Guqula WAV kuya MP3

Ezinye, futhi zihlala - lokhu kuyindlela eyodwa lapho ulwazi luthunyelwe khona. WAV ligcina yonke imibiko ngokugcwele; MP3 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-MP3. WAV igcina ngokuvamile i-PCM engacindezelwanga engaqondakali — yonke isampula igcinwa ngokugcwele, noma yikuphi ububanzi be-bit nesampula yezinga elithathwe. MP3 ilahlekelwa: imodeli ye psychoacoustic isusa iziqongo ezingezona ezivamile, ezivame ukuba ngu-128 kuya ku-320 kbps.

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe WAV, engeke ikwazi ukugcinwa kuphi naphi. MP3 ifaka isihloko, umculi, i-album, unyaka, inani le-track kanye ne-cover art efakwe ngaphakathi kwebhokisi, ngakho-ke i-library yomculo ifaka ngokulungile ngaphandle kokungena ngesandla. Akukho lutho olushaya i-MP3 ngokuhambisana - i-car stereos, imishini ye-gym, i-DAPs ne-hardware eneminyaka engu-20 yonke ifunde ngaphandle kwemibuzo.

Ihlolwe phansi ku-stereo, ngoba MP3 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-MP3 ihlukaniswe ngokukhethekile yi-AAC ne-Opus nganoma yisiphi isivinini se-bit, ingagcina ngaphezulu kwama-channels amabili ngokunembile, futhi ihlala ifaka ukulibazisa okuncane kwe-encoder.

Ama-akhawunti amahhala afinyelela ku-100 MB ngefayela ngalinye, futhi WAV ama-akhowudi asebenza kabanzi ngoba ifomu lifaka i-chunk ngayinye engaphezulu kwedatha yevidiyo. I-Premium iphakamisa i-cap ngokuqinile. Uma ihele lihlukaniswe ngama-parts amanani ngenxa ye-format ceiling, thumela ngazo zonke futhi zithathwe njengemisebenzi eyodwa. 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.

Iphutha ngu-192 kbps ku MP3 olahlekelwayo; udlulisa-nge- MP3 ongenalutho. Nciphisa ku-320 kbps ku-audiophile noma ku-64-96 kbps ku-audiobooks ekhuluma-magama (icacile ku-voice, ihlukanise ubukhulu befayela ngamaphesenti).

Uma WAV ilahlekelwa futhi MP3 ayilahleki (isibonelo MP3 → WAV), ihele MP3 alingcono kuna WAV — awukwazi ukubuyisela imininingwane esele ilahlekile. Uma WAV ilahlekelwa futhi MP3 ayilahleki, cabanga ukuthi i-MP3 codec izocindezela futhi; ku-192 kbps lokhu kucacile kunoma iyiphi ingxenye.

Yebo — isihloko, umculi, i-album, unyaka, inani le-track, i-album art, nama-chapter markers (abalulekile kuma-audiobooks) afundwa kusuka ku-WAV futhi abhalwe ku-MP3 ibhokisi lapho i-MP3 ifomu lixhasa amathegi. Ukwakhiwa kwe-audiobook M4B kuhamba-hamba ku-M4B ne-AAX → M4B output.

Yebo — susa isibaya se WAV amafayela ngaphakathi futhi sizoziphatha ngokufanayo. I-Premium inemisebenzi eminingi efana ne-parallel futhi akukho lutho oluphezulu lwesayizi yefayela ngalinye, ngakho-ke i-500-file batch iphele ngemizuzu endaweni yamahora angama-10.

Ngokuzenzakalela yebo (48 kHz WAV → 48 kHz MP3). Uma ufuna uku-downsample ukuhambisana (isibonelo 96 kHz → 44.1 kHz yokushaya i-CD) isinqumo esiphezulu sesampula-rate sikwenza lokhu ngekhwalithi ephezulu yoku-resamply.

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku MP3 kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela), -16 LUFS (isizinda sepodcast), noma -23 LUFS (isizinda sencwadi yezwi). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.

MP3 idlala emhlabeni wonke. AAC idlala ku Apple, ngaphezu Android, Sonos. FLAC idlala ku Sonos ne Android, ngaphezu kahle ku iPods edlule. M4B audiobooks dlala ngesigaba ukuzulazula ku iOS Books, Audiobookshelf, kanye Smart Audiobook Player. Izinto ezikhethwayo ezisezingeni eliphezulu zifaka idivayisi imise.
