Ingabe i-AMR izogcina isilinganiso esifanayo sesampula njenge-Opus?

Ngokuzenzakalela yebo (48 kHz Opus -> 48 kHz AMR). Uma ufuna ukusatshalaliswa okuphansi kokuhambisana (isibonelo 96 kHz -> 44.1 kHz yokushaya i-CD) isinqumo esiphezulu sesampula-rate siphatha lokhu ngesampula esezingeni eliphakeme le-polyphase.

Ingabe ngizolungisa umsindo ku-Opus kuya ku-AMR?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku AMR kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.

Ingabe i-AMR izodlala ku-stereo yemoto yami / iPod / Sonos?

MP3 idlala jikelele. AAC idlala ku Apple, Android abaningi, kanye Sonos. FLAC idlala ku Sonos kanye Android yamanje, ngaphezu kahle ku iPods edlule. WAV idlala konke kodwa kukhulu. Izinketho eziphezulu zifaka idivayisi presets lezi izinhloso ezivamile.

Kungani ihele AMR likhulu / lihlanzekile kunalelo Opus?

Akukho shintsho lokufinyelela oluzenzakalelayo kwenziwa ngaphandle kokuthi uvule isinqumo sokujwayelekile. Uma ubona ushintsho lwezinga, umdlali wakho wesandi noma ithala lemithombo kungase kusebenzise ReplayGain noma ukuguqulwa kwe-track-by-track kudlala — hhayi nathi.
