Iindaba-Ungayikhetha njani imakrofoni yeDesktop

Ngokunyuka ngokukhawuleza kokurekhodwa kweVidiyo kunye nokudubulwa, ukufundwa kwevidiyo kwi-intanethi, i-karaoke ephilayo, njl.njl kwiminyaka yakutshanje, imfuno yezixhobo ze-hardware nayo ibe yingqwalasela yabaninzi abavelisi be-microphone.

Abahlobo abaninzi baye basibuza indlela yokukhetha ukurekhoda iimakrofoni zedesktop.Njengomvelisi we-microphone okhokelayo kolu shishino, singathanda ukunika iingcebiso kulo mba.

Iimakrofoni zeDesktop ikakhulu zineendlela ezimbini zokujongana: XLR kunye ne-USB.Namhlanje, sazisa ikakhulu ii-microphone ze-USB zedesktop.

Ke, yintoni umahluko phakathi kwee-microphone ze-XLR kunye nee-microphone ze-USB?
Iimayikhrofoni ze-USB zidla ngokusetyenziswa ekubhalweni ngekhompyuter, ukurekhodwa kwelizwi lomdlalo, ukufunda kwiklasi ye-intanethi, ikaraoke ephilayo kunye nezinye iimeko.Umsebenzi ulula kwaye ulungele, iplagi kunye nokudlala, kwaye ifanelekile kwi-novices.

Iimakrofoni ze-XLR zihlala zisetyenziswa kwi-dubbing yobuchwephesha kunye nokurekhoda kwekaraoke kwi-intanethi.Umsebenzi woqhagamshelo unzima kakhulu kwaye ufuna isiseko esithile somsindo kunye nokuqhelana nesoftware yokurekhoda.Olu hlobo lwemakrofoni luneemfuno eziphezulu zokurekhoda indawo ye-acoustic kwaye ifanelekile kwiindawo ezikude.

Xa uthengela i-microphone ye-desktop ye-USB, kufuneka uqonde ngokucacileyo iiparitha kunye neempawu ze-microphone nganye.

Ngokubanzi, iiparamitha eziphambili zeemakrofoni ze-USB zixhomekeke ikakhulu kwezi zalathisi ziphambili:

Uvakalelo

Uvakalelo lubhekiselele kubuchule bemakrofoni ukuguqula uxinzelelo lwesandi lube kwinqanaba.Ngokubanzi, okukhona uvakalelo lwe-microphone luphezulu, kokukhona ukuqina kwenqanaba lokukhupha.Iimakrofoni ezinovakalelo oluphezulu ziluncedo kakhulu ekuthatheni izandi ezincinci.

Umlinganiselo wesampulu/umlinganiselo omncinci

Ngokubanzi, okukhona iphezulu ireyithi yesampulu kunye nesantya esincinci semakrofoni ye-USB, kokukhona ucaca ngakumbi umgangatho wesandi esirekhodiweyo kunye nokunyuka kokuthembeka kwelizwi.
Okwangoku, ireyithi yesampulu yomsindo engama-22 iye yapheliswa kancinci kancinci lishishini lokurekhoda.Kule mihla, izitudiyo ezirekhodiweyo zedijithali zinika kuqala ukusetyenziswa kwemigangatho yomsindo we-HD, oko kukuthi, 24bit/48KHz, 24bit/96KHz, kunye ne-24bit/192KHz.

Ijiko lokuphendula rhoqo

Ngokwethiyori, kwigumbi lobuchwephesha le-acoustic elingangenwa sandi, umda wokuphindaphinda okuviwa yindlebe yomntu uphakathi kwe-20Hz kunye ne-20KHz, uninzi lwabavelisi bee-microphone baphawula i-fr.ijiko lokuphendula elilinganayo phakathi kolu luhlu.

Ubungakanani bomqondiso kwingxolo

Umlinganiselo wesignali ukuya kwingxolo ubhekiselele kumlinganiselo wamandla ophawu lwemveliso yemakrofoni kumandla wengxolo, edla ngokubonakaliswa ngeedecibels (dB).

Ngokuqhelekileyo, ukuphakama komlinganiselo wesignali-kwingxolo ye-microphone, umncinci umgangatho wengxolo kunye ne-clutter exutywe kwisignali yezwi lomntu, kunye nomgangatho ocacileyo wesandi sokudlala.Ukuba i-signal-to-noise ratio iphantsi kakhulu, iya kubangela ukuphazamiseka okukhulu komgangatho wengxolo xa isignali yemakrofoni ingena, kwaye lonke uluhlu lwesandi luya kuziva ludaka kwaye lungacacanga.

Ukusebenza kweparamitha ye-signal-to-noise ye-microphone ye-USB ijikeleze i-60-70dB.Umlinganiselo we-signal-to-ingxolo we-middle-to-high-end-series ii-microphone ze-USB ezinobumbeko bokusebenza kakuhle zinokufikelela ngaphezu kwe-80dB.

Ubuninzi bezinga loxinzelelo lwesandi

Inqanaba loxinzelelo lwesandi libhekisa kobona xinzelelo luphezulu lwesandi oluzinzileyo olunokuthi imakrofoni imelane.Uxinzelelo lwesandi ludla ngokusetyenziswa njengobungakanani bomzimba ukuchaza ubungakanani bamaza omsindo, kunye ne-SPL njengeyunithi.

Ukunyamezela isandi soxinzelelo lwe-microphone yinto ebalulekileyo yokuqwalasela xa urekhoda.Ngenxa yokuba uxinzelelo lwesandi luhamba kunye nokuphazamiseka okupheleleyo kwe-harmonic (THD).Ngokuqhelekileyo, ukunyanzeliswa koxinzelelo lwesandi kwi-microphone kunokubangela ukuphazamiseka kwesandi, kwaye okukhona inqanaba loxinzelelo lwesandi, lincinci ukugqwetheka kwelizwi.

Njengomvelisi we-microphone okhokelayo we-high-tech, sobabini sinokubonelela nge-ODM kunye ne-OEM kwiimpawu ezininzi.Apha ngezantsi kukho i-U yethu ethengisa kakhuluIimakrofoni zedesktop zeSB.
