Isinyathelo sokukhiqiza zonke izinhlobo zamaringithoni ukuze uvikeleke ekuphulwa kwe-copyright

U-Damien Riehl, ummeli, umdidiyeli kanye nomculi, no
umculi uNowa Rubin wazama misa amacala okuphulwa kwe-copyright esikhathini esizayo ahlobene nezinsolo zokukopela umculo. Ukuze kusetshenziswe lo mbono, kwakhiqizwa uchungechunge olukhulu lwemiculo ye-MIDI, amalungelo okushicilela atholwa ale miculo ezenzakalelayo, kwase kuthi imiculo yadluliselwa esizindeni somphakathi.

Umqondo uwukuthi umculo ungacatshangwa njengezibalo futhi kunenani elilinganiselwe lemiculo engenzeka. Uma ezinye izingoma zibonakala zifana, lokhu akukhona ukukopela ngaso sonke isikhathi, kodwa mhlawumbe ukuqondana okungahleliwe ngenxa yenani elilinganiselwe lemiculo engenzeka kanye nokungagwemeki kokuphindaphinda. Ngokuhamba kwesikhathi, kunezingoma zomculo ezikhulayo, futhi esikhathini esizayo kuzoba nzima ukuthola izingoma eziyingqayizivele ezingakaze zihlangane nazo ngaphambili.

Ukukhiqiza nokushicilela yonke imiculo engenzeka ukuze isetshenziswe mahhala kuzovikela abaculi ezimangalweni zesikhathi esizayo zokwephulwa kwe-copyright, njengoba enkantolo kuzokwazi ukukhombisa iqiniso lokudalwa kwangaphambilini komculo othile kanye nokusatshalaliswa kwawo ukuze kusetshenziswe ngokungenamkhawulo. Ukwengeza, uma sibheka imiculo njengokuvumelana kwedijithali okunqunywe kusengaphambili okukhona kusukela ekuqaleni, kungase kwenzeke ukufakazela ukuthi imiculo ihlobene nezibalo futhi amaqiniso nje angekho ngaphansi kwelungelo lobunikazi.

Ababhali bephrojekthi bazama nge-algorithmically ukunquma yonke imiculo engaba khona equkethwe i-octave eyodwa. Ukukhiqiza imiculo kwadalwa i-algorithm, erekhoda izinhlanganisela zemiculo enanothi angu-8 nebhithi engu-12 isebenzisa iqhinga lokuzama zonke izinhlanganisela ezingaba khona, ezifana nokuqagela ama-hash ephasiwedi. Ukuqaliswa kwe-algorithm kwenza kube nokwenzeka ukukhiqiza imiculo engaba yizinkulungwane ezingama-300 ngomzuzwana. Ikhodi yejeneretha yomculo ibhalwe ku-Rust kanye eshicilelwe ku-GitHub ngaphansi kwelayisensi ye-Creative Commons Attribution 4.0. Umculo ungathathwa njengone-copyright uma usugcinwe kufomethi edlalekayo njenge-MIDI.
Ingobo yomlando eseyenziwe kakade yezingoma ezikhiqiziwe (1.2 TB ku-MIDI) okuthunyelwe Kungobo yomlando ye-inthanethi njengesizinda somphakathi.
