Ngokuqinisekileyo uye wazibuza ngaphezu kwesihlandlo esinye: indlela isihogo ekwazi ngayo Shazam ukubona into edlalwayo kwaye uyenze ngokukhawuleza ngenani leengoma ezikuwo wonke umzi womculo? Ngokucacileyo, ayisiyiyo imilingo, nangona inkqubo ecingisiswe kakhulu kunye necacileyo emva kwayo iyenza ibonakale ngathi. Uyafuna ukwazi indlela esebenza ngayo? Ewe, ungaphoswa yividiyo elandelayo.
Usebenza njani uShazam, ukuya kwisigqi sikaJaime Altozano
Kusenokwenzeka ukuba sele umazi kodwa ukuba ubhaqwe, siyakuxelela ukuba uJaime Altozano ngumsasazi odumileyo waseSpain kunye ne-youtuber ono ijelo elaziwayo apho athetha ngomculo. Ewe kunjalo, akazinikezelanga ekuxeleleni ukuba ngawaphi amaqela omculo azithandayo okanye ukuphendula iiklip zevidiyo ezintsha ukwenza ubuso okanye ukwenza ingxabano; endaweni yoko, into ayenzayo, kwaye ngobuchule, kukuba cacisa indlela umculo osebenza ngayo, kutheni kukho iingoma esizifumana zinomtsalane okanye yintoni imfihlelo yesandi se-albhamu kakubi evela eRosalia okanye intshayelelo ye Umdlalo weTrone. Ekugqibeleni, isinceda sikuqonde oko sikuvayo.
Enkosi kwitshaneli yakhe unokufunda okuninzi malunga nobu bugcisa kwaye nokuba awuyiyo imvumi okanye ingcali kwintsimi (njengoko uJaime enjalo), yindlela emangalisayo yokufumanisa malunga nezinto ezininzi ezinxulumene nomculo oya kuthi ngokuqinisekileyo. ukufumana kuluncedo Ngowona mzekelo ubalaseleyo? Ividiyo yakhe yamva nje isebenza njani i-shazam.

Ukuyicacisa, uJaime uziseke kwi amaxwebhu apapashiweyo ngowakhe umdali waseShazam, Avery Wang, ongazange abe neentloni malunga nokwabelana nehlabathi ukuba i-algorithm emva komculo wakhe owaziwayo isebenza njani. Ukusuka apho, i-youtuber ijongene nokuguqulela ulwazi oluthethiweyo kulwimi olulula kakhulu kunye noluqondakalayo ngakumbi, nokusebenzisa inkxaso ye-lego pieces ukuze sibe nokuqonda kakuhle ingcamango-engeyiyo ncam. elula.
Kwimivumbo ebanzi kakhulu (kakhulu), into eyenziwe nguWang kukudala inkqubo ekwaziyo ukuhlalutya amanqaku aphambili ispectrogram yesandi (Fig. 1A -kule migca-) ye-audio erekhodwa yifowuni yakho, "yidlulise" kwigrafu (Fig. 1B) kwaye ufumane "umdlalo" wabo okanye ngenye indlela kwidatabase yayo enkulu ngesantya esikhawulezayo. Le nkqubo isekelwe kuhlobo "lweminwe yomsindo", exhaswa yidatha enemiba emithathu engundoqo: i-frequency erekhodiweyo kwi-second ethile yokurekhoda, i-frequency yesibini evale ixesha ukuya kwelokuqala, kunye nomgama phakathi kwabo. amaza (Fig. 1D).
Intloko yakho ivele yagqabhuka, akunjalo? Ungakhathazeki kwaye, ngokwenene, siphulaphule: xa ucinezela ukudlala kwaye ubone ividiyo kunye neziqwenga ze-LEGO, uya kuqonda yonke into. Ilizwi. Ngaphandle kokuphinda sikushiye kunye ne ingcaciso ebalaseleyo nguJaime Altozano malunga nendlela uShazam asebenza ngayo. Mhlawumbi xa ividiyo iphela awuyi kukwazi ukuvelisa kwakhona, kodwa ngokuqinisekileyo uya kuziva unobulumko obuncinci.
