Iyo iPhone 6 haisati iine yakakwira-resolution odhiyo

Mushure mekudyara muBeats, ichiwedzera huwandu hwekuchengetedza kusvika ku128 GB uye ichishanda pane yayo mimhanzi yekushambadzira system, izvozvi zvishandiso hazvigone kuburitsa iri yepamusoro mhando kurira. Muchokwadi, Tim Cook haana kutaura nezve Hi-Res odhiyo rutsigiro payakaunza iyo iPhone 6 uye iPhone 6 Plus.

Yakakwira-resolution odhiyo (HD odhiyo) inowanzozivikanwa senzwi rinoenda kupfuura CD mhando, uye hachisi chinhu chataitarisira sehunyanzvi, asi mushandirapamwe waNeil Young paKickstarter watsvairisa chirongwa chake PonoPlayer, inova iri iPod inoridza mimhanzi-yepamusoro resolution.

Muhuwandu

Yakakwira tsananguro odhiyo inorasika isina odhiyo, isina kumanikidza. Pane manhamba maviri anotipa pfungwa yeichi chinzvimbo, ndeaya:

• Kakawanda uye sampling chiyero, frequency chiratidzo cheizvo nzeve yemunhu inogona kunzwa, zvinofungidzirwa kuti tinonzwa kusvika kuma20 kilohertz uye pamusoro pechiyero ichi inoonekwa seisinganzwisisike kuvanhu (inonzi ultrasound). Kazhinji iyo sampling rate yedhijitari odhiyo yekurekodha inofanirwa kuve yakapetwa zvakapetwa pazere kutambiswa, iyo odhiyo CD inoshandisa muyero rate ye 44,1 makirogiramu, iyo inovhara ruzha inosvika angangoita 22 kilohertz frequency.
• Kugadzirisa, ndiyo nhamba yemabheti anoshandiswa kuchengeta yega sampuro yechiratidzo cheanalogog, odhiyo yedhijitari ichave nayo humwe hunhu hunokwidzirisa chisarudzo chayo. Iyo CD inoshanda ine gumi nematanhatu bits.

La resolution yepamusoro inoshanda nesampling frequency ye 192 makirogiramu, inokwanisa kubereka ruzha kusvika 96 kilohertz uye nechisarudzo che 24 matomu.

Chokwadi

Pane gakava rakawanda pamusoro pekuti iko kuvandudzwa kweyekuteerera mhando kuri zvinonzwisisika nemunhuKana kuwedzera chisarudzo ichi hakukonzere kupokana nemidziyo yazvino yekuteerera.

Ini ndinotenda kuti kusimudzira kwemhando yepamusoro kwakafukidzwa ne kukanganisa, iyo ingave nehasha; zvishandiso zvekuteerera zvitsva senge masipika uye mahedhifoni, kudiwa kukuru kwenzvimbo yeiyo kuchengetedza yemimhanzi uye zvakanangana nezvinodiwa zvemafomati izvo zvinogona kuchinja mamiriro eiyo kutamba software zvazvino

Chidzidzo

Kuedza iyo yepamusoro-resolution odhiyo kugona kweiyo iPhone 6, Mashable akashanda nevakawanda toni dzekuyedza, inogadzirwa nehunyanzvi-yekuyedza nyanzvi, David Ranada, uye nesampula rate ye96 kHz uye makumi maviri nemana mabhureki pane imwe fomati muWav fomati, aya akatorwa akananga kubva ku iPhone headphone jack uye yakanyoreswa pakubuda mu Hi-Res Audio sahwira iyo inoshanda nesampula rate ye96 kilohertz uye ine makumi maviri nemana mabhii pane imwe sampuro.

Aya marekodhi akabva aiswa Adobe Audition yekuenzanisa nezviratidzo zvekutanga, iyo isingakwanise kuridzwa neTunes (inopa kukanganisa) saka maapplication eHD odhiyo akashandiswa,  Onkyo's HF mutambi wemimhanzi uye OraStream's app.

Kana iyo toni yekuyedza ichiridzwa kuburikidza neiyo iPhone pane ese OraStream uye Onkyo, huwandu hwekuburitsa hwakaderera zvakanyanya apo iyo frequency yakakwira pamusoro pe18 kilohertz, kudzamara yasvika 22 kilohertz, uko chiratidzo yakabviswa zvakananga.

Kana ari chisarudzo, musiyano uripo pakati peruzha unouya kubva kujack ye iPhone unoshamisa uchienzaniswa neOnkyo.

CONCLUSIONS

IPhone 6 haina kutamba Hi-Res Audio, ingangoita kukamurwa kune zvine chekuita nesoftware pane neiyo Hardware. Iyo dhijitari kune analog converter (DAC) kana chii chakafanana, chidimbu chehardware chinoshandura mabhijitari kuita mumhanzi, ndiyo Cirrus Logic 338S1201 chip, maererano nemisodzi ichangoburwa.

Iyi chip inogadzirwa kuyera Apple, ipapo zvirevo hazvisi munzvimbo yeruzhinji, asi kuve chikamu chayokuenda kuCD42L renji yekambani, zvinowanzoitika kuti kukwanisa kubereka zvemhando yepamusoro odhiyo (24 bits uye 96 kilohertz).

Izvo zvinotisiira isu nenyaya yekuti kukamurwa kweApple kuburitsa odhiyo kusvika kuCD mhando kunoonekwa ne tsvaga yepamusoro bhatiri kuita, iyo inoverengerwa mumaawa anopfuura makumi mashanu eiyo iPhone 50 uye 6 maawa eiyo iPhone 80 Plus.
