Mapurogiramu anoona nziyo anoshanda sei, saShazam?

Shazam nekambani yave imwe yeaya anoshamisa maapplication atinogona kutakura pane smartphone. Uye hakusi kuti havana mukurumbira, nokuti munhu wose anotovaziva, asi zvichiri kuratidzika semashiripiti kuti vanokwanisa kuziva rwiyo rwuri kutamba chero nguva ipi zvayo. Ngationei kuti mapurogiramu akaita seShazam anoshanda sei chaizvo.

Spectrography, mbiru inokosha

Muchokwadi, maapplication aya anobva pane zvatinoziva se spectrography, kana spectroscopy, kureva, muviri weruzivo une chekuita nekuongorora kwe spectroscopic. Uye nemashoko aya zvinogona kunetsa kunzwisisa asi tichazvitsanangura nechinguva chidiki. Kana ruzha rupi norupi rwunobudiswa, tinorunzwa nokuti mativi ari pakati pedu nekwanobva inzwi iroro anofamba, anodedera. Kana tichiti zvidimbu izvi zvinofamba, tinoreva kuti zvinogadzira masaisai, anobva pane imwe nzvimbo achienda kune imwe. Nhamba yenguva dzinofamba zvidimbu izvi zvichidzoka shure zvinodaidzwa kuti frequency, uye chokwadi tese takanzwa nezve frequency yeruzha, handiti? Zvakanaka, spectrography, munyaya iyi, yakatsaurirwa kuyera kuwanda kwemanzwi mune imwe nguva yenguva. Ruzha rumwe nerumwe rune frequency yakasiyana panguva imwe neimwe, uye izvo zvinotibvumira kusiyanisa, pane spectrogram, iyo inonzwika inonzwika.

Zvose inyaya yekuenzanisa

Unoziva sei rwiyo rwuri kuridzwa? Kuenzanisa. Kutaura zvazviri, zvakafanana nokutora “X-ray” woienzanisa nemamwe ma<em>X-ray emanzwi atainge tambochengeta, nokudaro tichikwanisa kuziva kuti ndeupi pazvose unofanana neicho. Zvakanaka, aya ndiwo mashandiro anoita Shazam nemamwe maapplication.

Shazam inonzi spectrograph

Patinotanga Shazam, uye inotitaurira kuti iri kuziva rwiyo, izvo zvauri kuita chaizvo kushandura smartphone yedu kuita spectrograph. Iko kutora ruzha uye kugadzira spectrogram seyauinayo pamusoro peiyi ndima. Paunenge uchinge uine yakakwana yakadzama spectrograph, wobva waenderera mberi nekuienzanisa neiyo yese database yavakachengeta.

Database ndiyo yakanyanya kuoma

Muchokwadi, iyo yakanyanya kuomarara pane yese dhatabhesi inochengeta ma spectrogram enziyo dzese. Isu tinoziva kuti zvakaoma sei kugadzira sevhisi yemimhanzi ine mimhanzi yese munyika. Spotify ndechimwe chezvirongwa izvi, asi nziyo dzakakosha dzichiri kushaikwa kubva pazviri. Zvakanaka, kana izvo zvatove zvakaoma, fungidzira kuti zvinofanirwa kunge zvakaita sei kuchengeta ma spectrogram enziyo dzese idzi. Zvakajairika kuti chikamu chebasa rechikwata cheShazam uye mamwe maapplication akafanana kuzvipira kuwedzera dhatabhesi iro, chokwadi, ndiro moyo wechishandiso.

Kushanda kwayo pasina Indaneti kuri nyore

Dzimwe nguva isu tinogona kushamisika kuti maapplication aya anogona kushanda sei kunze kwenyika, pasina chinongedzo cheInternet. Izvo zviri nyore kwazvo, sezvo ivo vasingambotipa iyo data kudzamara vabatana neInternet. Ivo havafanirwe kuchengetedza rwiyo rwese, havafanirwe kana kuchengetedza chidimbu chemimhanzi chatinoda kuongorora. Muchokwadi, chinhu chega chavanochengeta ndeye spectrographic data, kuitira kuti gare gare ivo vakwanise kuenzaniswa mudhatabhesi, uye izvo zvinotora chero chinhu.

Iyo algorithm yakakosha

Nekudaro, chimwe chezvakanyanya kukosha zvezvishandiso izvi ndeye algorithm yavanoshandisa kuenzanisa nziyo. Algorithm, muchokwadi, haisi chimwe chinhu kunze kwenzira yekuita maitiro. Shazam's algorithm inofanira kugara ichivandudza. Sei? Nekuti ivo vanofanirwa kushanda kuti sisitimu itevere nzira inobvumira kuti iwane rwiyo nekukurumidza. Uye ndezvekuti munhu anogona kufunga kuti kana ma spectrograms akanzwisiswa uye dhatabhesi renziyo rakapedzwa, zvese zvinoitwa, asi hapana chinowedzera kubva pachokwadi. Ngatifungei kuti unofanira kuenzanisa spectrogram nemamiriyoni nemamiriyoni enziyo. Nekudaro, iyo algorithm ndechimwe chezvinhu zvikuru. Pane nzira dzakawanda dzemakombuta dzekuvandudza izvi, uye hatisi kuzotaura nezve chero ipi zvayo nekuti zvingaite sekutaura nezvechimiro cheMakore pazuva rine dutu. Nekudaro, zvinogara zvakanaka kuziva kuti iyo algorithm yechishandiso chimwe chezvinhu zvakakosha, pamwe neiyo spectrography basa, uye iyo yenziyo dhatabhesi.
