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 isampuli nganye; isiphelo esilahliweyo (AMR = MP3 / AAC / OGG / Opus) simiselwe kwi-192 kbps ebonisa ngaphaya kweendlebe ezininzi.

I-AMR ifayili isebenzisa i-bitrate enjani?

Okumiselweyo 192 kbps ye AMR elahlekile; idlula-ngaphaya (akukho bitrate yokucofa) ye AMR engalahleki. Nciphisa kwi 320 kbps yemveliso yeaudiophile, okanye 96 kbps yelizwi/podcast apho iifayile ezincinci zibalulekile ngakumbi kunenyani kwinqanaba eliphezulu.

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, i-AMR codec iphinda 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, kunye nemifanekiso ye-albham efakwe ngaphakathi ifundwa ukusuka kwi MP3 kwaye ibhalwe kwi AMR isiqulathi seefayili apho i-AMR ixhasa i-tags (ezizo zonke eziqhelekileyo).

Ndingaguqula izigidi zeefayili MP3 zibe AMR?

Ewe - susa isiqulathi seefayili se MP3 ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Pro 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 yohambelana (umzekelo. 96 kHz -> 44. 1 kHz yokushicilela i CD) ukhetho oluphambili lwesampulu- umyinge uphatha oku nge-polyphase resampler esezingeni eliphezulu.

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, kunye ne-Sonos. I-FLAC idlala kwi-Sonos kunye ne-Android ekutshanje, incinci kakhulu kwi-iPods edala. I-WAV idlala kuyo yonke into kodwa ikhulu. Iinketho eziphambili ziquka isixhobo esimiselweyo kwezi ntlawulo eziqhelekileyo.

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. Bona /privacy/ kwifestile yokugcina i-data.

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 engama-6-12 kwinkqubo eqhelekileyo yokuhambisa.

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 umkhondo ngamnye kukudlala — hayi nathi.

Ndingaguqula i-MP3 i-downloads ibe yi-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, i-SoundCloud, kunye nokulinganisa kobuntu buguqulwa kakuhle.

MP3

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