AMR waa codsi codka narrowband socda u dhexeeya 4.75 iyo 12.2 kbps, qaabeynta wadnaha codka aadanaha ka badan sida ay u kala duwanaansho audio buuxa.

Maxaa ka dhacaa codka multichannel marka la beddelo AC3 ilaa AMR?

Wax kasta oo ku xiran meelaynta kanalka kala duwan ayaa la tagay markaa.

Maxaa ka dhigaya music maqalka sida xun ee isbedelkaas?

Waayo, dhinac ka mid ah waa codsi codsi hadalka ka badan codsi codsi muusig.

AC-3 waa aan wax ku ool ah oo ay heerarka casriga ah oo aan la aqbali karin by browsers, telefoonada ama ciyaartoyda web badan oo aan la downmix in stereo.

Fadlan faahfaahinta faahfaahinta faahfaahinta AMR

Default waa 192 kbps loo baahan yahay AMR; pass-through loo baahan yahay AMR. Ku dar 320 kbps audiophile ama 64-96 kbps loogu talagalay buugaagta maqalka ah ee hadalka (caddeysan codka, qaybinta faahfaahinta faahfaahinta).

Ma ka yarayn kartaa tayada maqalka haddii aan ka tago AC3 ilaa AMR?

Haddii AC3 ay tahay mid khasaartay iyo AMR ay tahay mid aan khasaarin (tusaale ahaan MP3 → WAV), faylka AMR ma aha mid ka fiican AC3 — ma awoodi kartid inaad soo ceshato macluumaadka horeyba loo tuuray. Haddii AC3 ay tahay mid khasaartay iyo AMR ay tahay mid khasaartay, ka yaab AMR codec si ay u soo celiso; 192 kbps waxaas oo dhan waa mid cad oo loogu talagalay waxyaabaha badankood.

AMR ma ku hayn doontaa tirada tusaale ee AC3?

By default haa (48 kHz AC3 → 48 kHz AMR). Haddii aad u baahan tahay in ay hoos u soo bandhigaan si ay u wada shaqeeyaan (tusaale ahaan 96 kHz → 44.1 kHz si ay u CD burning) ka horumarsan tusaale-ka-raac ikhtiyaarka sameeyaan this la tayo sare ah resampling.

Ma ku hagaajin karaa codka AC3 ilaa AMR?
