Sinthani M4A ku WAV

Sichoncho, ndipo ndibwino kuti mukhale wopanda kanthu: palibe chomwe chingachitike. M4A yomwe yatulutsidwa kale nthawi yoyamba yolemba, ndikuyika zomwe zilibe kanthu WAV zimasunga zomwezo - sizowonjezera. Fayilo imakula nthawi zambiri ndipo imawoneka ngati yofanana. Ndibe njira yoyenera yosinthira, chifukwa WAV siyiwonjezera chitukuko chachiwiri cha artefacts pamene mukutumiza. WAV ndi bwino mtundu kwa kusintha, mastering ndi archiving, chifukwa chakuti angathe re-encoded nthawi iliyonse popanda kusonkhana artefacts. M4A amachititsa zinthu ziwiri kwambiri zosiyana m'mbuyo kwa m'modzi kuwonjezeka - lossy AAC ndi lossless ALAC - ndi non-Apple hardware thandizo ndi zosagwirizana.

Siyimagwira ntchito. M4A imathamanga ndi metadata block yoyenera, koma WAV siyimagwira ntchito yoyenera ya woimba, album, track number kapena cover art, kotero ma tag amatulutsidwa osati kuwonongedwa.

DRM. Mtundu wa M4A mafayilo amasinthidwa ndi sitolo kapena pulogalamu yomwe idatulutsa, ndipo mawu osakira satha kusinthidwa ndi aliyense wosintha. Chomwecho chomwe mwachotsa nokha, cholemba, kapena chogula popanda kuteteza chimasinthidwa moyenera; kugula kwa licensed sichidzachitika.

Ngati M4A ndi lossy ndipo WAV ndi lossless (mwachitsanzo MP3 → WAV), fayilo ya WAV si yabwino kuposa M4A - simungathe kubwezeretsa zambiri zomwe zatulutsidwa. Ngati M4A ndi lossless ndipo WAV ndi lossy, yembekezerani kuti codec ya WAV ibwezeretse; pa 192 kbps izi ndi zosawoneka bwino kwa zinthu zambiri.

Mavidiyo ambiri m'modzi ntchito ayenera kulipira ndondomeko. Free kugwiritsa ntchito ndi imodzi wapamwamba pa kusintha, imodzi kusintha pa ola. Pa ndondomeko yolipira mukhoza kuwonjezera angapo owona kuti ntchito imodzi, ndiye download zotsatira zonse pamodzi kapena onse awo mu ZIP imodzi.

Mwachidule ndi yemweyo (48 kHz M4A → 48 kHz WAV). Ngati mukufuna kuchepetsa kusamvana kwa kugwirizana (mwachitsanzo 96 kHz → 44.1 kHz kwa kulemba CD) kusankha kwa kusamvana kwamphamvu kumachita izi ndi kusamvana kwabwino.

Sichingakhale m'njira imeneyi. Wosintha alibe kukhazikitsa loudness ndi kuchoka pa gawo monga momwe zilili. Kuti atenge mbali ya volume, kuyendetsa WAV kumaliza mwa njira Normalize chida pa webusaitiyi.

MP3 amasewera pafupifupi kulikonse. AAC amasewera pa Apple zipangizo, ambiri Android foni ndi Sonos. FLAC amasewera pa Sonos ndi Android koma si pa zaka za m'ma iPods, ndi WAV amasewera pa pafupifupi chilichonse koma amachititsa mavidiyo akulu. Palibe chipangizo presets pa nkhaniyi, choncho kusankha chitukuko format wanu wosewera mpira amathandiza.

Palibe munthu amamvetsera kapena kugawana audio, zomwe ndi zofunika kwa anthu audiobook mabuku, ndi uploaded M4A owona ndi awo anasinthidwa zidutswa zimasungidwa mwamsanga za 24 maola pambuyo kusintha.
