Ingabe i-MP3 izogcina isilinganiso esifanayo sesampula njenge-M4A?

Ngokuzenzakalela yebo (48 kHz M4A -> 48 kHz MP3). Uma ufuna ukusatshalaliswa ngezansi ukuze kusebenze (isibonelo 96 kHz -> 44.1 kHz ukubhala i-CD) isinqumo esiphezulu sesampula-rate siphatha lokhu ngesampula esezingeni eliphakeme le-polyphase.

Ingabe ngizolungisa umsindo ku M4A kuya ku MP3 isikhashana?

Yebo — i-loudness-normalize option ifaka i-ITU-R BS.1770 / EBU R128 normalization ku-MP3 output, ibeka i- -14 LUFS (isilinganiso sokusakaza) noma i- -16 LUFS (isilinganiso sepodcast). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.
