Londoloza njengokuthi MP3 lapho ifayela kufanele livuleke noma kuphi, WAV lapho liyofakwa kuhleli, kanye WebM noma OGG lapho ufuna ifayela elincane ngosayizi kodwa ngekhwalithi yezwi elihle. Ku-Audio Recorder – Voice Recorder zonke ezine zivela ekuthathweni okufanayo, ngakho ungakhipha ukurekhoda okukodwa ngefomethi eziningi ngaphandle kokukurekhoda kabusha.
Ukukhetha kwefomethi kuse ngaphansi kwe-Izilungiselelo → Londoloza njengokuthi. WebM iyimfanelo yokungaguquki. Lesi silungiselelo sithinta kuphela ifayela olitholayo uma ucindezela Layisha noma Yabelana; ikhophi ngaphakathi kwekuthebhu evulekile ihlala iyifana noma yini oyikhethayo.
Yini ifomethi ngayinye empeleni
Abantu bavame ukuphatha lezi njengama-"khwalithi" amane. Empeleni zingama-codec amabili emathinini amathathu, kanye nenketho eyodwa engacindezelwanga.
| Londoloza njengokuthi | Ikhodi ngaphakathi | Ukucindezelwa | Ukusheshiswa komsebenzi kuhlangene nekhwalithi? | Ukusetshenziswa okuvamile |
|---|---|---|---|---|
| WebM | Opus | Ilahleko | Yebo | Ukudlalwa kwabha, ukulayishwa kuwebhu, amafayela amancane kakhulu |
| OGG | Opus | Ilahleko | Yebo | Umsindo ofanayo njenge WebM ku-container abanye abadlali abayithanda |
| MP3 | MP3 (LAME encoder, ehlanganisiwe) | Ilahleko | Yebo | Izimoto ezindala zesitudiyo, isoftware yasehhovisi, noma ubani ocele "i MP3" |
| WAV | 16-bit PCM | Akukho | Cha | Abahleli bomsindo kwideskithophu, amathuluzi wokubhala phansi, ukugcinwa kwezinguqulo zomphathi ohleliwe |
WebM ne OGG ziphethe umsindo ofanayo we-Opus; okuhluke kuphela i-wrapper. Uma umdlali enqaba owodwa, zama omunye ngaphambi kokucabanga ukuthi irekhodi lophuliwe.
Indlela ukudluliswa kusebenza ngemuva kwebhathini
Ngenkathi uqopha, i-extension ibhala umsindo we-Opus ku-container ye-WebM esithwalweni sesiphequluli sendawo, isiqephu sonke sesekhondi eyodwa ngesikhathi. Leyo thatha egciniweyo iyisisekelo se-eksipothi ngayinye:
- WebM, engakhethwanga — amaphakethe e-Opus wokuqala aphindwa afakwe ebhodini ngokwesikhathi esifanele ukuze abadlali bakwazi ukufuna. Akukho ukufaka kabusha, ngakho akukho okulahlekile.
- WAV — ukuthathwa kudecodiwe ku-16-bit PCM ku-48 kHz futhi kubhalwe njengoba kunjalo. Kuyaqhubeka kungalahleki kusukela manje, kodwa akwazeki ukufaka imininingwane engakhona ukuqoshwa kwe-Opus ekuqaleni.
- OGG, WebM esikhethiwe — kudecodiwe futhi kufakwe kabusha ku-Opus ngamanani wekhwalithi yamanje.
- MP3 — kudecodiwe futhi kufakwe kabusha usebenzisa i-encoder ye-LAME ehlanganisiwe ngamanani wekhwalithi yamanje.
Le ndaba yokugcina ibalulekile: ukuthumela MP3 kuyisikhathi sesibili sokulahlekelwa ikhwalithi. Ezingeni eliphezulu noma elihle kakhulu kungenzeka ungakuzwa ekukhulumeni, kodwa uma izwi lizohlelwa, licindezelwe futhi ngelishwa levidiyo, bese lidlalwa ocingweni, zonke izinyathelo zokulahlekelwa ziyahlanganiswa. Ngaleso simo, thumela WAV kanye kuphela bese uvumela ithuluzi lokugcina ukuba lenze ukuphrinta okukodwa kuphela.
