MP3 kuya MP2 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo MP3 ube MP2 ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele MP3 futhi umguquli ukhetha MP2 i-codec / i-bitrate ehambisana neprofayili yomsuka. I-lossless MP2 (WAV / FLAC / ALAC) igcina yonke isampula ngokugcwele; i-lossy MP2 (MP3 / AAC / OGG / Opus) iphutha liyi-192 kbps ecacile kakhulu kunoma iyiphi ingxenye yomculo. MP3 ilahlekelwa: imodeli ye psychoacoustic isusa iziqongo ezingezona ezivamile, ezivame ukuba ngu-128 kuya ku-320 kbps. MP2 ilahlekelwa yinto kodwa isebenzisa isihlungi esilula kunaso iMP3, isebenza nge 192 kuya ku 384 kbps.

Ingabe ukushintsha MP3 kuya ku MP2 kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-MP2 encoder isebenza kusuka kumsindo osele udlulele engxenyeni eyodwa ye-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-MP2 kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele.

Ingabe izihloko zengoma yami nesithombe se-albhamu sizohlala isikhathi eside uma ngishintsha MP3 kuya ku MP2?

Akulungile. MP3 ifaka i-metadata efanele, kodwa MP2 ayinaso isikhala esijwayelekile somuntu oculi, i-album, inani le-track noma umhlobiso we-cover, ngakho-ke amathegi asuswa ngaphandle kokulahleka. Gcina i-MP3 njengekhophi elabelwe, noma uphinde ubeke i-tag ngemuva ngethuluzi njenge Mp3tag noma MusicBrainz Picard. I-MP2 idinga i-bitrate engaphezulu kune-MP3 noma i-AAC ukuze ibe nekhwalithi efanayo futhi ayiziwa kusoftware eminingi yomsebenzisi.

Ihele MP2 liphele nini nge-bitrate?

Iphutha 192 kbps ku MP2 olahlekelwayo; dlula-nge- MP2 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.

Ingabe ukusuka ku MP3 kuya ku MP2 kuzonciphisa kakhulu izinga lami lomsindo?

Uma MP3 ilahlekelwa (MP3, AAC) futhi MP2 ayilahlekelwanga (WAV, FLAC), MP2 ayingcono kuna MP3 — awukwazi ukubuyisela imininingwane elahlekile yi-MP3 codec elahlekile. Uma MP3 ayilahlekelwanga futhi MP2 ilahlekelwa, cabanga ukuthi i-MP2 encoder izocindezela futhi; ku-192 kbps ilahlekelwa ayikwazi ukubonwa yimilomo eminingi.

Ingabe i-MP3 kuya ku-MP2 igcina amathegi we-ID3 / metadata?

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 MP2 ibhokisi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC, M4A), RIFF INFO (WAV), ama-iXML chunks wonke ama-maps ngokuhlanzekile. MP2 yi MPEG-1 Audio Layer II, i-layer edlule i-MP3 futhi yabe yi-audio standard ye-DVB ne-DAB broadcasting.

Ingabe ngingenza ukuguqulwa kwekhulu le MP3 amafayela abe MP2?

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.

Ingabe i-MP2 izogcina isilinganiso esifanayo sesampula njenge-MP3?

Ngokungagqibekanga yebo (a 48 kHz MP3 ikhiqiza 48 kHz MP2, a 44.1 kHz MP3 ikhiqiza 44.1 kHz MP2). Ukusebenza kahle okuthile — isibonelo, ukusatshalaliswa kwe-96 kHz studio masters kuya ku-44.1 kHz MP2 ukushaya i-CD, noma ukusatshalaliswa kwe-22 kHz voicemail kuya ku-44.1 kHz MP2 — isilinganiso sesampula esiphansi sifaka ukusatshalaliswa kabusha kwekhwalithi ephezulu ye-SOX-style.

Ingabe ngizolungisa umsindo ku-MP3 kuya ku-MP2?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku MP2 kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast) noma inani elijwayelekile. Lisetshenziswa uma liguqula amabhayisikobho ngezinga lokuphatha elihlukile ku MP2 dlala.

Ingabe i-MP2 izodlala ku-stereo yemoto yami / iPod / Sonos / isikhulumi se-Bluetooth?

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-MP2 codec ephephile ye-platform oyicacisile. MP2 inamandla amakhulu kakhulu ukuxazulula amaphutha ancane futhi ibiza kakhulu ukuwususa, ngakho-ke izintambo zokusakaza zihlala kuyo isikhathi eside ngemuva kokufika kweMP3.

Ingabe ihele lami MP3 liyimfihlo ngesikhathi sokuguqulwa?

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.

Ingabe kuthatha isikhathi esingakanani ukushintsha ihora le-MP3 libe MP2?

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 -> MP2 liphele ngemizuzu engu-6-12 ku-pipeline ejwayelekile.

MP3

Amafayela e-MP3 asebenzisa ukucindezela okulahlekile ukunciphisa usayizi wefayela ngenkathi kugcinwa ikhwalithi yomsindo eyamukelekayo kubalaleli abaningi.
