Zizenza kanjani izinhlelo zokusebenza ezibona izingoma, njenge-Shazam?

I-Shazam nenkampani isibe enye yalezo zinhlelo zokusebenza ezimangalisa kakhulu esingaziqhuba ku-smartphone. Futhi akukhona ukuthi abadumile, ngoba wonke umuntu uyazi kakade, kodwa kubonakala sengathi cishe umlingo ukuthi bayakwazi ukuqaphela ukuthi iyiphi ingoma edlala nganoma yisiphi isikhathi. Ake sibone ukuthi izinhlelo zokusebenza ezifana ne-Shazam zisebenza kanjani ngempela.

I-Spectrography, insika ebalulekile

Eqinisweni, lezi zinhlelo zokusebenza zisekelwe kulokho esikwazi njenge-spectrography, noma i-spectroscopy, okungukuthi, indikimba yolwazi ehlobene nokuhlaziywa kwe-spectroscopic. Futhi ngala mazwi kungaba nzima ukuwaqonda kodwa sizokuchaza ngomzuzwana. Lapho kukhiqizwa noma yimuphi umsindo, siyawuzwa ngoba izinhlayiya eziphakathi kwethu nomthombo walowo msindo ziyanyakaza. Uma sithi lezi zinhlayiya ziyanyakaza, sisuke sisho ukuthi zikhiqiza amagagasi, asuka kwenye indawo aye kwenye. Inombolo yezikhathi lezi zinhlayiya ezihamba phambili naphambili ibizwa ngokuthi i-frequency, futhi ngokuqinisekile sonke sizwile ngokuvama komsindo, akunjalo? Nokho, i-spectrography, kulokhu, inikezelwe ekulinganiseni imvamisa yemisindo esikhathini esithile. Umsindo ngamunye unemvamisa ehlukile ngesikhathi ngasinye, futhi lokho kusivumela ukuthi sihlukanise, ku-spectrogram, imisindo ezwakalayo.

Konke kuyindaba yokuqhathanisa

Wazi kanjani ukuthi iyiphi ingoma edlalayo? Ukuqhathanisa. Empeleni, kufana nokuthatha "i-X-ray" bese uyiqhathanisa neminye imisindo yama-X esesivele siyigcinile, ngaleyo ndlela sikwazi ukwazi ukuthi iyiphi phakathi kwayo yonke efana naleyo. Hhayi-ke, iyona kanye indlela i-Shazam nezinye izinhlelo zokusebenza ezisebenza ngayo.

I-Shazam iyi-spectrograph

Uma siqala i-Shazam, futhi isitshela ukuthi iyayibona ingoma, empeleni ekwenzayo ukuguqula i-smartphone yethu ibe yi-spectrograph. Ithwebula umsindo futhi ikhiqize i-spectrogram efana nale onayo ngenhla nje kwalesi sigaba. Uma usune-spectrograph enemininingwane eyanele, bese uqhubeka ukuyiqhathanisa nayo yonke imininingwane egciniwe abayigcinile.

Isizindalwazi siyinkimbinkimbi kakhulu

Empeleni, inkimbinkimbi kunazo zonke isizindalwazi esigcina ama-spectrogram azo zonke izingoma. Siyazi ukuthi kunzima kangakanani ukudala isevisi yomculo equkethe wonke umculo emhlabeni. I-Spotify ingenye yalezo zinhlelo, kodwa izingoma ezibalulekile azikatholakali kuyo. Hhayi-ke, uma lokho sekuvele kuyinkimbinkimbi, cabanga ukuthi kufanele kube njani ukugcina ama-spectrogram azo zonke lezo zingoma. Kuvamile ukuthi ingxenye yomsebenzi wethimba le-Shazam nezinye izinhlelo zokusebenza ezifanayo ukuzinikezela ukwandisa i-database, empeleni, inhliziyo yohlelo lokusebenza.

Ukusebenza kwayo okungaxhunyiwe ku-inthanethi kulula kakhulu

Kwesinye isikhathi singase sizibuze ukuthi lezi zinhlelo zokusebenza zingasebenza kanjani ungaxhunyiwe ku-inthanethi, ngaphandle koxhumano lwe-inthanethi. Empeleni kulula kakhulu, njengoba bengasiniki idatha baze baxhumeke ku-inthanethi. Akudingeki ukuthi bayigcine yonke ingoma, abadingi nokuthi bagcine ucezu lomculo esifuna ukuwuhlaziya. Eqinisweni, into kuphela abayigcinayo idatha ye-spectrographic, ukuze kamuva iqhathaniswe ku-database, futhi lokho akuthathi lutho.

I-algorithm ibalulekile

Nokho, esinye sezici ezibaluleke kakhulu zalezi zinhlelo zokusebenza i-algorithm eziyisebenzisayo ukuqhathanisa izingoma. I-algorithm, empeleni, ayilutho nje kuyindlela yokwenza inqubo. I-algorithm ye-Shazam kumele ihlale ithuthuka. Kungani? Ngoba kumele basebenzele ukwenza uhlelo lulandele indlela evumela ukuthi ithole ingoma ngokushesha okukhulu. Futhi kungukuthi umuntu angacabanga ukuthi uma ama-spectrograms eqondwa futhi isizindalwazi sengoma sesiphelile, konke kwenziwa, kodwa akukho lutho olusuka eqinisweni. Ake sicabange ukuthi kufanele uqhathanise i-spectrogram nezigidi nezigidi zezingoma. Nokho, i-algorithm ingenye yezici eziyinhloko. Kunamasu amakhompiyutha amaningana okuthuthukisa lokhu, futhi akukho esizokhuluma ngakho ikakhulukazi ngoba kuzofana nokukhuluma ngesimo samafu ngosuku olunesiphepho. Kodwa-ke, kuhlale kukuhle ukwazi ukuthi i-algorithm yohlelo lokusebenza ingenye yezinto ezibalulekile, kanye nomsebenzi we-spectrography, kanye nalowo wesizindalwazi sengoma.
