DAC tangi: tikanga whakamātau

ite kore kaiwhakamahi rorohiko katoa e i roto i te meka ko te DAC. rongo i te tangi te mea katoa, engari e te te ara e whawha atu ai, kia rite huri i te reira i roto i, ko te wae iho. I roto i te whakaaro o te kaupapa ka whai i te iti hohonu ki te āhua o te māramatanga tangi me te tārua i ngā pūrere reira.

He aha te mea te DAC? Tangi: he māramatanga taketake

Ētahi iwi hape whakapono e te DAC - ko te pūtukatuka ororongo pokapū. Tetahi wahi no te mea he reira. Otiia i roto i te meka, te DAC ko te kaitahuri auau-ki-tairitenga, e ketia te tohu oro, me ki te ahua taua, ka mohio nei e te taringa tangata.

Here e hiahia ana koe ki te hanga i te rerekētanga i waenganui i mamati me tairitenga tohu. Te hangarau e whakamahia ana i roto i te "ahua" ranei ka whakamamati oro, ngā tikanga tukatuka pūmanawa, i te mea he aha ki te maha pā o ngā pūkete vinyl whakarongo ki te record rite i runga i CD / DVD-puku e kore e anake e tika ana ki te kore o te huri motuhake tukuna e te matenga taimana o te kaitākaro ka pa ki a koutou te paraharaha .

Analog tukatuka i whakamahia tuatahi i roto i amplifiers ngongo, me te hurori rīpene kaiwhakamahara. He tino hira i roto i kaiwaiata ngaio nei e ngana ana ki te tāpiri ki te reo o tona tito etahi wera tonu taua whakaaro.

āhuatanga auau

Ko te faafariu tangi DAC me reproducible, tei runga i te pūrere huaputa tohu, i.e., kāri tangi. Otiia e kore e katoa te e. He wāhi nui takaro e te kaikōrero rite te taua kaikōrero (kaikōrero) me amplifiers.

Here e ti'a ia tatou ia maramarama e, e tā kore pūnaha te tangi o te tawhā raro wāhitanga saundkarty. Ka rite ki o tenei ra, ki te kore koe e haere ki nga kōrero o te mahi o taua whakaaro, te pai ko te āhuatanga e whai ake nei:

• te auau tauira i 48 kHz (i paerewa 44.1 kHz);
• hohonu o 24 32 ranei paraire (ahakoa te paerewa 16 paraire);
• auau moka 320 kbit / s me teitei (ahakoa te paerewa 128 kb / s).

Ētahi atu kōwhiringa Rapu

Ka rite ki te auautanga tawhā me tango ki whakaaro te meka e te haruru o te DAC kēne taata faafariu te whakamahi i te tangi tawhā, i mohiotia e te tangata taringa. Ko reira utu ki te noho i runga i te mea e taea e tatou e rongo.

Whāititanga o to tatou ngā rongo i 16 Hz ki te 20 kHz (me ētahi wā 22 noa ranei 24, engari he onge tenei). Na tukinotia katoa tangi DAC nui i roto i tēnei awhe. mutu i muri i runga i te tikanga whakamātautau, whakaarohia e tetahi o te tino rongonui rauemi ipurangi.

Marohi tukanga whakamātau DAC

Hoki whakamatautau tikanga tangohia whakaaro waho, kihai integrated saundkart no te mea kei te whakapono ratou ki te whai i nga āhuatanga o te tikanga o te nui o raro whakaritea ki te taputapu waho.

I roto i te e tono ngā i roto i te tangi-kounga tiketike ki te DAC whakamatauria te i runga i te pūtake o AudioDoctor FSQ 2006 hangarau, e, Heoi, i hangaia tuatahi ki te whakamatautau i te pūnaha ororongo motokā, a anake i muri taunga ki te taiao kāinga. Pūrere, tuku ki rite DAC, hono te tika mā te USB-atanga me e S / PDIF te whakamahi i RCA ngä haurangi (ngä taurite XLR kia whakaatu āhuatanga tino rerekē).

whakaritea tūranga Own ko Converter M2Tech HiFace Evo, i nei faafariu kōnae i roto i te hōputu tino pānui. whakamana te whakamātautau whakahauanga i te whakamahi i asio taraiwa.

Whakatauranga DAC kongakonga i runga i te tangi

Ko whakakitea te hua? DACs Reiti i runga i te tangi rite ki te whai ake:

• ASUS Essence III;
• Burson Audio Pūtātaki Virtuoso 9018;
• Cary Ororongo DAC100;
• Rauoro 2Qute;
• Densen DenDAC 50;
• Fostex HP-A8;
• Te Tai Tokerau Star Hoahoa Supremo;
• Huihia HA-1.

