Ngiguqula kanjani umsindo AAC ube FLAC ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele AAC futhi umguquli ukhetha i-FLAC codec ne-bitrate ukufana nomsuka. Ukungabi naphutha FLAC (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho FLAC (MP3 / AAC / OGG / Opus) kumiswa ku-192 kbps okucacile kuma-earphones amaningi. I-AAC ilahlekelwa yizinto kodwa isebenza kahle kunayo i-MP3, futhi iphatha kuze kube yi-48 channels ngokusemthethweni ngaphezu kokuboshwa ku-stereo design. I-FLAC isebenzisa ukubikezela okuqondile kanye nokuhlelwa kwe-Rice ukufinyelela cishe ku-50-60% wesayizi yangempela ngesikhathi sokuhlelwa emuva kwe-PCM efana ne-bit.

Kukhona ukunyakaza okulungile ngaphambi kokuhlela, ngoba FLAC ngeke ihlanganise isizukulwane sesithathu sezinto ezibonakalayo uma ukhipha. I-FLAC ikunikeza ukuthembeka kwe-WAV kungxenyekazi yesayizi, nge-metadata efanele kanye ne-artwork efakwe, ngakho-ke ilawula ama-library omculo angeke alahlekelwa. I-AAC ifakwe ipatenthi, futhi ama-players amasha ambalwa angeke avumeleke lapho befuna khona uku accetta i-MP3.

Ingabe i-FLAC izodlala emoto yami noma ku-hardware edala?
