MP3 ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili MP3 kwaye umguquli wethu ukhetha AMR i-codec / uthelekiso lwe-bitrate oluhambelana nomcebo. Isiphelo esingalahliweyo (AMR = WAV / FLAC / ALAC) sigcina yonke isampuli; isiphelo esilahliweyo (AMR = MP3 / AAC / OGG) simiselwe kwi-192 kbps ebonisa ngaphaya kweendlebe ezininzi.

I-AMR ifayili isebenzisa i-bitrate enjani?

Okwendalo 192 kbps ye-lossy AMR; idlula-kwi-lossless AMR. Nciphisa kwi-320 kbps ye-audiophile okanye kwi-96 kbps yelizwi/podcast. Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa kwi-bitrates ephantsi kakhulu.

Ingaba ukutshintsha ukusuka ku MP3 ukuya ku AMR kuya kunyusa ubunjani besandi sam?

Ukuba MP3 ilahlekile kwaye AMR ayilahleki (umzekelo MP3 → WAV), ifayili AMR ayingcono kune MP3 — awunakubuyisela ulwazi olusele luthunyelwe. Ukuba MP3 ayilahleki kwaye AMR ilahlekile, lindele ukuba i-AMR codec iphinde icinezele; kwi-192 kbps oku kucacile kuninzi lwezinto eziquletheyo.

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, imifanekiso ye-albham ifundwa kwi MP3 kwaye ibhalwe kwi AMR isiqulathi seefayili (lapho i-AMR ixhasa i-tags, eyenza zonke eziqhelekileyo).

Ndingaguqula izigidi zeefayili MP3 zibe AMR?

Ewe - susa isiqulathi seefayili se MP3 ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba iphele kwimizuzu emininzi.

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

Ngokungagqibekanga ewe (48 kHz MP3 → 48 kHz AMR). Ukuba ufuna ukunyusa isampulu ukuhambelana (umzekelo. 96 kHz → 44.1 kHz yokushicilela i-CD) ukhetho lwesampulu-yexabiso eliphambili yenza oku ngesampulu ephezulu yomgangatho.

Ndingazilungisa njani ilizwi kwinyathelo MP3 ukuya kwi AMR?

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

Ingaba i-AMR iya kudlala kwi-stereo yemoto yam / i-iPod / i-Sonos?

I-MP3 idlala kwihlabathi liphela. I-AAC idlala kwi-Apple, i-Android, i-Sonos. I-FLAC idlala kwi-Sonos ne-Android, incinci kakhulu kwi-iPods edala. I-WAV idlala kuyo yonke into kodwa ikhulu. Iinketho eziphambili ziquka isixhobo esimiselweyo kwezi zinjongo eziqhelekileyo.

Ingaba ifayili yam MP3 ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu MP3 ziqhubekekiswa kubasebenzi abamiselweyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise okuqulethwe sisiqulatho sesandi.

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

I-codec efanayo ye-re-mux: 10-30 imizuzwana. Yenza kwakhona ikhowudi kwi-codec eyahlukileyo: ngokuqhelekileyo 10-20% yobude bomthombo, ngoko ke i-1-iyure MP3 → AMR igqiba kwimizuzu eyi-6-12.

Kutheni i-AMR ifayili inamandla / ipholile kune-MP3 imvelaphi?

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba uvule ukhetho lokumisela ngokuqhelekileyo. Ukuba ubona utshintsho lomphakamo, umdlali wakho wesandi okanye ilayibrari yemidiya inokuba isebenzisa ukuphinda udlala ukufumana kwakhona okanye ukulungisa i-track nganye kukudlala — hayi nathi.

Ndingaguqula i MP3 i-streaming downloads kwi AMR?

Ukuba i-MP3 ilayishwe ezantsi ingakhuselwanga (akukho DRM), ewe. Iifayili ezisasazwayo ezifihliweyo nge-DRM (i-Spotify, i-Apple Music) zifihliweyo kwinqanaba le-bit kwaye asikwazi ukuziqhubekekisa. Amacebo e-Bandcamp, ukulayisha i-SoundCloud, kunye nokulinganisa kobuqu buguqulwa kakuhle.

MP3

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