Ko te tino herenga te raupapa, no te mea he reira maha noa atu motuhake o te āhuatanga tangi, me te utu.

Heoi, whakaatu ana Cary Audio i runga i tenei rārangi i te mahi teitei me te tangi, me te tīwharawhara aano. Ano, e kore e wareware i te whakatauranga o DAC tangi ngā etahi āhuatanga mōhiotia o ngā pūrere o tenei momo.

Mā te kāri tangi

E hangaia foaki mo te whakamahi i roto i kāri tangi. Kia pehea te Ko te DAC? Sound (whakapumautia parau tumu o te mahi te) tāruatia te hāngai i runga i te faafariuraa o te tohu mamati i te wāhi ki te waehere-rua, i ia uara i hāngai ki te tetahi ngaohiko, o nāianei, me te tiaki.

whakahaere pūrere ADC i runga i te parau tumu whakamuri. Otiia ki te tirohia e koutou tika ki te DAC, te tangi, tāruatia te whakaahuatanga o te huringa ka e kia kōrero i raro kei te anake i runga i te pūtake o te waehere tāuru. whakamahi hoki tona pūnaha perception te hangarau PCM paerewa. He tokomaha, pea, whakarongo e kua tohua te paerewa WAV-kōnae āta rite PCM.

Otiia torutoru anake i wātea te DAC. E kore te mea taea te tukatuka tangi tohu me te whakaputa uri i waho te whakamahi o taputapu pūmanawa e tika ana i huaina kotēkē. Ratou tika whakaturia ake ki te saundkarta taea ia ite raraunga taumai a tā te tangi i te kaikōrero. Kotēkē me pūtahuri i roto i tenei mahi take rite te piriti i waenganui i te tetahi waehere tau, me te "te rino" pūrere (rite ki te āhua o te DirectX).

Sound kāri, kei hea te pūtake kei te whakamahi o te DAC, koe Ko te nuinga e pā ana ki waho whakaaro, e kore tango, tāutatia i te mokamoka ki runga ki te kaupapa, e kore ki whakahua te integrated haruru maramara rite Intel Audio me Realtek.

DAC (auraa kōwae tangi waho te) ahei o te tukatuka ona ake tikanga (te hanga hoki tenei reira). Otiia ki te tuku i te tohu tukatuka ki te pūrere purei e hiahia ana koe ki a mahi reira tika. Na konei i waho hōtaka mana arawhiti, ka karanga taraiwa, he mahuinga ia.

pūrere atekōkiri

Te nuinga o kāri tangi whakahaere pūnaha o tetahi momo takoto te aunoa. E tāuta Atekōkiri i ona ake pātengi. Heoi, kia rapu tahi mau whakaaro tāutanga ā-, e kore taraiwa anake, engari ano hoki nga kotēkē e hāngai ana (hei tauira, he mōkihi K-Lite kōtēke Pack).

E kore e ki te whai wāhi i roto i tenei ahua o ngā tukanga mō te DAC katoa hua tangi pai tāutanga atekōkiri whakahou ranei (pupuri ratou ki runga ki te rā), arā ki te āwhina o ngā whakahōunga pūmanawa aunoa motuhake. Ko tētahi o te hunga ko te Driver Booster whaipainga i uru tuatahi i runga i te kaiwhakanao pūmārō rauemi Ipurangi, a ka tikiake te atekōkiri pūrere tino tata aunoa kitea me whakauru ki roto ki te pūnaha.

pūmanawa

e kore e taea tangi tukatuka i roto i te DAC waho te pūmanawa e tika ana. Mō kotēkē me ngā atekōkiri kua mea. Otiia i konei te te whakanoho te kounga tino pai tangi, ranei ara tukatuka oro, rite maha Engineers tangi, e kore i taea e hua i waho te whakamahi o te pūmanawa.

E kore e ki te whakahua i te tāutanga o taraiwa, he reira e minaminatia ki te whai i tētahi hōtaka rorohiko rite SoundMax. Taua taputapu, i roto i te rerekē ki te pūnaha whakahaere taua taputapu tukua ki a koe tango-rangi.

