Faster Whisper imalemba M4A pa 64-256 kbps AAC m'ma ~1% a WAV mwatsatanetsatane pamodzi ndi kujambula kwa mafoni. Kuyenera kudziwika kuti mfundo yoyenera ndi mtundu wa kujambula kwa mafoni (mikrofoni, malo, kuwala kwa wokamba nkhani), si M4A codec.

M4A mafayilo ndi 1-2 MB/min at 128 kbps AAC chifukwa chake ambiri a uploads amalandiridwa bwino pansi pa 500 MB yayikulu. Maakaunti aulere amatha kulemba mpaka maminitsi 5 pa kutsitsa. Maphunziro olipira amapita mpaka maola 2. Ngati mukukumana ndi malire a mafayilo akuluakulu, onani chida cha audiobook / longform chomwe chimagwira ntchito yolemba nthawi yambiri.

No. Our transcriber amasamalira M4A mogwirizana - kusintha kwa MP3 koyamba adzawonjezera re-encoding gawo (pofunika lossy) ndi kuwononga nthawi yanu. Mmodzi ku wyjątku ndi ngati M4A wapamwamba amagwiritsa ntchito codec osiyana wathu decoder sakudziwa (rary); tidzakuwuzani kuti pa kutsitsa ndi inu mukhoza kusintha kudzera wathu ufulu Audio Converter.
