Indlela yokuguqula MPEG ukuba MP3

Inyathelo 1: Layisha eyakho MPEG iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho MP3 iifayile

MPEG ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwifayili yam MPEG njenge MP3?

Layisha phezulu ifayili MPEG kwaye umguquli ukhupha umsinga wesandi, emva koko uguqula ikhowudi ibe yi MP3. Akukho sibini sevidiyo esidlulayo - irekhodi elibonakalayo lilahliwe ngokuzenzekelayo ngoko ke ukutywina kukhawuleza kakhulu kune-encoding epheleleyo.

I-MP3 ekhutshiweyo isebenzisa i-bitrate yesandi ethini?

I-bitrate emiselweyo ye-lossy MP3 yi-192 kbps, ebonisa ngaphaya kwengoma. Ungayicima i-320 kbps (audiophile) okanye i-96-128 kbps (ilizwi / ipodcast / ifayili encinci). I-bitrate esuka ezantsi ivela kwiinketho eziphambili phambi kokuba ucofe uguqule.

Ingaba ndiya kulahlekelwa umgangatho wesandi xa ndisuka kwi-MPEG ukuya kwi-MP3?

Ukuba MP3 ayilahleki (WAV, FLAC), isampuli nganye igcinwa ngokuchanekileyo. Ukuba MP3 ilahlekile (MP3, AAC, OGG, Opus), i-MP3 codec iphinda icinezele umbhalo wesandi - kwi-192 kbps isiphumo sicacile kuzo zonke iziqulatho. Ukuya kwi-lossy → ayilahleki akuzukubuyisela iinkcukacha ezisele zilahlekile.

Ingaba i-MP3 yesandi igcina i-sample rate yangaphambili?

Ngokungagqibekanga ewe — 48 kHz yesandi kwi MPEG yakho ihlala i-48 kHz kwi-MP3 yemveliso. Ukukhupha i-CD okanye ukulungelelanisa umdlali okhoyo ungakhupha i-sample ukuya kwi-44.1 kHz nge-sample-rate dropdown; i-resampler ikwi-SoX-grade esezingeni eliphezulu.

Ndingayikhupha i-audio kwiifayili ezininzi MPEG kwi MP3 kwiqela elinye?

Ewe — susa isiqulathi seefayili ze MPEG kwaye sikhuphe isandi ngokuthe tye. Abasebenzisi abaphezulu bafumana abasebenzi abathe tye abaninzi; kwifayili ye-50-batch le yinto eyahlukileyo phakathi kwemizuzu emibini kunye nemizuzu emihlanu.

Ingaba i-MP3 iya kuphawulwa ngesihloko / umculi / i-metadata ye-albham?

Ukuba i MPEG ithatha isahluko okanye i-metadata yokuhamba, siyakopa isihloko / umculi / imihlaba ye-albham kwi MP3 isiqulathi seefayili. Ukuba akunjalo, i MP3 iza ngaphandle ingaphawulwanga — sebenzisa umhleli we-tag (Mp3tag, Picard) emva korhwebo ngaphandle lokufaka i-tag eninzi.

Ithatha ixesha elingakanani ukutsala i-MP3 yesandi ukusuka kwi-MPEG yeyure?

I-audio demux + encode ikhawuleza - iqhelekileyo 5 ukuya kwi 15% yobude bomthombo. I-1-iyure MPEG → MP3 igqiba kwimizuzu emithathu ukuya kwi 9 kwindlela eqhelekileyo yokuhambisa; i-Premium parallelism icima oku ngaphezulu kwimisebenzi yeqela.

Ndingayikhupha icala le-MPEG yesandi njenge-MP3?

Akukho kule sixhobo ngokuthe ngqo — khupha isandi esipheleleyo njenge MP3, emva koko sebenzisa /audio-trim/ okanye /audio-cutter/ ukucima icandelo. Umendo wenyathelo elinye uhlala ukhawuleza kunenkqubo edityanisweyo kwaye ukunika ulawulo oluchanekileyo lwenqanaba le-waveform.

Ingaba ifayili yam MPEG ifihlakeleyo ngexesha lokukhupha isandi?

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngasinye: abasebenzi ababekwe ngokuzimeleyo, akukho hlaziyo lomuntu, ukucinywa okuzenzekelayo ngaphakathi kwemizuzu yokugqitywa. Ifestile yokugcina epheleleyo ikwi /privacy/.

Kutheni le nto ifayili MP3 ineengcambu ezingasebenziyo apho i MPEG ikwisandi?

I-MPEG iqulethe iingoma ezininzi zesandi kwaye i-demuxer ithathe i-stream engenanto okanye encedisayo. Sebenzisa isikhethi esiphambili "i-stream yesandi" ukukhetha i-stream 0, 1, 2 ngokucacileyo, okanye ubeke i-MP3 kwisiqulathi seefayili esixhasa i-multi-track output (FLAC, OGG).

Ndingagcina i-MP3 njenge-stereo, mono, okanye i-5.1 surround?

Ubeko lwesiqhagamshelanisi lugcinwa ukusuka kwi MPEG ngokumiselweyo - i-5.1 MPEG ivelisa i-5.1 MP3 ukuba i-MP3 codec ixhasa loo nto (AAC, FLAC, OGG, Opus). Ukhetho lokudibanisa ezantsi lukhuthaza i-stereo okanye i-mono - luncedo kwipodcast yokuhamba komsebenzi apho iingoma ezijikelezayo zilahleka kwi-bitrate.

Ingaba i-MP3 ekhutshiweyo iya kudlala kwi-iPhone, kwi-stereo yemoto, kunye ne-Sonos?

I-MP3 idlala naphi na ngaphandle komngcipheko wokuhambelana. I-AAC idlala kwi-Apple, i-Android, kunye ne-Sonos. I-OGG / Opus ifuna umdlali omtsha kwi-iOS. Isixhobo esiphambili esimiselweyo esithe tyaba sikhetha i-MP3 codec enokuthi idlala kwi-hardware yakho emiselweyo.

MPEG

I-MPEG (iQela leeNgcali zeMifanekiso eshukumayo) lusapho lwevidiyo kunye neefomati zokucinezela iaudio ezisetyenziswa ngokubanzi ukugcinwa kwevidiyo kunye nokudlala kwakhona.

MP3

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