Hoki tukatuka ororongo he pai ki te whakamahi i ētita motuhake, i roto i nei, i te ara, ka taea e ara e koe te huri i te tautuhinga taunoa, tae atu tauira auau me te hohonu. Ki te tāuta ASIO4ALL taraiwa i roto i whakarara i roto i te rōpū kita tino tangi ki te huri i ngā āhuatanga pērā i te maha o ngā tauira (hei tauira, 512, e hāngai ana ki te auau roa o 10 ms), e kore e ki te whakahua i te kounga tangi (hei tauira, e kore te mea whakaturia uara 44100 Hz, me , mea, 48 96 ranei kHz).

Hangarau Mobile

oro Best i tou atamai ki te DAC taea e tino noho ki te whakatau tata. whakaaro tika, mo te taua, mo te tārua iarere iti te hiahiatia e ōrite ana kaikōrero ki te diameter o 32 inihi. A i reira i roto i to koutou waea papa ranei, ka tangohia e te reira?

Heoi, e taea te hoatu hiahia ki hua nei tūnga tuatahi rite te matamua-whanau i roto i te mara o te tukatuka tohu me nga kaiwhakatū o tenei momo o te hangarau. Sony Corporation - he haamauraa a Tūrongo.

A, no te tīpako koe i te pūrere ki te kia meinga tauira ki whare kirihou, no te mea he nui teitei te whakaata o te tangi i roto ia ratou e to ratou āhuatanga me te taumata. tinana Metal ara, ki te te tāutanga o te pūtahuri kaha tino titiro nui ngoikore. Ko te tika tenei anake ki te meka e absorbs tangi te whakarewa. Ano, ko te nui te wāhi i waenganui i te whākaha reo tini haere matua me te uhi hoki, i te pai te whakaata. Otiia e kore e overdo koe i te reira, pera nui rawa e taea te te waere meinga pānga taha, Reverb ranei himene, atu ranei noa, hē te tangi i roto i tona putanga taketake.

Āhuatanga atu

he mārama rite, e hāngai ana te tukatuka tangi DAC i runga i te waehere ā-rua mamati, te whakamahi i te huringa i roto i te ngaohiko me te auau. Otiia i konei me mahino ano tatou e kore e anake taua āhuatanga o tenei momo o te pūrere iti. I roto i nga tawhā katoa e kua whakamahia i roto i te whakaahuatanga o ia DAC taea te kitea maha ngā uara ke rite auautanga-poipoi tawhā PCM puoro. Ko rite tenei te parau tumu taketake o tino nga pūtahuri katoa.

I roto i te take māmā, e hāngai ana te tātari tāuru tohu me tona faafariuraa te i runga i te parau tumu o Whakarāpopoto nga uara o ngaohiko, o nāianei, me te tiaki i te hunga i roto i ngā mamati taea te tango rānei i te uara kore ranei tetahi (e hāngai ana i runga i nga tikanga o te tono o te waehere ā-rua).

Wehe, he mea utu aufauraa i te whakarongo ki nga tawhā pērā i moka, ētahi wā hoki i huaina taumira, te taahiraa quantization, te āhuatanga whakawhiti o te auautanga Nyquist (tīpako), te whānuitanga o te tawhā tāuru tohu, monotonicity, te putanga tukunga mā te huri i te raraunga i roto i te tetahi wā o te wā, te hapa wāhikē i waenganui i te tūturu ranei tohu me ngā tawhā riro hei "pai", wāhi me te pārōnaki āhuatanga linearity-kore o te rerekētanga i roto i te rerekētanga kitea i roto i ngā āpiti e tohu dnyh.

kia hāngai ki te transistor ki i tonoa he tohu te ki DACs ia uara o te waehere ā-rua. E wehea pūtahuri waea ki whakarara me te rangatū. Tonu, kei te tahuri ratou ki ngā pae mains, te pāhekoheko me te putanga.

hāngai te nuinga o nga whakaaro hanga i runga i te R kopu - 2R, i te mea tetahi o te noa tino me tēnei wā i roto i te whakamahi hanganga whakamahi rua anake ngā uara o te ātete, i waenganui i te i roto i te ōwehenga o te 2: 1. Ko te kupu, heke te DAC te ki tikanga whakamātautau e rua: faaotiraa o te ngaohiko me te nāianei i roto i te noa, me te whakataka ataata. tutuki ai tenei te tamau o te tawhā parenga ia me te te kore o ngā capacitive. Ko te ngoikoretanga, ko e te puna matua mo te huru tohutoro ko te aroaro o te parenga ia rawa iti. I tua atu, e kore e taea ki te unga i te tohu ki te whakamahi i te parenga iahiko hono i roto i te raupapa ki te pūtake tohutoro. Otiia i roto i tenei kaupapa, te hononga kei te nuinga o te wā e kore e hiahiatia ki te hanga whenua.

kia whakahua hoki tatou i te puoro raorao-sigma pera-ka karanga, e te mea haepapa mo te taumata o te auau tauira. whakamana faafariuraa (quantization) te ki kotahi tiaki, i te mea tekau ara rau o nga wa ranei e taea te nui o te auau taketake Nyquist. Te tātari āwhiwhiwhi whakamahia i roto i tetahi o te atamira tohu faafariuraa, ā-rua huringa waehere raupapa mā te tāpiri ngā kore ki te awa raraunga iti-auau, me ngā waeine - no te auau tiketike.