Ukukhetha ngokuya ngendawo oya kuyo
Ukuthumela kumuntu
MP3. Luhlobo olungenzeka kancane ukukhiqiza impendulo ethi "ngeke uvule le fayela". Inothi lezwi lamaminithi ayishumi ku-High cishe lingu-9.6 MB (128 kbps ÷ 8 = 16 kB ngomzuzwana × 600 s), lincane ngokwanele kuzo zonke izinhlelo zokusebenza ze-imeyili nezokuxoxa.
Ukuhlela kwisoftware yomsindo yekhompuyutha
WAV. Abahleli basibamba ngokuphelele i-PCM ngaphandle kwesinyathelo sokudecoda, futhi ugwema ukufaka MP3 encode ngaphansi kwanoma iyiphi indlela yokuthekelisa umhleli enza kamuva. Lindela amafayela amakhulu: 48 kHz, 16-bit mono WAV iyizinga elingu-96 kB ngomzuzwana, cishe 346 MB ngehora. Umhlahlandlela wosayizi wefayela unetafula eligcwele.
Ukulayisha kuwebhusayithi noma ukugcina i-archive
WebM. Kuyimisindo yokuqala engenalo ikhodi eyengeziwe, idlalwa ku-Chrome nakwezinye iziphequluli zesimanje, futhi kusethingi ye-High ezinzile ihora cishe lingu-58 MB. Umkhuba wami: gcina WebM njengokukopishwa kwe-archive futhi wenze MP3 kuphela uma othile ecela ezimbalwa.
Umdlali owamukela kuphela .ogg
OGG. Abanye abadlali bemidiya, izinjini zegeyimu, namathuluzi e-Linux alindele i-Opus esitsheni se-Ogg. Ikhwalithi yomsindo ifana ne-WebM esimisweni Sekhwalithi esifanayo.
Ikhwalithi ne-bitrate zisebenzisana nefomethi
Isilungiselelo Sekhwalithi (Okuvamile 64 kbps, High 128 kbps, Best 192 kbps) sisetshenziswa kabili: uma ukuthatha kurekhodiwe, futhi nalapho uthumela MP3, OGG, noma kusikiwe WebM. Ukuthunyelwa kusebenzisa noma iyiphi Ikhwalithi ekhethiwe ngesikhathi ucindezela u-Layisha.
Ngakho-ke ukuthumela ukuthatha Okujwayelekile njengokuthi MP3 Ngokukhethwa Okungcono Kakhulu kukunika ifayela elikhulu, hhayi elingcono. Okurekhodiwe kuphela okuke kwaba nemininingwane enenani elingu-64 kbps. Uma udinga Okuhle kakhulu, yikhethe ngaphambi kokuthi ucindezele okuthi Rekhoda. isichazi se-bitrate siya kulokho ileveli ngayinye ezwakalayo enkulumeni.
Imikhawulo eqotho
- OGG nokuthunyelwa kwe-WebM okusikiwe kusebenzisa isishumeki somsindo esakhelwe ngaphakathi se-Chrome. Uma isiphequluli sakho singakwazi ukukunikeza, i-popup ithi "Isiphequluli sakho asikwazi ukudala le fomethi. Zama WAV noma WebM."
- WebM kanye ne-OGG azivuli kuwo wonke amadivayisi. Amanye amadivayisi amadala kanye nabadlali abathile abakwezinye izinhlelo zokusebenza bayaziyeka. MP3 noma WAV kuyindlela ephephile yokusebenzisa.
- Ukuthumela okude kwe-WAV kanye ne-MP3 kuthatha isikhashana, ngoba konke ukuthatha kuqala kuyachazwa. I-WAV yehora elilodwa iphinde idinge izigidi eziningi zamabhayithi zendawo evulekile kufolda yakho ye-Downloads.
- Iziteshi ziqhubeka kuwo wonke amafomethi. Ukuthatha kwe-Mono kuthunyelwa njenge-mono WAV noma MP3; bheka mono noma stereo lomlomo lapho i-Stereo iyafaneleka khona.
Uma ukhumbula umthetho owodwa kuphela: rekhoda ngekhwalithi ofuna ngempela, gcina WebM njengomphathi, bese uthumela ezinye izinhlelo ngokwesidingo. Lapho uthathe okokuqala, ukuthumela kuqukethe ingxenye egcinwe kuphela — umhlahlandlela wokusika ukhombisa izibambo.
