AIFF ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili AIFF kwaye umguquli ukhetha MP3 i-codec / uthelekiso lwe-bitrate oluhambelana neprofayili yombhali. I-lossless MP3 (WAV / FLAC / ALAC) igcina yonke isampuli ngokuchanekileyo; i-lossy MP3 (MP3 / AAC / OGG / Opus) imiselwe kwi-192 kbps ebonisa ngokucacileyo imixholo yonke yengoma. I-AIFF igcina i-PCM engacinezelwanga encinci-ephakathi — i-Apple-side elinganayo ne-WAV, nge-bit-per-bit fidelity efanayo. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ingaba ndilahlekelwe yintoni ngokuguqula i AIFF ibe yi MP3?

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. AIFF igcina yonke imilinganiselo ngokuchanekileyo; MP3 isusa into eyenza imodeli ye psychoacoustic ilindele ukuba awuzukuyiva. Kwi 192 kbps nangaphezulu loo lindeleko kulungile ngokwaneleyo ukuba icacile kwizinto ezininzi nezixhobo ezininzi. Gcina i AIFF njengenkosi yakho, kuba awunakubuyela kuyo ukusuka kwi MP3.

Ithini into ebangela ukuba i-multichannel yesandi iguqulwe kwi AIFF ukuya kwi MP3?

Ijika ezantsi kwi-stereo, kuba MP3 ayinayo indlela esebenzayo ye-multichannel. Ukudibanisa ezantsi kusetyenziswa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-ndawo zidityanisiwe kwinqanaba eliphantsi. Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo iphela xa oku kwenzeka. MP3 igqityiwe nge AAC ne Opus kwinqanaba ngalinye le-bitrate, ayikwazi ukugcina ngaphezulu kweendawo ezimbini eziluncedo, kwaye ihlala idibanisa ulibaziso oluncinci lwe-encoder.

I-MP3 ifayili iphela kwi-bitrate enjani?

Okumiselweyo 192 kbps kulahleko MP3; dlula-kwi-lossless MP3. 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 AIFF ukuya kwi MP3 kuya kunciphisa ubunjani besandi sam?

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

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi AIFF isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi MP3 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-MP3 yi-MPEG-1 Umphezulu Wosandi III, egqityiwe ngo-1993, kwaye ihlala i-format yesandi ekwazi ukucoda ngokupheleleyo ekhoyo.

Ndingaguqula izigidi zeefayili AIFF zibe MP3?

Ewe - susa isiqulathi seefayili se AIFF 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-MP3 iya kugcina inqanaba lesampuli elifanayo njenge-AIFF?

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

Ndingazilungisa njani ilizwi kwinyathelo AIFF ukuya kwi MP3?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye MP3, ibeka i- -14 LUFS (isiqhelo sokusasaza) okanye i- -16 LUFS (isiqhelo sepodcast) okanye ixabiso elimiselweyo. Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo kwi-MP3 yoluhlu lokudlala.

Ingaba i-MP3 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-MP3 codec ekhuselekileyo ye-platform ocacisayo. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

Ingaba ifayili yam AIFF ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu AIFF 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-AIFF yeyure enye ibe yi-MP3?

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 AIFF -> MP3 igqiba kwimizuzu eyi-6-12 kwinkqubo eqhelekileyo yokuhambisa.

AIFF

I-AIFF (i-Audio Interchange File Format) yifomathi yefayile yeaudio engaxinzelelwanga edla ngokusetyenziswa kwimveliso yomsindo kunye nomculo.

MP3

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