Ko Muenzaniso Wekugadzira Unobatsira Unhu hweMimhanzi Here?
kHz inononoka kilohertz, uye inyanzvi yehuwandu (maitiro nekondi). Mumutauro we digital, ichi chiyero chinorondedzera nhamba ye data chunks inoshandiswa pamushure wechipiri kuti inomiririra rwiyo rweanalogog mune fomu yejedi. Izvi zvinyorwa zvinyorwa zvinozivikanwa semuenzaniso wezvidzidzo kana sampuli yenguva dzose.
Iyi tsanangudzo inowanzovhiringidzwa nemamwe mazwi anozivikanwa mumutauro we digital, anonzi bitrate (akayera mu kbps). Zvisinei, musiyano pakati pemitemo miviri ndeyekuti kutengesa kunongedzera kuwandisa kwakadini shanduro yese yechipiri (ukuru hwezvinyorwa) panzvimbo yehuwandu hwezvinyorwa (kazhinji).
Cherechedza: kHz dzimwe nguva inonzi sampling rate, nguva yechitsanangudzo, kana mitsindo pamushure.
Common Sampling Rates Yakashandiswa Digital Digital Content
Muhurukuro yedijitari iyo yakawanda yakawanda yemaitiramu yemitambo yaunosangana nayo inosanganisira:
- 8 kHz yekutaura, mabhuku ehurukuro , nezvimwewo.
- 22 kHz yekodhizedhi yeanalogog mono recordings yakadai sevinyl zvinyorwa uye kaseti matepi
- 32 kHz yekutamba mumimhanzi, zviteshi zveredhiyo
- 44.1 kHz inoshandiswa pamavhadhi akanzwika uye inowanzoenderana nemitambo yakakanganwa mimhanzi (kufanana neTunes) mumafomu akaita MP3 , AAC , WMA , nevamwe
- 48 uye 96 kHz inoshandiswa pakutsanangurwa kwepamusoro-soro uye inyanzvi yekuteerera
Ko kHz Determine Audio Quality?
Mune nharo, yakakwirira yekHz kukosha iyo inoshandiswa, zviri nani hutano hunove huchave huchava. Izvi zvinokonzerwa nemamwe data chunks anoshandiswa kurondedzera waveform waveform.
Izvi zvinowanzoitika mune zvakaitika mumimhanzi yedijiti ine musanganiswa wakaoma wezvivako. Zvisinei, iyi dzidziso inowira pasi paunenge uchitarisana nedzimwe mhando dzeanorog inzwi sekutaura.
Shanduro yakakurumbira yehuwandu hwekutaura i8 kHz; nenzira iri pasi peCD audio quality pa 44.1 kHz. Ichi ndechokuti inzwi revanhu rine mararamiro anowanzoita anenge 0,3 kusvika ku3 kHz. Nemuenzaniso uyu mupfungwa, yakanyanya kHz haisi nguva dzose inoreva kunaka kwepamhanzi audio.
Ndezvipi zvakanyanya kuti iyo inowanzokwira kune maitiro ayo vanhu vakawanda vasingakwanisi kunyange kunzwa (kazhinji anotenderera 20 kHz), zvakataurwa kuti kunyange iyo inaudible frequencies inogona kukanganisa kunaka kwehutano.
Iwe unogona kuedza izvi nekuteerera kune chimwe chinhu pahuwandu hwepamusoro yepamusoro iyo iyo inzwi yako inzwi inotsigira asi kuti iwe haufaniri kunzwa, uye iwe ungawana kuti zvichienderana nemidziyo yako, iwe unonzwa chaizvo kuvhara, mhere, uye mamwe manzwi .
Izwi iri rinoreva kuti chiyero chemuenzaniso chinenge chakanyanya kukwirira. Iwe unogona kutenga zvigadzirwa zvakasiyana-siyana zvinogona kutsigira izvo zvidimbu kana iwe unoderedza chiyero chekuenzanisa kune chimwe chinhu chinogona kutarisirwa, sa 44.1 kHz.