Mai te nuinga o nga conductors he rua mōrahi kaha, me te urupare ka whakamatautau tika te anake tutuki, no te whakamahi i te aratau iti o te rere whakamuri, e heke te hiko o taura me, rite te tupu, - e tukupu haruru. I roto i te ara i te teka pānga kitā taea te hoatu hei tauira. mohio guitarists e te roa te taura i te rakuraku ki te "gadgets", te atu te papamuri. Tenei āhuatanga pai whakaatu te māramatanga o te mea i raro.

DAC ki te kawenga e taea te hono tika. Ko mo tenei ki kia whakamahia te pūrere atu pērā i te ngaohiko hei mahi amp Kōaro op rite moka Rite ranei ranei. I te wa ano e whakatutuki hoki te pātai o Tuhinga tetahi kaupapa. Me whakamahi te waihanga pae motuhake mō te wahi mamati me tairitenga, no te mea e taea e te ngangau i te wāhanga mamati whakaawe i te wahi tairitenga o te whatunga. tutuki tēnei mā te whakamahi i tētahi waea angiangi ranei te whakamahi i rua ngā papa rua ā-roto i te poka.

hei utu putanga

O te akoranga, i reira e te tahi mau parau tumu pūtaiao i whakaaro a tae noa take hangarau e te kaiwhakamahi mau i roto i te whānui, he reira tino maumau. Ko, i runga i whakaaro tuarua, i ētahi wā ariā o te matauranga e taea e tino whai hua. Ko te taua whānui o te kāri tangi kore e taea te mahi i waho te matauranga o nga āhuatanga matua e pā ana ki te mau parau tumu o tona mahi me te mahi tika o te pūnaha rorohiko.

Pea e kore i te tahi mau iwi ano te kitenga o e te tangi kounga rawakore o te kaikōrero, he pā ana tika ki te taputapu e whakamahia ana. Ko te kupu saundkarta whakamahia mō te tārua i te tohu mamati ului ki tona puka tairitenga, kia waiho ai anake te momo waho. Ko enei whakaaro tukua ki te whakarongo koe nga mea katoa ngātahi e te ranei e kore e pūrere tango tākaro. Kei te whakapono te reira i e i roto i te 80 ōrau o te wā, te raruraru e takoto ïa i roto i tenei. E te ara, e rave rahi ratonga rite iTunes, Spotify te tahi mea ranei atu, "whakakoi" tika i raro i te whakamahi o DACs. He teihana tāmau ara motuhake i roto i te puka o ngā pūrere waho hono ki tou iPod, e kore ki te whakahua i te tahi atu gadgets pūkoro.

haere te reira i waho e mea e kore ko reira te tūnga whakamutunga takaro e te pūnaha tukuoro taringa ranei, no te mea te tangi wāhanga noa i te kaikōrero, i te mau rave'a e whāiti āhuatanga tangi i te taumata o 20-10 000 Hz, he taea noa. Na reira, e kore kia whakamahia te nuinga o nga whakaaro i roto i te puka o taringa mō ngā pūnaha pūkoro. Ki te tae mai te reira ki taua, he aha e kore whakarongo ki te waiata ki te taringa K99, hangaia e te AKG, ranei te whakamahi i ngā pūrere rite i Sennheiser? Heoi, he nui te whiriwhiri i tenei ra nui.

Pera i te matara hangarau whakamātautau, kua oti nei te kōrero i runga ake, e kore e taea ki te kapo kahore hoki he matauranga i te iti rawa taketake o te ahupūngao ki te whakamārama i te āhua o ngaru oro, me tae noa engineering hiko, no te mea e whakarato tenei ako te anga ki te matau i roto i tetahi ara iahiko hiko. A, o te akoranga, i reira i hoatu noa ngā mōhiohio whakarāpopoto taketake e pā ana ki te pūtahuri tohu. Hei mahino kakato ange i runga i tenei take, he mea e minaminatia ki te pānui i tuhinga atu.
