Ukudibanisa ezantsi kusetyenziswa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-ndawo zidityanisiwe kwinqanaba eliphantsi. Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo iphela xa oku kwenzeka. I-M4R i-Apple kuphela kwaye ikhawulezisa ubude; nantoni na engaphezulu kwemizuzu engama-40 ilahlekile ngokucothayo yifowuni.

I-M4R ekhutshiweyo isebenzisa i-bitrate yesandi ethini?

I-bitrate emiselweyo ye-lossy M4R yi-192 kbps, ebonisa ngaphaya kwengoma. Ungayicima i-320 kbps (audiophile) okanye i-96-128 kbps (ilizwi / ipodcast / ifayili encinci). I-bitrate esuka ezantsi ivela kwiinketho eziphambili phambi kokuba ucofe uguqule.
