AMR → FLAC

Sichoncho, ndipo ndibwino kuti mukhale wopanda kanthu: palibe chomwe chingachitike. AMR yomwe yatulutsidwa kale nthawi yoyamba yolemba, ndikuyika zomwe zilibe kanthu FLAC zimasunga zomwezo - sizowonjezera. Fayilo imakula nthawi zambiri ndipo imawoneka ngati yofanana. Ndibe njira yoyenera yosinthira, chifukwa FLAC siyiwonjezera chitukuko chachiwiri cha artefacts pamene mukutumiza. FLAC amakupatsani WAV fidelity pa theka la kukula, ndi bwino metadata tags ndi embedded ntchito zojambulajambula, amene ndi chifukwa chake amayang'ana lossless nyimbo laibulale. AMR amawononga nyimbo: yake 8 kHz bandwidth amachotsa zonse pamwamba foni ma frequencies, ndi palibe ndalama ya re-encoding amabweretsa izo kumbuyo.

Yes, ndipo ndi cholinga chabwino kuposa AMR, amene ali ndi kulikonse otsimikiza kuti abwezeretse chilichonse cha izo. FLAC amachita mutu, woimba, album, chaka, track number ndi embedded cover art mu chomeracho, kotero nyimbo laibulale amapereka bwino popanda manual kupita.

Nthawi zambiri sichoncho. AMR imasinthidwa ndi chilichonse, kuphatikizapo magalimoto agalimoto ndi osewera okalamba; FLAC amafunikira mapulogalamu omwe amadziwa codec, omwe nthawi zambiri amakhala ndi zida zosagwirizana. Ngati malo osankhidwa ndi stereo yagalimoto kapena wosewera wonyamula, ndiye kuti ndi chitsimikizo cholimba chokhala pa AMR. FLAC ndibe nthawi zambiri kuposa bwino lossy wapamwamba, ndi Apple's ecosystem anawonjezera kugwirizana koyamba ndi mosasamala.

Chifukwa chimodzi mwazigawo zake ndi codec ya mawu kuposa codec ya nyimbo. Imakhala ndi maonekedwe a munthu woimba ndipo imachotsa chilichonse m’mbali mwa bandwidth ya foni, chomwe ndi choyenera kwa mawu olemba mawu komanso chowononga kwa chilichonse chomwe chili ndi zida. Kusintha kuchokera ku izo sikungabwezeretse ma frequencies osakhudzidwa — iwo sanali kusinthidwa pamalo oyamba.

Mtengo woyambirira ndi 192 kbps kwa lossy FLAC; pass-through kwa lossless FLAC. Chotsani 320 kbps kwa audiophile kapena 96 kbps kwa mawu / podcast. Chosankha chimasintha kukula kwa fayilo ndi kumvetsera; pansi pa 96 kbps lossy artifacts amawoneka pa nyimbo.

Ngati AMR ndi yowonongeka ndipo FLAC ndi yopanda kusowa (mwachitsanzo MP3 → WAV), FLAC si yabwino kuposa AMR - simungathe kubwezeretsa zambiri zomwe zatulutsidwa. Ngati AMR ndi yopanda kusowa ndipo FLAC ndi yopanda kusowa, FLAC codec imabwezeretsa; pa 192 kbps zotsatirazi ndizosawoneka bwino kwa zinthu zambiri.

Ndikoyenera - dzina, woimba, album, chaka, mndandanda wa nyimbo, ndi album art amawerengedwa kuchokera ku AMR kontena ndi kulemba ku FLAC kontena komwe mtundu umathandizira ma tag. Zonse zofunikira (MP3, AAC, FLAC, OGG) zimayendetsa ma tag bwino; WAV yosapanga dzimbiri siyichita. FLAC ndi Free Lossless Audio Codec, otsegulira mtundu kuchokera 2001 kuti compresses popanda kuchotsa imodzi chitsanzo.

Yai - chotsani fayilo ya AMR ndikuwapanga mofanana. Premium ili ndi ogwira ntchito ambiri mofanana ndi malire a fayilo, kotero fayilo ya 500-file batch imatha m'maola angapo osati m'maola angapo.

Mwa default yes — 48 kHz AMR imakhala 48 kHz mu FLAC. Ngati mukufuna kulowetsa kuti mugwirizane (96 kHz → 44.1 kHz kwa kulemba CD), kusankha kwa sampling-rate kumagwiritsa ntchito kulowetsanso kwabwino kwambiri panjira yofanana yolemba.

Ndiye — njira yosintha mawu imagwiritsa ntchito ITU-R BS.1770 / EBU R128 yosintha mawu ku FLAC, yolenga -14 LUFS (mtengo wosinthira) kapena -16 LUFS (mtengo wosinthira podcast).

MP3 imasewera kulikonse. AAC imasewera pa Apple, ambiri a Android, ndi Sonos. FLAC imasewera pa Sonos ndi Android koma si pa iPods oyambirira. WAV imasewera pa chilichonse koma ndi chachikulu. Kusintha kwa chipangizo chosinthika chimasankha codec ya FLAC yosinthidwa kwa zida zanu zofunikira.
