Ngiyikhipha kanjani umsindo kusuka kuhele MP4 njenge AMR?

Layisha phezulu ihele MP4 futhi sizosusa umsindo, bese siguqula ikhodi ibe AMR. Akukho sinqumo sevidiyo sesibili futhi akukho phutha lomgangatho ngaphandle kwe-AMR codec.

Yini i-bitrate yomsindo i-AMR isebenzisa?

Iphutha le-AMR bitrate yi-192 kbps (libonisa ngaphaya kwengoma). Ungayishintsha ibe yi-320 kbps (audiophile) noma 96-128 kbps (ubizo / ipodcast / ifayela elincane). Ukhetho luvela ezinketho eziphezulu.

Sebenzisa ukhetho oluthuthukisiwe "umsinga womsindo" ukukhetha ngokucacile umsinga 0, 1, njll., noma uphinde uhlanganise wonke umsinga ku-multi-track AMR container uma AMR isekela lokhu.

Ingabe ukukhishwa kwe-AMR kuyisistereo / mono / 5.1?

Isixhumanisi sohlelo sigcinwa kusuka ku-MP4 ngokuzenzakalela — i-5.1 MP4 ikhiqiza i-5.1 AMR lapho i-codec ixhasa khona (AAC, FLAC, OGG). Ungacindezela i-stereo noma i-mono nge-channel-downmix option, esetshenziswa ku-podcast workflow.
