M4A ukuba OGG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4A yesandi ibe yi-OGG ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili M4A kwaye umguquli ukhetha i OGG codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko OGG (WAV / FLAC / ALAC) ugcina yonke isampuli nge-bit-identical; ukungabikho kolahleko OGG (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngokucacileyo kwiinwele ezininzi. I-M4A igcina i-AAC kwiziganeko ezininzi, okanye i-Apple Lossless (ALAC) xa ivela kwi-rip engalahlekiyo. I-Vorbis ngaphakathi kwe-OGG ilahlekile kwaye isebenzisa i-bitrate etshintshayo ngokumiselweyo, ngoko umgangatho umiselwe njengomgangatho kunokuba ubungakanani obuthe nkqo be-kbps.

Ingaba ukutshintsha M4A ukuya ku OGG kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i OGG 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 OGG ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

Kutheni ezinye zeefayili zam M4A azitshintshi?

DRM. Iqela elincinci le M4A iifayile zifihliweyo yindawo yokurhweba okanye isoftware ekhupheleyo, kwaye umsindo ofihliweyo awunakucinywa uphawu nganoma uphi umguquli. Nantoni na oyiyikhuphe ngokwakho, uyirekhode, okanye uyithengise ngaphandle kokhuselo iguqula ngokuqhelekileyo; ukuthengiswa kwelayisensi akuyi kwenza njalo. M4A ifihla izinto ezimbini ezihlukileyo eziphambili kwesinye isiqalo — lossy AAC kunye lossless ALAC — kwaye i-Apple engasebenziyo hardware inkxaso ayihambelani.

Ingaba i OGG iyadlala kwimoto yam okanye kwizixhobo ezidala?

Ihlala ingasebenzi. M4A ikhowudiwe yiyo yonke into, kubandakanya iyunithi yemoto yomlomo kunye nabadlali abadala; OGG ifuna isoftware eyaziyo i-codec, eyona hardware ihlala ingekho. Ukuba indawo efanelekileyo yimoto yestereo okanye umdlali ophathekayo, oku kukholelwa kakhulu ukuba uhlala kwi M4A. I-OGG inenkxaso ephantsi yezixhobo zekhompyutha — ii-stereo zemoto, ii-iPods ezidala kunye neeTV ezininzi azibonisi ifayile nanini na.

I-OGG ifayili ephumayo izakusebenzisa i-bitrate enjani?

Okumiselweyo yi 192 kbps ye-lossy OGG; igqityiwe-kwi-lossless OGG. Nciphisa kwi 320 kbps ye-audiophile okanye 96 kbps yelizwi/podcast. Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa; ngaphantsi kwe-96 kbps i-lossy artifacts ibonakala kwingoma.

Ingaba ukutshintsha ukusuka ku M4A ukuya ku OGG kuya kunyusa ubunjani besandi sam?

Ukuba M4A ilahlekile kwaye OGG ayilahleki (umzekelo MP3 → WAV), i OGG ayingcono kune M4A — awunakubuyisela ulwazi olusele lulahlekile. Ukuba M4A ayilahleki kwaye OGG ilahlekile, i OGG codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kumxholo omkhulu.

Ingaba i-M4A ukuya kwi-OGG igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi M4A isiqulathi seefayili kwaye ibhalwe kwi OGG isiqulathi seefayili apho ifomati ixhasa iithagi. Zonke iziseko eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha ii-tags kakuhle; i-WAV egqityiweyo ayisebenzi. OGG yiXiph.Org equlethe, ehlala igcina iVorbis yesandi, eyenziwe ngowe-2000 njengento efana ne-MP3 engekhoyo kwipateni.

Ndingaguqula izigidi zeefayili M4A zibe OGG?

Ewe - susa isiqulathi seefayili se M4A 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-OGG iya kugcina inqanaba lesampuli elifanayo njenge-M4A?

Ngokungagqibekanga ewe — 48 kHz M4A ihlala i-48 kHz kwi OGG. Ukuba ufuna ukunyusa isampuli ukuze ihambelane (96 kHz → 44.1 kHz yokushicilela i-CD), ukhetho lwesampuli-yexabiso lisebenzisa ukuphinda uthathe isampuli esezingeni eliphezulu kwindlela efanayo yokugqitha kwekhowudi.

Ndingazilungisa njani i-loudness xa ndiguqula i-M4A ibe yi-OGG?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwi OGG, ukubeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast). Isetyenziswa xa kudityaniswa iingoma ezilawulwa kumanqanaba ahlukeneyo.

Ingaba i-OGG yam iya kudlala kwi-stereo yemoto, i-iPod, kunye ne-Sonos?

I-MP3 idlala naphi na. I-AAC idlala kwi-Apple, i-Android, ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayiyiku-iPods ezidala. I-WAV idlala naphi na kodwa ikhulu. Isixhobo esiphambili esimiselweyo esithe nkqo sikhetha i-OGG codec elungelelaniswe kakuhle kwi-hardware yakho emiselweyo. I-OGG Vorbis ibetha i-MP3 kwi-bitrate elinganayo kwaye ihambisa akukho xabiso lelayisensi, nto leyo eyenza ukuba i-enjini yomdlalo kunye nesoftware evulekileyo ithathele ingqalelo i-elektroniki.

Ingaba ifayili yam M4A ifihlakeleyo ngexesha lokuguqulwa ukuya kwi OGG?

Ewe — iifayile ezilayishwe phezulu M4A ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sisebenzise imixholo yesandi. Ifestile yokugcina epheleleyo ikwi /privacy/.

M4A

I-M4A yifomati yefayile yomsindo esondeleleneyo neMP4. Ibonelela ngoxinzelelo oluphezulu lweaudio ngenkxaso yemetadata, iyenza ilungele usetyenziso olwahlukeneyo.
