MP3 → FLAC

Akunalutho, futhi kufanelekile ukuba kucace: akukho okuzokwenzeka. I MP3 idlulele i-detail ngesikhathi sokuqothula kwayo okujwayelekile, futhi ukubopha okushiwo ku FLAC ongeke ulahlekelwa yilutho kugcina lokho - akukho okuningi. Ihele lithola izikhathi eziningi ezikhulu futhi lizwakala lifana. 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-MP3 ihlukaniswe ngokukhethekile yi-AAC ne-Opus nganoma yisiphi isivinini se-bit, ingagcina ngaphezulu kwama-channels amabili ngokunembile, futhi ihlala ifaka ukulibazisa okuncane kwe-encoder.

Ngokuvamile akunjalo. MP3 i-decoded yinoma yini, kufaka phakathi izimoto eziphezulu nezidlali ezikhulu; FLAC idinga isofthiwe eyazi i-codec, esizohlala i-hardware ehlala ikhona. Uma indawo esiya kuyo imoto ye-stereo noma umdlali ophathekayo, lokhu kuyisinqumo esiqinile sokuhlala ku MP3. FLAC akazange ashintshe, futhi Apple's ecosystem kuphela engeza insizakalo okwamanje futhi grudgingly.

Iphutha 192 kbps ku FLAC olahlekelwayo; dlula-nge- FLAC ongalahlekelwayo. Nciphisa ku 320 kbps uma ufuna ubukhulu obuphezulu bokungathembeki okulahlekile, 128 kbps ku-podcast yokusabalalisa obukhulu-bulinganiselwe, noma 96 kbps ku-voice-only sources lapho ifayela elincane libalulekile kunemininingwane yestudio.

Uma MP3 ilahlekelwa (MP3, AAC) futhi FLAC ayilahlekelwanga (WAV, FLAC), FLAC ayingcono kuna MP3 — awukwazi ukubuyisela imininingwane elahlekile yi-MP3 codec elahlekile. Uma MP3 ayilahlekelwanga futhi FLAC ilahlekelwa, cabanga ukuthi i-FLAC encoder izocindezela futhi; ku-192 kbps ilahlekelwa ayikwazi ukubonwa yimilomo eminingi.

Yebo — isihloko, umculi, i-album, unyaka, inani le-track, i-album art, BPM, ukuphindeka-kwe-gain kufundeka kusuka ku MP3 ibhokisi futhi kubhalwe kuma-fields alinganayo ku FLAC ibhokisi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC, M4A), RIFF INFO (WAV), ama-iXML chunks wonke ama-maps ngokuhlanzekile. FLAC yi-Free Lossless Audio Codec, ifomethi evulekile kusukela ngo-2001 ecindezela ngaphandle kokususa isampula eyodwa.

Yebo — susa isibaya se MP3 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 amahlanu. Ukwakhiwa kwefolda kugcinwa kwi-ZIP yesingeniso.

Ngokungagqibekanga yebo (a 48 kHz MP3 ikhiqiza 48 kHz FLAC, a 44.1 kHz MP3 ikhiqiza 44.1 kHz FLAC). Ukusebenza kahle okuthile — isibonelo, ukusatshalaliswa kwe-96 kHz studio masters kuya ku-44.1 kHz FLAC ukushaya i-CD, noma ukusatshalaliswa kwe-22 kHz voicemail kuya ku-44.1 kHz FLAC — isilinganiso sesampula esiphansi sifaka ukusatshalaliswa kabusha kwekhwalithi ephezulu ye-SOX-style.

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku FLAC kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast) noma inani elijwayelekile. Lisetshenziswa uma liguqula amabhayisikobho ngezinga lokuphatha elihlukile ku FLAC dlala.

I-MP3 idlala ngokugcwele kuwo wonke amadivayisi ayenziwe eminyakeni edlule engu-20. I-AAC idlala ku-Apple, ku-Android, ku-Sonos, nama-stereo emoto yamanje. I-FLAC idlala ku-Sonos ne-Android edlule, ingcono kakhulu kuma-iPods adala. I-WAV idlala kuwo wonke amadivayisi kodwa ifayela likhulu. I-idivayisi-yesihluthulelo sokukhuphuka ikhetha i-FLAC codec ephephile ye-platform oyicacisile.

Yebo — amafayela alayishwe phezulu MP3 aphathwa ngabasebenzi abahlukanisiwe futhi asuswa emizuzwini. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe kwesandi. Ipayipi lisebenza ngehardware esilawula ngayo kusukela ekuqaleni kuya kukuphela; akukho inkonzo yeqembu lesithathu ethola ifayela lakho.

I-codec efanayo iphinde i-mux (isibonelo AAC ngaphakathi M4A -> AAC ngaphakathi MP4): imizuzwana engu-10-30. Ushintsho lwe-codec (isibonelo FLAC -> MP3 noma WAV -> AAC): ngokuvamile 10-20% yomthombo wesikhathi, ngakho-ke ihora MP3 -> FLAC liphele ngemizuzu engu-6-12 ku-pipeline ejwayelekile.
