MP3 ukuba MP2 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-MP3 yesandi ibe yi-MP2 ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili MP3 kwaye umguquli ukhetha MP2 i-codec / uthelekiso lwe-bitrate oluhambelana neprofayili yombhali. I-lossless MP2 (WAV / FLAC / ALAC) igcina yonke isampuli ngokuchanekileyo; i-lossy MP2 (MP3 / AAC / OGG / Opus) imiselwe kwi-192 kbps ebonisa ngokucacileyo imixholo yonke yengoma. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps. MP2 ilahlekile kodwa isebenzisa ibanki yecebo lokucoca ulwelo elilula kune MP3, eqhelekileyo isebenza kwi 192 ukuya kwi 384 kbps.

Ingaba ukutshintsha MP3 ukuya ku MP2 kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i MP2 encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i MP2 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

Ingaba izihloko zam zengoma kunye nemifanekiso ye-albham iya kuqhubeka iphila kwi MP3 ukuya kwi MP2 uguqulo?

Ayiqhelekanga. MP3 ihambisa i-metadata efanelekileyo, kodwa MP2 ayinandawo eqhelekileyo yomsebenzi womculi, i-albham, inani lengoma okanye ubugcisa besiqhoboshelo, ngoko ke iimpawu zilahliwe endaweni yokulahleka. Gcina i MP3 njengekopi ephawulweyo, okanye uphinde uphawule emva koko ngesixhobo njenge Mp3tag okanye iMusicBrainz Picard. I-MP2 ifuna i-bitrate engaphezulu kune-MP3 okanye i-AAC yomgangatho ofanayo kwaye ayiziwa kuninzi lweenkqubo zomsebenzisi.

I-MP2 ifayili iphela kwi-bitrate enjani?

Okumiselweyo 192 kbps kulahleko MP2; dlula-kwi-lossless MP2. Nciphisa ukuya kwi-320 kbps ukuba ufuna ubukhulu bokungazinzi okulahlekileyo, 128 kbps kunikezelo lwepodcast olukhawulezayo, okanye 96 kbps kumthombo welizwi kuphela apho ifayili encinci ibalulekile ngakumbi kuneenkcukacha zestudio.

Ingaba ukuya ukusuka kwi MP3 ukuya kwi MP2 kuya kunciphisa ubunjani besandi sam?

Ukuba MP3 ilahlekile (MP3, AAC) kwaye MP2 ayilahleki (WAV, FLAC), i MP2 ayingcono kune MP3 — awunakubuyisela ulwazi olusele lulahlekile yi-MP3 codec. Ukuba i MP3 ayilahleki kwaye MP2 iyalahleka, lindele ukuba i MP2 encoder iphinde icinezele; kwi-192 kbps ilahleko ayifumaneki kuninzi lweendlebe.

Ingaba i-MP3 ukuya kwi-MP2 igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi MP3 isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi MP2 isiqulathi seefayili. ID3v2 (MP3), i-Vorbis impendulo (OGG, FLAC), i-MP4 ii-atoms (AAC, M4A), RIFF INFO (WAV), i-iXML i-chunks zonke iimaphu ngokucocekileyo. I-MP2 yi-MPEG-1 Umphezulu Womsindo II, umphezulu ongaphambili kwe-MP3 wavela waba ngumlinganiselo womgangatho womfanekiso we-DVB kunye ne-DAB yosasazo.

Ndingaguqula izigidi zeefayili MP3 zibe MP2?

Ewe - susa isiqulathi seefayili se MP3 kwifayile kwaye siziqhubekeke ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10s yemizuzu. Ukwakhiwa kwesiqulathi seefayili kugcinwa kwimveliso ye-ZIP.

Ingaba i-MP2 iya kugcina inqanaba lesampuli elifanayo njenge-MP3?

Ngokungagqibekanga ewe (a 48 kHz MP3 ivelisa 48 kHz MP2, a 44.1 kHz MP3 ivelisa 44.1 kHz MP2). Ukulungelelanisa okuthile — umzekelo, ukunyusa isampuli ye-96 kHz studio masters ukuya kwi-44.1 kHz MP2 yokukhupha i-CD, okanye ukunyusa isampuli ye-22 kHz yeposi yelizwi ukuya kwi-44.1 kHz MP2 — isampuli-ixabiso lokuhla lisebenzisa umgangatho ophezulu we-SOX-style resamply.

Ndingazilungisa njani ilizwi kwinyathelo MP3 ukuya kwi MP2?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye MP2, ibeka i- -14 LUFS (isiqhelo sokusasaza) okanye i- -16 LUFS (isiqhelo sepodcast) okanye ixabiso elimiselweyo. Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo kwi-MP2 yoluhlu lokudlala.

Ingaba i-MP2 iya kudlala kwi-stereo yemoto yam / i-iPod / i-Sonos / isithethi se-Bluetooth?

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esiyenziwe kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, i-Sonos, kunye ne-stereo zemoto zakudala. I-FLAC idlala kwi-Sonos ne-Android ekutshanje, isebenza kakubi kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ifayili ikhulu. Isixhobo-esimiselweyo esithe tyaba sikhetha i-MP2 codec ekhuselekileyo ye-platform ocacisayo. I-MP2 inamandla kakhulu ekuphumezeni iimpazamo ze-bit kwaye ibiza kakhulu ukuyikhupha, oko kubangela ukuba iinqanawa zokusasaza zihlale kuyo ixesha elide emva kokuba i-MP3 ifike.

Ingaba ifayili yam MP3 ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu MP3 ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo yesandi. Inkqubo yokuhambisa iqhuba kwihardware esilawulayo ukusuka ekuqaleni ukuya kwisiphelo; akukho nkonzo yeqela lesithathu ifumana ifayili yakho.

Ithatha ixesha elingakanani ukutshintsha i-MP3 yeyure enye ibe yi-MP2?

I-codec efanayo yoku-multiplex (umzekelo. AAC ngaphakathi kwe-M4A -> AAC ngaphakathi kwe-MP4): imizuzwana eyi-10-30. Utshintsho lwe-codec (umzekelo. FLAC -> MP3 okanye WAV -> AAC): ngokuqhelekileyo i-10-20% yobude bomthombo, ngoko ke i-1-iyure MP3 -> MP2 igqiba kwimizuzu eyi-6-12 kwinkqubo eqhelekileyo yokuhambisa.

MP3

Iifayile zeMP3 zisebenzisa ucinezelo olulahlekileyo ukunciphisa ubungakanani befayile ngelixa zigcina umgangatho wesandi owamkelekileyo kubaphulaphuli abaninzi.
