Riffusion-projektet udvikler en variant af Stable Diffusion maskinl\u00e6ringssystemet, tilpasset til at generere musik i stedet for billeder. Musik kan syntetiseres ud fra tekstbeskrivelser p\u00e5 naturligt sprog eller baseret p\u00e5 et foresl\u00e5et skabelon. Komponenterne til musiksyntesen er skrevet p\u00e5 Python ved hj\u00e6lp af PyTorch-rammen og er tilg\u00e6ngelige under MIT-licensen. Interfacesystemet er implementeret i TypeScript og leveres ogs\u00e5 under MIT-licensen. De tr\u00e6nte modeller er \u00e5bne under den tilladende Creative ML OpenRAIL-M-licens, der tillader kommerciel brug. <\/p>\n

Projektet er interessant, fordi det forts\u00e6tter med at bruge modeller til musikgenerering fra «tekst til billede» og «billede til billede», men bruger spektrogrammer som billeder. Med andre ord er den klassiske Stable Diffusion tr\u00e6net ikke p\u00e5 fotografier og billeder, men p\u00e5 billeder af spektrogrammer, der afspejler \u00e6ndringen i frekvens og amplitude af lydb\u00f8lgen over tid. Som f\u00f8lge heraf dannes der ogs\u00e5 et spektrogram som output, som derefter omdannes til en lydrepr\u00e6sentation.

\"Stable<\/center> <\/p>\n

Metoden kan ogs\u00e5 bruges til at \u00e6ndre eksisterende musiknumre og syntetisere musik baseret p\u00e5 en skabelon, p\u00e5 samme m\u00e5de som billeder modificeres i Stable Diffusion. For eksempel kan der gives eksempler p\u00e5 spektrogrammer med en reference stil under genereringen, kombinere forskellige stilarter, lave glidende overgange fra en stil til en anden eller \u00e6ndre eksisterende lyd for at l\u00f8se opgaver som at \u00f8ge lydstyrken af enkelte instrumenter, \u00e6ndre rytmen og skifte instrumenter. Eksempler bruges ogs\u00e5 til at generere langvarige kompositioner, der er sammensat af en serie af n\u00e6rtliggende sektioner, som lidt \u00e6ndrer sig over tid. Individuelt genererede sektioner samles til et kontinuerligt flow ved hj\u00e6lp af interpolation af de indre modelparametre.

\"Stable<\/center> <\/p>\n

For at skabe et spektrogram fra lyd anvendes vindue-transformasjonen Fourier. Ved rekonstruktion af lyd fra spektrogrammet opst\u00e5r der et problem med at bestemme fasen (spektrogrammet indeholder kun frekvens og amplitude), hvilket kr\u00e6ver en algorithmisk tiln\u00e6rmelse af Griffin-Lima.
