AAC kuya Opus Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo AAC ube Opus ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele AAC futhi umguquli ukhetha i-Opus codec ne-bitrate ukufana nomsuka. Ukungabi naphutha Opus (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho Opus (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-Opus iqala ngokukhuluma kusuka ku-6 kbps mono speech kuya ku-510 kbps stereo music ku-bitstream efanayo futhi ishintsha indlela ngokuzenzakalela.

Ingabe ukushintsha AAC kuya ku Opus kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela.

Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-Opus kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele.

Ingabe ukusuka ku AAC kuya ku Opus kuzonciphisa ubunjani bomsindo wami?

Uma AAC ilahlekelwa futhi Opus ayilahleki (isibonelo MP3 → WAV), Opus ayingcono kuna AAC — awukwazi ukubuyisela imininingwane elahlekile. Uma AAC ilahlekelwa futhi Opus ayilahleki, i-Opus codec icindezela futhi; ku-192 kbps imiphumela icacile kunoma iyiphi ingxenye.

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, nesithombe se-album zifundwa kusuka ku AAC isitoreji futhi zibhalwe ku Opus isitoreji lapho ifomu lixhasa amathegi. Zonke izimo ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha amathegi kahle; i-WAV engaqondakali ayisebenzi. Opus kuyinto IETF standard kusukela 2012 ukuthi wahlanganisa Skype SILK ulwimi codec ne Xiph CELT music codec eyenziwe eyodwa.

Ingabe ngingenza i-batch yokuguqula amahele angama-AAC abe Opus?

Yebo — susa isibaya se AAC amafayela ngaphakathi futhi sizoziphatha ngokufanayo. I-Premium inemisebenzi eminingi efana ne-parallel futhi akukho lutho oluphezulu lwesayizi yefayela ngalinye, ngakho-ke i-500-file batch iphele ngemizuzu endaweni yamahora angama-10.

Ingabe i-Opus izogcina isilinganiso esifanayo sesampula njenge-AAC?

Ngephutha yebo — 48 kHz AAC ihlala 48 kHz ku Opus. Uma ufuna ukusatshalaliswa ngezansi ukuze kusebenze (96 kHz → 44.1 kHz ukushaya i-CD), isinqumo sesampula-sayizi sifaka ukusatshalaliswa okusezingeni eliphezulu kuleyo ngxenye yokungenisa ikhodi.
