Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i MP2 encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i MP2 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye. MP2 ilahlekile kodwa isebenzisa ibanki yecebo lokucoca ulwelo elilula kune MP3, eqhelekileyo isebenza kwi 192 ukuya kwi 384 kbps.

Ingaba i-MP2 yesandi igcina i-sample rate yangaphambili?

Ngokungagqibekanga ewe — 48 kHz yesandi kwi WebM yakho ihlala i-48 kHz kwi-MP2 yemveliso. Ukukhupha i-CD okanye ukulungelelanisa umdlali okhoyo ungakhupha i-sample ukuya kwi-44.1 kHz nge-sample-rate dropdown; i-resampler ikwi-SoX-grade esezingeni eliphezulu.

Ndingagcina i-MP2 njenge-stereo, mono, okanye i-5.1 surround?

Ubeko lwesiqhagamshelanisi lugcinwa ukusuka kwi WebM ngokumiselweyo - i-5.1 WebM ivelisa i-5.1 MP2 ukuba i-MP2 codec ixhasa loo nto (AAC, FLAC, OGG, Opus).
