WAV kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyiguqula kanjani i-WAV yomsindo ibe yi-AMR ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele WAV futhi umguquli ukhetha i AMR codec ne-bitrate ukufana nomsuka. Ukungabi nalutho AMR (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho AMR (MP3 / AAC / OGG / Opus) iphutha ku-192 kbps ecacile kulezi zindlebe eziningi. WAV igcina ngokuvamile i-PCM engacindezelwanga engaqondakali — yonke isampula igcinwa ngokugcwele, noma yikuphi ububanzi be-bit nesampula yezinga elithathwe. I-AMR iyi-narrowband speech codec esebenza phakathi kuka-4.75 no-12.2 kbps, emodela i-human vocal tract ngaphezu kwe-audio spectrum ephelele.

Ingabe ngilahlekelwa yikhwalithi eningi uma ngiguqula WAV kuya ku AMR?

Ezinye, futhi zihlala - lokhu kuyindlela eyodwa lapho ulwazi luthunyelwe khona. WAV ligcina yonke imibiko ngokugcwele; AMR lisusa lokho imodeli ye-psychoacoustic icabanga ukuthi awukwazi ukulalela. Ku-192 kbps futhi ngaphezu kwalokho, i-prediction iyilungile ngokwanele ukubukeka kahle kuningi kwamathuluzi nemishini. Gcina i-WAV njenge-master yakho, ngoba awukwazi ukubuyela kuyo kusuka ku-AMR.

Yini ekwenzeke kumsindo othile uma uguqula WAV ku AMR?

Ihlolwe phansi ku-stereo, ngoba AMR ayinayo indlela esebenzayo ye-multichannel. Ukuxuba okuphansi kusetshenziswa izilinganiso ezijwayelekile ukuze umhlangano we-channel ephakathi uhlale ucacile futhi izingqimba zixhunywe ku-level ephansi. Noma yini esekelwe ku-channel ehlukile ihamba lapho lokhu kwenziwa. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Kungani umculo uzwakala ubuhlungu kulo mguquko?

Ngenxa yokuthi ingxenye eyodwa iyi-codec yokuxoxa hhayi i-codec yomculo. Imodelisa i-human vocal tract futhi isusa konke okungaphandle kwe-bandwidth yefoni, okulungile ku-voice memo futhi kulahlekile kunoma yini enezithuluzi ngaphakathi. Ukushintshana eduze kwayo akukwazi ukubuyisela izifremu ezilahlekile — azikhombisile endaweni yokuqala. WAV ikhulu kakhulu — cishe i-10 MB ngemingwane ye-stereo ngekhwalithi ye-CD — futhi ifomu elidala line-4 GB ye-loft futhi akukho indawo ye-tags efanele.

Ingabe ukurekhoda okude WAV kuzokhuphula ngokuphumelelayo?

Ama-akhawunti amahhala afinyelela ku-100 MB ngefayela ngalinye, futhi WAV ahamba ku-10 MB ngomzuzu ngayinye kwi-stereo ngoba akukho okucindezelwe kulo - yonke isampula igcinwa ngokubanzi okugcwele. Imizuzwana eyisithupha ikhona eqenjini. I-Premium iphakamisa umkhawulo ngokuqinile, futhi ifomu line-4 GB ye-cage yayo ngaphesheya, ngakho-ke izingqungquthela ezide zifika zihlukaniswe zibe yizingxenye ezilinganiselwe; zulazisa ngazo ndawonye futhi zithathwa njengemisebenzi eyodwa.

Yini i-bitrate ezoba yihele elitholakele AMR lisebenzisa?

Iphutha lingu-192 kbps ku-lossy AMR; dlula-nge-lossless AMR. Yisuse ku-320 kbps ku-audiophile noma ku-96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku-audible fidelity; ngaphansi kwe-96 kbps i-lossy artifacts ibonakale kumculo.

Ingabe ukudlula kusuka ku WAV kuya ku AMR kuzonciphisa ukhwalithi yomsindo wami?

Uma WAV ilahlekelwa yinto futhi AMR ayilahlekelwanga (isibonelo MP3 → WAV), AMR ayingcono kuna WAV — awukwazi ukubuyisela imininingwane elahlekile. Uma WAV ilahlekelwa yinto futhi AMR ayilahlekelwanga, AMR i-codec icindezela kabusha; ku-192 kbps imiphumela icacile kuningi kwezithameli.

Ingabe i-WAV kuya ku-AMR iguqula igcina ID3 / metadata tags?

Yebo — isisihloko, umculi, i-album, unyaka, inani le-track, kanye ne-album art zifundwa kusuka ku WAV ibhokisi futhi zibhalwe ku AMR ibhokisi lapho ifomu lixhasa iziphawuli. Zonke izinhloso ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha iziphawuli kahle; i-WAV emnyama ayisebenzi. I-AMR iyi-Adaptive Multi-Rate, i-codec yokukhuluma i-3GPP ejwayelekile yezingcingo zokukhuluma ze-GSM nezinhlelo zokurekhoda amagama ezimoto.

Ingabe ngingakwazi ukushintsha amahele amakhulu WAV ku AMR?

Yebo - khipha isibaya se WAV amafayela ngaphakathi futhi sizoziphatha ngokuhambisana. I-Premium inemisebenzi eminingi ehambisanayo futhi akukho lutho oluphezulu lwesayizi yefayela ngalinye, ngakho-ke i-500-file batch iqedela imizuzu endaweni yamahora angama-10.

Ingabe i-AMR izogcina isilinganiso esifanayo sesampula njenge-WAV?

Ngokungajwayelekile yebo — 48 kHz WAV ihlala 48 kHz ku AMR. Uma ufuna ukusatshalaliswa ngezansi ukuze kusebenze (96 kHz → 44.1 kHz ukuthwebula i-CD), isampula-rate option ifaka ukusatshalaliswa okusezingeni eliphezulu kulowo mkhawulo wokucofoza.

Ingabe ngikwazi ukushintsha umsindo uma ngiguqula WAV kuya ku AMR?

Yebo — i-loudness-normalize option ifaka i-ITU-R BS.1770 / EBU R128 normalization ku-AMR, idinga -14 LUFS (isilinganiso sokusakaza) noma -16 LUFS (isilinganiso sepodcast). Kuhle uma uhlela ama-tracks amastered kuma-levels ahlukene.

Ingabe AMR yami izodlala ku-car stereo, iPod, ne-Sonos?

MP3 idlala kuwo wonke amathuluzi. AAC idlala ku-Apple, ku-Android, ne-Sonos. FLAC idlala ku-Sonos ne-Android kodwa hhayi ku-iPods ezidala. WAV idlala kuwo wonke amathuluzi kodwa ikhulu. Idivayisi ethuthukisiwe-isethelwe ngaphambili ikhetha i-AMR codec elungele i-hardware yakho efanele. I-AMR yenza ukurekhodwa kwezwi kube ncane kakhulu - ihora lokuxoxa lifaka ama-megabytes ambalwa - futhi yilokho okunye amafoni amaningi aqhubeka nokurekhoda ukufona.
