwa yekhwalithi ephansi.
Ngokwesibonelo, uma ulalele i-earbuds ejwayelekile, cishe ngeke uqaphele umehluko phakathi kwefayela le-128 kbps nefayela le-320 kbps.
Ungafunda kabanzi mayelana nesilinganiso samancane somunye ulwazi olwengeziwe, kufaka phakathi ukuthi luhlobene kanjani nokucindezelwa komsindo.
Ukujula kancane
Ekuqaleni, ukujula kancane kungase kubonakale kuyinkimbinkimbi, kodwa ngendlela elula kakhulu kuyindlela nje yokuthi umsindo uzwakala kanjani kumsindo we-digital. Ukuphakama ukujula kancane, kunembile kakhulu umsindo we-digital.
Cishe usuvele uhlangabezane nezingoma ezifika ngesilinganiso esithile, noma izinsiza zokulanda ze-MP3 noma ukusakaza amasayithi omculo , kodwa ngokungajwayelekile kukhulunywa kakhulu ngokujula kancane.
Ngakho, kungani ukhathazeka ukuqonda ukujula kancane?
Uma uzokwengeza imiqoqo yakho yamarekhodi e-vinyl noma amathebula e-analog ukuze uwagcine njengamafayela omsindo we-digital digital, ngakho-ke udinga ukwazi ngokujula kancane. Ukujula okuphakeme okuphezulu kunika ukuqoshwa komsindo okuningiliziwe. Ukujula kancane kancane kubangela imisindo ethule ukuthi ilahleke.
Isibonelo, i-Compact Disc Digital Audio isebenzisa ama-bits angu-16 ngesampula ngenkathi i-Blu-ray Disc ingasebenzisa amabhuzu angu-24 kwisampuli ngayinye.
Lesi sici sithinta ukuthi uthola imininingwane engakanani kusuka kumarekhodi okuqala analo. Ukuthola ukujula kancane kwesokudla kubuye kubaluleke kakhulu ekugcineni ukuphazamiseka kwesignali sangemuva okungenani.
Ungafunda kabanzi mayelana nokuthi ukujula kancane kuthinta ikhwalithi yomsindo lapha .
